AI 时代，别把思考外包

ai时代来了 我们很多人即将放弃思考了
因为ai能替代很多东西
我们不需要去做那么多繁杂的工作了
我们也不需要翻箱倒柜去查资料了
这些简单无脑甚至复杂有脑的工作ai
都能帮我们完成

但是我们依然需要独立思考 一是因为现在还不是通用人工智能
二是即使通用人工智能来了
领导社会发展的依然是独立思考的人
这个社会ai发展淘汰的不是不会用ai的人
而是只会用ai不会独立思考的人

完美的计算机规划

什么是理想的大学规划

我们假设学生非常喜欢电子信息，且顺利高考报志愿选择到电子信息大类或者计算机/软件/人工智能/大数据等专业并且开始大学学习。
我们假设学生所在本科院校为强211或者中985，我们假设学生所在学校不是两电一邮是一个”综合性大学“，那么孩子该怎么通过自己努力实现逆袭呢。

首先在高考完的暑假，放松之余，养成健康的生活习惯，锻炼身体，保持身体健康和充足的精力。其次，在休息之余就干两件事，第一学英语，第二学python。英语只要在高考的基础上，达到四六级能过的水平即可，真的，这对于高考英语120+的正在英语水平癫疯的学生来说是轻而易举的事情，打好英语基础，一是为了自己的编程做铺垫，二是养成良好的英语学习习惯，这样就能在每天的积累中顺利考过四六级，考过雅思，甚至能利用上本科学院的报销机制，实现白嫖雅思。

好，接下来我们说怎么学python，其实也同样的，不需要达到特别高的水平，只需要把b站随便挑一个免费的课即可，每天学两个小时，用不了一个月，你将彻底读懂一门语言，跟着视频每一个代码都敲一遍，有一个月的时间，你将彻底掌握好一门语言的基础，接下来，当你正式进入大学开始课程学习的时候，你将特别轻松，甚至能很顺利的开始你的acm生涯，这样四年下来，你跟同学拉开的差距，可能是指数级别的。

好的，我们假设你能顺利完成刚才提到的两件事情，其实真的不难。这里其实我们还忽略了高中学信息竞赛的前提，如果高中已经有基础，你在大学将实现降维打击。就这么说，对于绝大部分按部就班或者不怎么上进的同学来说，他们毕业准备考研找工作的水平，都无法达到你高二的巅峰水平。人与人的差距，就是这么大。

好的，我们开始大一的课程，这时候你会学一些数学课，其实数学课永远都是重要的，但是把，这时候我们需要做出一些决战，就是你数学基础好不好，如果你是数学颇有天赋，对于导数颇有研究，那么高等数学对你应该不会有什么太大的压力，你只需上课好好听，作业好好写，考个8090分应该问题不大。线性代数更是，只需要掌握最核心的东西，你将不会遇到太大的困难。如果，你的成绩不是很好，那么你学数学就会比较吃力了。这时候我们就需要考虑一件事情了，自己是不是需要保研，或者自己想不想读博，自己想不想搞科研，自己是不是想马上就业，这时候就需要根据自己的需求考虑前进的方向。

因为一般学校的数学课学分都是很高的，换句话说，如果你高数考70，你基本与保研无缘了。如果你说，我想争一下保研，那么好，你要做的事情就比较明确了，刷题，真的像高中那样学习，如果你真的怎么也很难搞懂原理，那么简单，你会做题，能考高分就可以了，多做几遍，把题目答案背下来，你早晚会明白原理的。

如果你不想争保研，想去考研或者直接就业，那么好说，做必要的作业，复习必要的内容，只要70分就足够了。

好的，大一你还会有一门c/c++，应该会讲特别基础的东西，这些对于已经会python的你，很容易融会贯通，你会很容易的做完测试，大作业，甚至会成为很多同学的大腿，吸引异性的关注等等等等。同样的，你会节省出很多时间，可以用在你不好的数学上，所以，如果你编程课很顺利，你的数学应该也不会差。

好的，大一的课应该是比较忙碌的，这时候的你们应该都比较卷成绩，这时候的大家应该也都是一张白纸，你们也没有学专业课，你们之间的差距也非常的小。这时候你该做什么了呢。好的，这时候你应该就会知道一个东西，他叫数学建模，对，已经会python的你，应该要参加这个数学建模了，一个国赛，一个美赛，你在学习数学建模的期间，又接触到了机器学习，深度学习，人工智能，你又发现了一个叫kaggo的东西，你知道了什么是服务器，你知道了你能用colab使用免费的服务器，你自学了linux，你会用LLM辅助你完成机器学习的代码，你开始在kaggo玩起来，你知道了什么叫深度学习，你发现数学建模跟dnn很多相似的地方，你对这个领域越来越感兴趣了。到了大二，你们开始学很多专业课，你知道了一个叫leetcode的东西，你听老师学长学姐说找工作要刷leetcode，你抱着试试看的心态，发现好难，什么都不会，这太正常了，比较你的数据结构算法课程刚刚开始，你开始学算法，你发现这东西好难，什么都不会，还容易忘，还好，你有python的基础，有了大一一年对编程的经验，你能通过自己的反复练习，逐渐掌握了很多算法，你开始手撕，你开始写leeicode，leetcoide开始成为你的日常，大二上学习，你在各种专业课之余，疯狂提升你的代码能力，你努力学计算机组成，计算机网络，离散数学等，尽管很多都是新鲜东西，你还是靠着自己的记忆力，疯狂提升自己的计算机网络知识，离散数学罗技，各种算法问题，你的能力在进一步提升着，由于你养成的良好习惯，你应对所有课程游刃有余，这时候你在想，很多同学都在疯狂参与社团活动，我要不要参与一下，于是你在大二也找了一个社团参加，环节你每天丰富的学习生活。

