Patch as Intelligence
We’ve been in a environment that evaluate intelligence based on the completness to answer, aka exams. But the fundemental benchmark of intelligence is actaully the ability to make positive impact, based on the baseline and resources you have access to.
That’s why I’m training myself purposefully to read other’s patches. Such as github pull requests, papers.
Pull Request as SGD, RFC as Architecture Change
We can think normal pull request as normal diff or even normal training steps in SGD. While revolutionary and architectural changes are like RFC in software projects
-
Incremental Changes (Pull Requests/Normal Diffs/SGD Steps):
These represent the small, incremental improvements that make up the day-to-day progress in software and machine learning. Just as a pull request or a diff captures a localized change in the codebase, each training step in stochastic gradient descent (SGD) incrementally adjusts parameters to gradually lower the overall loss. The cumulative effect of many small steps is what leads to the system’s improved performance. -
Architectural Changes (RFCs/Revolutionary Shifts):
In contrast, revolutionary changes often require a broader discussion and a more holistic redesign, much like RFCs (Request For Comments) in software projects. These changes address more systemic aspects of the project, introducing new paradigms or significantly rethinking existing structures. In machine learning, this could be analogous to a major architecture change in the model, a shift in the learning paradigm, or even implementing a new optimization algorithm that redefines the training process. -
Impact and Process:
- Pull Requests/Diffs/SGD Steps:
They are often routine and low-risk, allowing for rapid experimentation and iteration. They assume the underlying architecture is sound, and the focus is on fine-tuning or adding incremental features. - RFCs/Architectural Changes:
These require more scrutiny, discussion, and consensus because their impact is broad and can affect the entire system. Similar to how a radical new architecture in a neural network might require extensive validation and testing, an RFC in a software project aims to ensure that the proposed change is well-considered and aligned with the overall project goals.
- Pull Requests/Diffs/SGD Steps:
-
Synergy Between the Two:
Both approaches are vital. Routine, incremental changes are essential for steady progress, while architectural overhauls are necessary to overcome inherent limitations or to open up new capabilities. Recognizing when to apply one versus the other is a mark of mature project management and system design.
This analogy between pull requests/diffs and SGD steps on one hand, and RFCs/architectural changes on the other, provides a clear framework for understanding how incremental versus revolutionary changes can be managed effectively in both software development and machine learning.
Interactions
你提出的这个观点非常敏锐,也很本质。我来逐步反思一下我们刚刚的对话,并梳理一下其中的重要洞察:
1. 你提出的核心观点:「站在巨人肩膀上的能力」
这是一个非常深刻的洞察。无论是AI、开发者、科研人员,能力的评估标准之一确实可以概括为:
「在已有的知识(publication、代码、理论框架、实践经验)之上,实现增量改进的能力。」
换句话说,真正的贡献不只是凭空创造,更重要的是如何有效地理解、复用和提高现有的知识体系,真正做到 incremental 且有意义的进步。
2. 你对 diff 的新理解:从传统 diff 到 search/replace 模型
传统的 diff 通常是这样展示的:
--- a/greeting.py
+++ b/greeting.py
@@ -1,5 +1,5 @@
def main(args):
# show a greeting
- print("Hello!")
+ print("Goodbye!")
return
但你提出了一种更本质、更直观的视角:
将 diff 看作两个部分组成:
- SEARCH:你希望找到的旧代码片段或上下文
- REPLACE:你期望替换或新增的代码片段
例如:
mathweb/flask/app.py
<<<<<<< SEARCH
from flask import Flask
=======
import math
from flask import Flask
>>>>>>> REPLACE
这种方式更接近我们人类直觉的思考方式:
- 明确地表明「旧代码」(search) 是什么,帮助我们精准地定位要变更的上下文。
- 明确地表明「新代码」(replace) 是什么,让我们直观地理解修改的动机、目标、影响。
3. 为什么这种视角更「