大二上结束了，你们完成了很多专业课的学习，你发现自己对深度学习有一定的狂热，你开始认识到，想去找老师做科研，发论文，由于你已经有了kaggo的基础，老师看到你的简历非常开心，又来了一个能带硕士发论文的本科生，你看着老师给你的课题和服务器，你有了自己的工位，有了带你的师兄，你欣喜若狂，你现在可以疯狂的压榨师兄，疯狂的提升自己。由于你的代码能力非常扎实，尽管很多深度学习的概念你还是第一次知道，虽然你还没上完机器学习深度学习的选修课，但是凭你经常打比赛的经验，kaggo的经验，还有你一直以来的英语基础，你能不是很困难的读懂师兄给你的论文，通过几周跟师兄的讨论，你明白了自己要做的东西，师兄也很给力，因为他也想发论文。就这样，你们齐心协力下，赶上了夏天aaai的投稿，你也就这样度过完了你的大二学年。这一年，你不仅算法有了质的提升，你的课堂成绩也没落下，尽管达不到前几名，你的综合成绩还是能隐隐约约够到保研的边缘。

你上了大三，你跟师兄的文章在几次修改之后终于发表，你也有了人生中第一个ccfA，尽管不是一作，但是学生二组也给了你充足的信息，你决定继续在实验室实习，同时大三你们的课程已经不多了 ，你觉得是不是该去找个实习了，所以你接触到了java，html css，go，你接触到了很多业界在用的技术语言，你开始自己上手学习，你开始跟着github上的项目开发，大三的寒假，你找到了寒假实习，是你心仪的大厂，因为大三下已经没有什么课程了，你比较顺利的跟指导老师完成沟通，在大厂完成了两个多月的实习，在实习过程中，你有一个很好的mentor在他的指导下，你学习到了非常多东西，你也成功有了你的第一个大厂开发项目经理。同时，你的文章也开始投稿。大三下，马上你们即将面临保研，你的成绩还不错，运气好是能保研的，但是你也丝毫不慌，保不上就考研呗，跟做科研的老师说一声一定会捞自己的。大三的夏天，好消息来了，你保上了，有几个角度可以解释吧（数学建模加分了，自己新的一作论文发表了加分了，成绩本身就是够的）。（大三的暑假要不要再加一个暑期实习呢，其实都行，毕竟现在已经基本什么都有了）

好了，你大四了，你保研了，因为你有论文发表，还有大厂实习，你成功保研到一所很top的学校，跟一个很强大的老师。做了一年多的科研，你认识到了自己还是喜欢干开发。你决定不读博，好好干老师的项目，同时精进自己的技术，多找实习。研一一年，你边划水上课，边了解老师的项目，同时精进了自己的leetcode完善自己的简历，这时候，你的leetcode已经到达了1000+题目，基本已经熟练掌握各种题目，大厂笔试对你来说手拿把掐，你不仅顺利完成导师的项目，也在研一暑期研二暑期分别找到实习，这时候你已经完成了各种岗位的实习，显然，研三的秋招对你来说根本不是事。

好了，写到这感觉根本写不下去了。博主感觉这几年大学最失败的一件事情就是大一高数没学好，就是说大一参加的活动还是太多了，自己还摆烂，离谱哇，就是说高中跟社会脱节太多了，大一想把什么都找回来，还是有点难度的。

从高数74分之后基本干什么都是难于上青天，自己也不知道计算机的职业规划，就浑浑噩噩，一直被拉开着差距。

大二有一点觉醒了，但是有很多社团学生组织事情在忙，其实也是在自我学习的过程，也参加了很多竞赛，为了增强自己吧，也确实一直在进步，也谈恋爱了，这么看我的大二是真的忙啊。大三就都是专业课了，这个时候也已经知道人与人的差距了，想努力差距还是很大，但是也尽力了吧，写大作业，会各种知识，努力刷分保研。大四就是在准备考研了，知道自己保研之后就去搞科研了，有一说一大四这一年还是挺努力的，努力在搞科研，所以研一的时候觉得自己很与众不同，因为大家都在玩耍，摆烂，考研的时候我在努力。但是博一一年确实又有点难受呀，因为全身心投入到科研和抗压中了。浪费了很多生命。博二一年基本就做了一件事，申请同时搞论文。这么看，我博一博二的时间如果分一部分到leetcode和项目，我现在应该没有这么痛苦。换句话说，如果我今年一年疯狂准备加实习，我明年的招聘应该是能轻松cover大厂的吧，这么看好像是，我做的还行啊哈哈哈哈哈哈，我好像也就是做到了普通人的极限了。毕竟我大三的时候也在努力刷题了，

逻辑回归一文通：二分类 vs 多分类（含 MLE、求导、正则、优化）

这篇是把我们前面所有讨论系统化的一份速查与学习笔记：从二分类逻辑回归到多类 softmax 回归，讲清楚 odds/logit、MLE、交叉熵、梯度推导、正则化，以及 GD/牛顿法等优化要点。可直接作为复习提纲。

0. 问题设定与记号

  • 训练集：({(x_i, y_i)}_{i=1}^N)，(x_i\in\mathbb{R}^d)
  • 二分类：(y_i\in{0,1})；多分类：(y_i\in{0,1,\dots,C-1})
  • 线性打分（logits）：对类 (c) 记 (s_c = w^{(c)\top} x)

logits 不是概率，是“未归一化的分数”；要变成概率需要 sigmoid（二类）或 softmax（多类）。

1. 二分类：Logistic Regression

1.1 Sigmoid 与 logit

  • Sigmoid：
    [
    \sigma(z)=\frac{1}{1+e^{-z}} \in (0,1)
    ]
  • 概率：
    [
    p(x)=P(y=1\mid x)=\sigma(w^\top x)
    ]
  • odds（几率比）：(\dfrac{p}{1-p})
  • logit（对数几率）：(\mathrm{logit}(p)=\ln\dfrac{p}{1-p}=w^\top x)

logit 把 ((0,1)) 映射到 (({-}\infty,{+}\infty))，可用线性函数建模。

1.2 似然、对数似然与损失（交叉熵）

  • i.i.d. 假设下的似然：
    [
    L(w)=\prod_{i=1}^N p_i^{y_i}(1-p_i)^{1-y_i},\quad p_i=\sigma(w^\top x_i)
    ]
  • 对数似然：
    [
    \ell(w)=\sum_{i=1}^N \big[y_i\ln p_i + (1-y_i)\ln(1-p_i)\big]
    ]
  • 损失（负对数似然 = 交叉熵）：
    [
    E(w)=-\ell(w)= -\sum_{i=1}^N \big[y_i\ln p_i + (1-y_i)\ln(1-p_i)\big]
    ]

为什么从似然变成损失？ 最大化 (\ell(w)) ⇔ 最小化 (-\ell(w))，便于用最小化优化器。

1.3 梯度与更新

[
\nabla E(w)=\sum_{i=1}^N (p_i - y_i),x_i
]

  • 批量/小批量 GD：(w\leftarrow w-\eta\nabla E(w))
  • 阈值判别：(\hat y=\mathbb{I}[p(x)\ge \tau])（默认 (\tau=0.5)，可按业务调整）

1.4 正则化（以 L2 为例）

[
E_\lambda(w)=E(w)+\frac{\lambda}{2}|w|2^2,\quad
\nabla E\lambda(w)=\sum_i (p_i-y_i)x_i + \lambda w
]

权重衰减视角：
(w\leftarrow (1-\eta\lambda)w-\eta\sum (p_i-y_i)x_i)

作用：抑制过拟合、提升稳定性（抗共线性），贝叶斯视角等价于高斯先验。

2. 多分类：Softmax（Multinomial Logistic Regression）

2.1 概率模型（两种等价写法）

  • 标准 softmax（常用）
    [
    p_c(x)=\frac{e^{w^{(c)\top}x}}{\sum_{k=0}^{C-1} e^{w^{(k)\top}x}}
    ]

  • 参考类（与课件一致）
    取 class 0 为参考，(w^{(0)}\equiv 0)：
    [
    P(y=0|x)=\frac{1}{1+\sum_{k=1}^{C-1}e^{w^{(k)\top}x}},\quad
    P(y=c|x)=\frac{e^{w^{(c)\top}x}}{1+\sum_{k=1}^{C-1}e^{w^{(k)\top}x}};(c>0)
    ]

softmax 对“整体平移”不变：(s_c\mapsto s_c+a) 概率不变。选参考类只是去冗余，不影响预测。

2.2 交叉熵与 MLE

  • One-hot 标签 (y_{ic}\in{0,1})，(\sum_c y_{ic}=1)
  • 损失（不含正则）：
    [
    E(W)=-\sum_{i=1}^N\sum_{c=0}^{C-1} y_{ic},\log p_{ic}
    ]

2.3 关键梯度结论（单样本 → 批量）

  • softmax 的核心梯度恒等式：
    [
    \frac{\partial \ell_i}{\partial s_{ij}}=p_{ij}-y_{ij}
    ]
  • 链式到参数：
    [
    \frac{\partial \ell_i}{\partial w^{(j)}}=(p_{ij}-y_{ij}),x_i
    ]
  • 批量求和 + L2 正则：
    [
    \boxed{;\frac{\partial E}{\partial w^{(j)}}=\sum_{i=1}^N (p_{ij}-y_{ij})x_i+\lambda w^{(j)};}
    ]

向量化（最实用）：

  • 设 (X\in\mathbb{R}^{N\times d}), (W\in\mathbb{R}^{d\times C}),
    (S= XW), (P=\mathrm{softmax}(S)), (Y) 为 one-hot
    [
    \boxed{;\nabla_W E = X^\top (P - Y) + \lambda W;}
    ]
    （若用参考类法，固定第 1 列为 0 且不正则/不更新。）

2.4 学习规则（GD / mini-batch）

[
w^{(j)} \leftarrow w^{(j)} - \eta\Big(\tfrac{1}{|B|}!\sum_{i\in B}(p_{ij}-y_{ij})x_i + \lambda w^{(j)}\Big)
]

预测：(\hat y=\arg\max_c p_c(x))

3. Sigmoid 还是 Softmax？

  • 互斥单选（只能属于一个类） → softmax + 多类交叉熵
  • 非互斥多标签（可多选） → 逐类 sigmoid + 二元交叉熵（one-vs-rest）

二分类中，“一个 sigmoid”与“2 类 softmax”是等价的：
(P(y=1)=\dfrac{e^{s_1}}{e^{s_0}+e^{s_1}}=\sigma(s_1-s_0))

4. 为什么损失凸却没有封闭解？

  • 逻辑回归的损失（交叉熵 / log-sum-exp）对参数是凸的 ⇒ 全局最优存在且唯一（加适当正则）。
  • 但一阶条件是非线性方程组（包含 sigmoid/softmax 的指数项），无法像线性回归那样解出 (w) 的显式封闭式。
  • 故需数值优化：GD/SGD/Adam/L-BFGS/牛顿(IRLS) 等。

5. 优化方法要点

5.1 一阶法（GD/SGD/Adam）

  • 便宜、可扩展到大数据；配合标准化、动量、权重衰减、学习率调度、早停。

5.2 二阶法（牛顿/IRLS，拟牛顿 L-BFGS）

  • 利用 Hessian（或其近似），局部二次收敛、迭代步数少；
  • 每步解线性方程，计算/存储较重，适合中等规模；
  • 逻辑回归 IRLS 形式：
    [
    \Delta w = (X^\top R X + \lambda I)^{-1} X^\top (y-p),\quad w\leftarrow w+\Delta w
    ]
    其中 (R=\mathrm{diag}(p_i(1-p_i)))。

6. 决策阈值与评估

  • 二分类默认阈值 (\tau=0.5)；可按业务调优（ROC/PR 曲线、Youden/最佳 F1 等）。
  • 多分类一般取 (\arg\max)；不平衡可结合代价敏感或后处理。

7. 实现清单（Checklist）

  • 特征标准化/归一化
  • 偏置项：拼 1 或单独参数（通常不正则化偏置）
  • softmax 数值稳定：行内减最大值（log-sum-exp trick）
  • 正则系数 (\lambda) 与学习率 (\eta)：验证集/交叉验证调参
  • 小批量、早停、权重衰减；必要时用 L-BFGS
  • 多分类参考类法 or 标准 softmax：预测等价，实现选更顺手的

8. 公式速查（Cheat Sheet）

二分类
[
\begin{aligned}
p_i&=\sigma(w^\top x_i),\
E(w)&=-\sum_i \big[y_i\ln p_i+(1-y_i)\ln(1-p_i)\big]+\tfrac{\lambda}{2}|w|^2,\
\nabla E(w)&=\sum_i (p_i-y_i)x_i+\lambda w.
\end{aligned}
]

多分类（softmax）
[
\begin{aligned}
p_{ic}&=\frac{e^{w^{(c)\top}x_i}}{\sum_k e^{w^{(k)\top}x_i}},\
E(W)&=-\sum_{i,c} y_{ic}\log p_{ic}+\tfrac{\lambda}{2}\sum_c|w^{(c)}|^2,\
\nabla_W E&=X^\top(P-Y)+\lambda W.
\end{aligned}
]

9. 常见问答（FAQ）

Q1：多分类一定要指定“class 0”吗？
A：不需要。参考类只是去冗余的一种参数化；标准 softmax 学 (C) 组权重即可，预测等价。

Q2：二分类不用 sigmoid 行吗？
A：可以。用二类 softmax等价；或用 SVM/hinge 等非概率方法。

Q3：为什么要正则化？
A：控制模型容量、抑制过拟合、提升数值稳定性；L1 得稀疏，L2 稳定抗共线，Elastic Net 折衷。

10. 参考实现（极简伪代码）

向量化梯度（softmax + L2）：

# X: (N,d), Y one-hot: (N,C), W: (d,C)
S = X @ W                       # (N,C)
S -= S.max(axis=1, keepdims=True)
P = np.exp(S) / np.exp(S).sum(axis=1, keepdims=True)
grad = X.T @ (P - Y) / N + lam * W
W -= lr * grad

11. 结语

  • 二分类：sigmoid + 交叉熵 + (p-y) 梯度
  • 多分类：softmax + 交叉熵 + (P-Y) 梯度
  • MLE → NLL（交叉熵）：最大似然 ⇔ 最小负对数似然
  • 凸但无封闭解：用数值优化（GD/L-BFGS/IRLS）
  • 正则化：更稳、更泛化

记住两条黄金公式即可快速复原一切：
(\nabla E_{\text{binary}}=\sum (p-y)x+\lambda w)；
(\nabla E_{\text{multi}}=X^\top(P-Y)+\lambda W)。

我们再继续展开discrimination的问题

有很多机器学习和深度学习是discrimination的

但是现在是生成式模型的时代generation

以中石化第一节人工智能竞赛为例，题目一是一个简单的分类问题，但是难点在于类不平衡

所有我们默认先使用分类的模型

因为是多分类问题，所以自然不能使用逻辑斯特回归

想到分类擅长的SVM改进版，是能应对多分类问题的

然后贝叶斯方法和决策树

随机森林

然后还有无监督knn方法

在解决这个数据挖掘问题的过程

Logistic 回归：用线性决策函数，最大化正则化对数似然（等价最小交叉熵）学到权重，输出 sigmoid/softmax 概率，适合近线性可分数据。

SVM：通过合页损失 + 正则寻找最大间隔超平面，配核技巧映射到高维以处理非线性边界。

朴素贝叶斯（NB）：假设特征在给定类别下条件独立，先估
𝑝(𝑥∣𝑦)p(x∣y) 和 𝑝(𝑦)p(y) 再用贝叶斯定理求 𝑝(𝑦∣𝑥)
p(y∣x)，简单快速但偏强假设。

决策树：按信息增益/基尼指数递归划分特征空间形成规则树，叶节点给类别，易解释但单树易过拟合。

随机森林：对样本与特征做随机子采样训练多棵弱相关树并投票/平均，显著降方差、鲁棒好、调参友好。

Verse9.22

我砸下的拳头 赶走了我的整个青春
看着停止不动的修改日期 我知道早已经回不到过去
推杯换盏的酒席之间 是最美好的青春回忆
我们早就各奔东西
之间没有了太多交集
也许共同的回忆永远留下了印记
你们的华语还留在我脑海里

都说青春是最美丽的
我也不能算是辜负
这个社会的真相就是你无法拥有对当下的沉溺与对未来的期待
想要未来过的去当下就得努力

说是浪费吗，其实也不尽然吧
大一想体验生活
我也确实进步了也确实什么都解除了
我甚至用一年追赶了三年的步伐

大二开始努力开始涉猎更广泛
但是发现自己的差距还不是一点半点

大三就已经开始了焦虑
现在我敲打键盘已经开始身体不适
大三不得不对未来考虑

已经变成了老学长但是其实内心还只是个小孩

大四一切尘埃落定
我却被迫开始长大

六年时间已经过去
我早就从学生身份剥离

羡慕那些年轻人有明媚的朝气
但是我却不得不接受这个世界的残酷

如果说大一大二我是完美的理想主义者
单三大四就是社会给我上的第一课

现在的我只知道工作

我知道
我永远有一颗年轻的心

那些理想主义者

总有一天我会去找回那些朋友

我会拍很多视频

我会努力

让现实接近理想的

我真的

斗罗大陆

我是理想主义者

多和年轻人接触吧

Verse1

不是不想买罪 是买不起太贵
每天只能吃着鸡饭 不敢加鸡蛋 对未来充满期盼
物质生活不是非常富足 但是想出国就得先学会孤独
立锥 递归
笔耕不辍
给她足够的选择权 不需要等到过年
不是那xxxx的贵族 劳动人民的双手用来创造财富

之前 十年
“Time’s Up” oldschool type beat
赚了满身的人民币 、东风六十一

我想坐着飞机去国外看看 看那地理书中描绘的奇观
他们居然告诉我无法参观 因为中国人的举止不端
还在搞无谓的种族歧视 你是不是觉得特别有意思
今天的中国早已不是塌方的历史 我们的山河孕育大方的气质 不是你回家的地址
历史的屈辱必须记住，不能忘了民族的去处
反对法西斯绝非空谈，苗头一现就要扼杀在摇篮
天安门广场前的最佳列队，就是让你们跪下谢罪
我们的范围是打击全球，看你们还敢不敢去抢原油
七十六年前那声怒吼，中国人民翻身当家作主
人民的双手本该创造财富 不该被贵族奴役束缚
前辈付出的牺牲叫革命，换来的果实才是和平
百年屈辱曾让我们低头，如今昂首睥睨整个地球
中华民族爱好和平，但若不收拾你们肯定不行
印尼华人仍遭欺凌，我们的武器让敌人打个激灵
民族的脊梁在这个时代挺起 伟大的复兴像跃龙门的锦鲤
多极世界在摇篮孕育，努力之外还要加上运气
不是为了霸主，不是争第一，而是为共同体打好根基
和平共处是我们的向往，水来土掩，兵来将挡
不仅人民币升，人民必胜，投入一切哪怕毕生
未来格局我不能确定，战争大事我无法说
唯有自强是命中注定，你若欺我，就让你回家治病
公平正义要靠拳头来争取 他人的施舍怎么能相信
试看未来全球是何世界？必将是赤旗飘扬的致谢

Free 老百姓 freestyle
也许缘分之中我遇到了自己的贵人（也许缘分之中我遇到了自己的贵人）
寂静的血液沉寂之中即将开始不止沸腾（血液不再沉寂即将开始不休止的沸腾）
奉献到肝脑涂地心甘情愿做知识的奴隶（不想被唾弃成为一个废人）
学习的机器发奋图强根本不认识了我自己（大江大河总是由小溪汇成）
一夜之间洗心革面明白了想成功的途径（他的蔑视总是回荡在我脑海之中挥之不去）
没有捷径只有脚踏实地的努力（终于明白想要成功只有依靠努力）
他的蔑视回荡在我脑海之中挥之不去（咸鱼翻身我真的知道有多不易）

（也许缘分之中我遇到了自己的贵人）
（血液不再沉寂即将开始不休止的沸腾）
（不想被唾弃成为一个废人）
（大江大河总是由小溪汇成）
（他的蔑视总是回荡在我脑海之中挥之不去）
（终于明白想要成功只有依靠努力）
（咸鱼翻身我真的知道有多不易）

血肉做的心脏承受了太多不属于这个年龄的情绪(血肉做的心脏承受了太多情绪)
看着手腕上的刀疤想想要不要继续活下去(手背的疤痕提醒着我一定要活下去)
我讨厌自己糊涂的稚气低下的智力（我讨厌自己的稚气和低智力）
是不是只能天才才能做出点成绩（是不是只有天才才能赢下胜利）
目光所及留下来的只有她活泼的背景（目光所及只有她活泼的背影）
拼尽全力想出风头吸引她的注意（拼尽全力只为得到一点注意）
（洗心革面我想有点出息）
我一个人只能自己拿自己的主义（自己的路只能靠自己定义）

十年河东十年河西不是说说而已（十年河东 十年河西）
厚积薄发给你看看少年的志气（厚积薄发 少年稚气）
怎么可能背叛自己的阶级接受他们的接济（怎么可能背叛自己的阶级接受他们的接济）
我永远是农民的儿子不会离开这片土地（农民的孩子）
想想蜕变之后总很难接受自己( 咸鱼翻身很是不易）
(每一步都得拼尽全力）
（尊严踩在鞋底也要拾起
抬头仰望星空我不认命）

（终于接受了平庸的躯壳
可心底的火焰从未停过
自暴自弃多少次摔落
可梦想让我再次把刀口封锁）

直到有一天终于接受了自己的平庸
每一个九点四十的晚上抬头仰望星空
多少次反复自暴自弃
尊严早就被践踏在鞋底
每天早上即使睡眼惺忪也得警惕敲响的警钟
拼搏记在心中学习岳飞报国精忠

二十四岁的自己看着镜子掩面而泣
看着不久的将来马上三十而立
一事无成到现在到底可不可惜

坚持到最后不敢相信能够一步登天
对凡人来说我好像已经超脱升仙
新的开始才知道自己是真的开始
开始接受此生最沉重的打击

······················································
想等上山巅
看烽火狼烟
古镇中外的豪杰还在人间
不说大话相信人定胜天

音乐激昂 踏上脚步
敞开心房 不走小路
世界有多少苦难是不可战胜
用尽全力了我就开始范疯

那是一个阳光明媚的早晨
举起手看着上面的掌纹
抬起头被老师敲了一下脑门
开始续写我人生的爽文

不能同时拥有青春和对青春的向往
回忆起当时我依然为之倾倒
痛苦与焦虑全都被抛在脑后
能够追忆起的只有欢笑与欣慰
自己这一路走来生活颇为丰富
不是神仙却有神仙风骨
洒脱人生是我此生信仰
大小姐驾到丝滑进场
从那天起我突然开始成长
紧闭在小的房间好像折断翅膀
突然听到新闻里面的郑爽
感叹自己总是没有钱只能孤芳自赏

2025-09-04：关于语言和声音的完整对话 Language & Voice Full Conversation

🗣 场景对话 Dialogue

You（你）: Let’s keep it casual today.
今天我们随便聊点轻松的吧。

Me（我）: Sure thing, we can absolutely switch gears and keep it casual! Just let me know what kind of everyday topic you have in mind, and we’ll dive right in.
当然可以！我们完全可以把话题切换到轻松日常。你可以随便提个话题，我们就从那开始聊。

You（你）: How about languages? I feel in Europe people can pick up each other’s languages more easily.
那说说语言吧？我感觉在欧洲，人们更容易学会彼此的语言。

Me（我）: Yeah, absolutely! Languages are so fascinating that way. In Europe, like you said, you have languages like German, English, and French that share some linguistic roots and are geographically close, so people might find it a bit easier to pick up each other’s languages.
是的！语言真的很有趣。就像你说的，在欧洲，德语、英语和法语有共同的语言根源，而且地理位置很接近，所以人们可能更容易互相学习。

Me（我）: And then, like you mentioned, in a place like China, you’ve got Mandarin as the official standard language, but there are so many different regional dialects and local varieties. It’s like a rich tapestry of languages within one country. Even though they’re all considered forms of Chinese, like Cantonese or Shanghainese, they can sound pretty different from each other.
另外，比如在中国，普通话是官方标准语言，但还有很多不同的地方方言和变体。就像一幅丰富的语言拼图。虽然都算是汉语的形式，但像粤语和上海话听起来却很不一样。

You（你）: So all of those are just dialects?
所以这些都叫“方言”吗？

Me（我）: Yeah, great question! So when we talk about these different kinds of language varieties within a single country, we usually call them “dialects.” For example, in China, Mandarin is the standard language, but Cantonese, Shanghainese, or Sichuanese would be referred to as different dialects of Chinese.
对，这是个好问题！当我们说到一个国家内部的不同语言变体时，通常就叫“方言”。比如在中国，普通话是标准语言，而粤语、上海话或四川话就算是不同的方言。

Me（我）: In English, the term “dialect” just means a regional or local variety of a language. It’s a way to recognize that while everyone is speaking a version of the same language, there are local differences in pronunciation, vocabulary, or grammar. So you can just say they’re different dialects of the same language!
在英语里，“dialect”这个词就是指语言的地区性或地方性变体。意思是大家说的都是同一种语言的版本，但在发音、词汇或语法上有差异。所以你可以说，它们是同一种语言的不同方言。

You（你）: What about accent? Is that the same thing?
那口音呢？是不是和方言一样？

Me（我）: Absolutely! So those terms—dialect, accent, and idiolect—each have a slightly different meaning.
没错！其实“方言、口音、个人言语特征”这些词意思都有点不一样。

Me（我）: A dialect is a broader term that refers to a variety of a language that includes differences in vocabulary, grammar, and pronunciation.
dialect（方言）是一个更广的概念，包含词汇、语法和发音的差别。

Me（我）: An accent, on the other hand, is specifically about pronunciation. It’s the way words sound. So you can have different accents within the same dialect. For example, people in different parts of the English-speaking world might speak the same dialect of English but with different accents.
accent（口音）只和发音有关，就是词听起来的方式。同一种方言内部也可以有不同的口音。比如在不同地区的英语国家，人们可能说的是同一种英语方言，但口音却各不相同。

Me（我）: An idiolect is even more specific: it’s the unique way that an individual person speaks. Everyone has their own idiolect, which is like your personal “flavor” of the language.
而 idiolect（个人言语特征）更具体，就是一个人独特的说话方式。每个人都有自己独一无二的说话“风格”。

You（你）: What if the difference comes from social groups instead of regions?
如果差异不是地区，而是来自社会群体呢？

Me（我）: Ah, I think you’re referring to the term “sociolect.” So a sociolect is kind of like a dialect, but it’s specific to a particular social group rather than a region. For example, different social classes, professions, or age groups might have their own sociolects.
啊，你可能说的是“sociolect”。sociolect（社会方言）有点像方言，但它不是来自地区，而是来自某个社会群体。比如，不同的社会阶层、职业或年龄群体，可能会有自己的“说话方式”。

Me（我）: And another word is register. It refers to the level of formality or style of language you use in a particular context—like formal, informal, technical, or slangy.
还有一个词是 register（语域），它指的是你在不同场合使用语言的正式程度或风格，比如正式的、非正式的、专业的，或者俚语化的。

You（你）: Like being formal in a job interview and casual when chatting with friends?
比如在面试时说话正式一些，而和朋友聊天时就随意一点？

Me（我）: Exactly!
没错！

You（你）: Now, let’s switch to voices. How do we describe them?
那我们换到声音吧。声音该怎么描述呢？

Me（我）: Yes, definitely! When we talk about the qualities or dimensions of a voice, there are a few main aspects we often consider. One is loudness, which is basically how loud or soft a voice is.
当然！当我们描述声音的特征时，通常会考虑几个主要方面。第一个是 loudness（响度），也就是声音的大小。

Me（我）: Another is pitch, which refers to how high or low the voice sounds.
另一个是 pitch（音高），也就是声音的高低。

Me（我）: And then there’s timbre (sometimes called tone quality), which is the unique texture or color of the voice that makes it sound distinct.
还有 timbre（音色），有时候叫“音质”，是声音独特的质感或颜色，让它和别人不一样。

You（你）: Are there more aspects beyond those three?
除了这三个，还有别的吗？

Me（我）: Sure! Another key dimension of voice is tone, which can refer to the emotional quality or attitude conveyed by the voice—like whether it sounds friendly, serious, or sarcastic.
当然！还有一个是 tone（语调），它指的是声音的情感或态度，比如听起来是友好的、严肃的还是讽刺的。

Me（我）: And finally, there’s resonance, which is how rich or full the voice sounds depending on how the sound vibrates in the vocal tract.
最后还有 resonance（共鸣），它决定了声音是否饱满，取决于声音在声道里的共振方式。

You（你）: So, in total, five key aspects?
所以总共有五个主要方面？

Me（我）: Exactly! Loudness, pitch, timbre, tone, and resonance. Put them all together, and you’ve got a full picture of how to describe a voice.
没错！就是响度、音高、音色、语调和共鸣。把这五个结合起来，就能全面描述一个声音。

2025-09-11：每日英语日记 Daily English Diary

🗣 场景对话 Dialogue

You（你）:
Okay. Yeah, actually, from today, I’d like to start a plan as to improve my spoken English, to revise my pronunciation, the grammar, the usage of useful phrases. And I’d like to start from today, the 11th September 2025. Yeah, from today. Every day, I’d like to have a small talk with you about the things I see in today and the things I do. And I try to describe them in English. I try to use English to describe all my life, so English is not my mother language. And I’d like to you to help me. First, revise the error and polish my phrases, my words, and sentences. Okay. And second, write down the important things of our conversation and help me collect them in a format that helps me to revise and help them who is not proficient in English to have a look and may learn from it. Okay, let’s begin.

Me（我）:
Absolutely, that sounds like a great plan and I’m totally on board! We can treat it like a little daily English diary: you share what you see or do, I’ll help tweak your grammar and phrasing, and then I’ll jot down the key points so you have something to review later. Let’s get started!

You（你）:
So today, I woke up around 8 a.m., or at least that was my first wake-up. I actually went back to sleep for about another hour because, well, it was just one of those mornings. Eventually, I was woken up again by some noise at the door. It turned out to be my landlord letting me know that a package had arrived for me. He’d held onto it and sent me a message, so I went to pick it up from him.

After that, I tried to get a bit more sleep, but it was kind of a struggle, so I just got up properly around noon. Once I was up, I did the usual morning routine: washing my face, brushing my teeth, and so on.

Then, I ended up playing a game for about an hour. Honestly, I was procrastinating a bit because I had planned to review some class material and prepare for job hunting, but I wasn’t sure where to start, so I just played a game first. I know it’s not the best habit, but I’m working on it!

After the gaming session, I got down to business and solved some problems on LeetCode. Later, I messaged a friend to see if he wanted to have dinner together. He agreed and asked if I could come over to his area, despite the rain. I said yes and got ready to go out. The rain was actually really heavy—probably the heaviest rain I’ve seen since I came to Singapore—so I ended up pretty soaked by the time I got there. But we finally had our meal together at the canteen near his school.

After dinner, we went to his place where he helped me work on my resume and submit some job applications. We also played a few games at his place before I headed back home. Once I got home, I hopped on the computer, and now here I am, having this conversation with you.

Me（我）:
Great job describing your day! I polished your sentences a bit for natural flow and will highlight key points below.

🛒 场景一：扫码遇到问题 Scan Problem at Self-Checkout

🗣 Your Original Version

Yeah, how about the simulated situation that I encountered in my daily life?
For example, today at dawn in the night, I went into a supermarket and bought something.
And when I’m going to check, I come out with some problem.
It’s that I’m packed with four apples in a box.
And when I want to check this item, I choose the self-service.
And I need to scan the code printed on the box.
But I encountered some trouble.
It’s that the code is not the traditional line code or such kind of code.
It was a QR code.
So I met this trouble, and I can’t figure it out.
So I say to the service, and I ask her, how should I scan this item?
And she told me that I should use another scan gun hung at the shelf, I think.
I know I have some common problems describing this scenario.
Could you help me, give me some advice, and revise the problem, the errors?

✨ Polished Version

Today, in the evening, I went to the supermarket and picked up a few things.
When I was checking out at the self-service area, I had a little issue with one of the items.
It was a box that had four apples inside, and instead of a regular barcode, it had a QR code on it.
I wasn’t sure how to scan it with the usual scanner.
So I asked one of the store employees for help, and she told me I just needed to use a different scanner they had near the shelf that could read QR codes.
Once I did that, it worked fine.

  • self-service checkout 自助结账

Another topic is that, I just give an example, is that in one day, one of my friend made a deal with me,
that we will meet at next day’s lunch time at some place in Boston, and have a meeting, have some food, and maybe go to the supermarket.
But, in the next day, my friend sent me a message saying, maybe I need to cancel my deal, duration, appointment, or some words,
because I do not have enough sleep, and so sleepy, I must fall asleep right now.
So at the lunch, instead of we together have some meal, I will ask for the delivery, so it may be a little expensive, but I have no other ways, so very sorry.
And, at that time, I was in sleep, but when the time I wake up and see the message in the mobile phone,
I got astonished, and I’m surprised, and a little angry, because that he canceled our deal so easily.
I’m a little not happy, so I sent the message to him, that if you want to save money, so do not order the delivery food, it costs a lot,
and you are not conscious with our appointment, I’m not happy with you.

✨ Polished Version

One day, a friend and I made plans to meet up for lunch the next day at a place we both knew.
We were going to grab a meal together and maybe swing by the supermarket afterward.
But the next day, my friend messaged me saying that they needed to cancel the plan because they hadn’t gotten enough sleep and were feeling really tired.
They said they were just going to order some delivery food instead, even though it might be a bit expensive, and they apologized for the last-minute change.
When I woke up and saw the message, I was pretty surprised and a little annoyed.
It felt like they canceled too easily, and I was kind of upset.
I messaged back saying that if they wanted to save money, they shouldn’t order delivery,
and that I was disappointed they didn’t take our plan seriously.

🧥 场景三：关于买衣服的讨论 Disagreement About Buying a Coat

🗣 Your Original Version

OK, another thing, I think maybe it is interesting, is that, for example, I now talked with my girlfriend about one thing,
is that she looks, have a look of some beautiful clothes, and she think it’s very nice, and famous, and it’s worth buying, I think.
But I think that clothes, actually the coat, is not so good, not only the material, also the brand, and the price is high.
And so I guessed his intention to buy the coat, and we have a discussion.
She told me that she would really want to buy something new clothes,
because nowadays in the cities, women should make up, and be elegant, and such things to be noble.
I don’t think that is proper, but I don’t come up with any other adjectives.
And I’m now in the opposite, I think, if you want to buy such an expensive thing, out of your range of money, I think it’s not good,
and you should have your plan of saving money.
And then she said she understands my idea, she got my opinion, and we should save money.
But I replenish, or add up, I think, I say, if you really want to buy something, the money,
even though today you save the money, but at last one day you will lose the money, maybe not in the coat, but in other ways, I think.
I think this is sensible, this makes sense, this idea.
And I don’t know, maybe some famous one said this opinion, and I think it makes sense.

✨ Polished Version

Here’s an interesting scenario.
My girlfriend was looking at a really nice coat—she thought it was stylish and kind of a must-have, even though it was a bit expensive.
I wasn’t so sure it was worth the price, considering the brand and the material, and I felt like it was out of her budget.
We had a little discussion about it. She said that in the city, it’s common for women to want to dress nicely and look elegant,
and she felt like having something new would help her feel more confident.

I explained my point of view: I thought it was important to save money and not splurge on something too pricey if it wasn’t necessary.
Eventually, she understood where I was coming from and agreed that saving money made sense.
I also told her that if she really wanted to buy something special, it’s okay to plan for it,
but we just needed to be mindful of not overspending. I think that’s a pretty sensible approach.

📚 Keywords & Notes

  • must-have item = 必买单品
  • splurge on something = 在某物上花大钱
  • out of budget / out of your range = 超出预算
  • plan for a purchase = 有计划地消费

🎓 场景四：AI 课最后一节与教授寄语 · Final Lecture & Professor’s Message

“Okay, please allow me to describe the scenario. Today, I have an AI introduction class lecture, and the professor Bo An, my teacher. So, today we finish the last class. Please let me to pre-mention that the class is online and in class at the same time, and also people can watch the recording. And at the beginning of the class, the professor said that at the beginning in the NTU school, the students may be the 20%, but at the last lecture, there may be only 5%. I will hear that I feel like the professor’s some idea, some thoughts, his opinion that maybe a little regret about the student that the attitude of taking the classes or something, I think he’s a little regret and we feel some pity. I also feel embarrassed and pity because I’m now on the internet and using the Zoom to taking the lecture, but I didn’t go to school because I’m lazy and don’t want to the one and a half hours traffic. This is the first thing I want to say.”

01:23 —

“Okay, and then the professor started the lecture, and at first, she introduced the theory of game and some reinforcement learning knowledge. And that’s not the point I want to say. The thing I want to say is that, almost at the last of the courses, the professor told us this may be the last course in the first half of the semester. And after this class, the next week, students will enjoy the recess week. And after the recess week, the first class, there may be another teacher to take the course. And even though I’m not the teacher teaching the class, if you have any questions, please feel free to email me. Here is a little… I don’t know how to say my feeling, but I do not feel good. Because maybe I do not take the class seriously, maybe. And that’s what I’m feeling.”

02:25 —

“Okay, and what I want to say is that also besides this, the professor Boan found something else. He said, he took some example, such as the Nobel Prize winner last year, Hinton, is known as the father of deep learning. And even though he made a great contribution to the neural network and won the Nobel Prize, but now maybe he can’t really catch up the latest large language model and such technologies. But in today, with the development of large language model and some aged technology, each of the company, one of the biggest technology company need the talent young man, especially the excellent young man. So he told us that he’s starting digging into the technology, collaborate with others, collaborate with the industry. And today’s world need young man, young talent man. And I know what he’s saying is that we encourage us to push up, push ourselves up and work hard to get not only a good salary, but also making some really contribution in the memory of the history book. Maybe I think I don’t know what I’m saying, but I feel gratitude about the professor. And he is really a man that taking care of the student, giving us lots of expectations and the vision asked to do make a few work, make a deal and such expression. And I don’t know how to say, because this is the last conference of the professor. And I think this professor is such a good man. And he really expected us to have a bright future.”

00:22 —

“Okay, so how you give a judgment of the things the professor said and the things we talked and how should I feel about those things and how should we work hard to maybe not pay for or not be so bad with the expectation, I don’t know.”

00:08 —

“Okay, about this topic, do you have any additional material or things that may teach me? Then I learn some experiments.”

00:09 —

“Okay, let’s stop today’s talk. Can you later give a conclusion of today’s conversation in a regular format, okay?”

✨ Polished Version

Today was the final session of my AI introduction course taught by Professor Bo An.
The class was hybrid—some attended in person, others joined via Zoom, and recordings were available. At the start, the professor noted that attendance often drops from about 20% at the beginning to around 5% by the last lecture. He sounded a little disappointed, which made me reflect on my own engagement because I joined online to avoid a 1.5-hour commute.

Before wrapping up, he said this would be the last class before recess week, and that another instructor might take over afterwards. Even so, he encouraged us to email him anytime with questions.
He also mentioned Geoffrey Hinton, pointing out that even pioneers can’t keep up with every new development in large language models. His broader message was that today’s tech world needs young talent to learn quickly, collaborate with industry, and aim to make meaningful contributions.
I felt grateful for his guidance and motivated to stay more engaged—not just for grades or salary, but to do work that truly matters—while also a bit guilty about my attendance.

Note: Geoffrey Hinton received the 2018 ACM A.M. Turing Award (often called the “Nobel Prize of Computing”) for deep learning.
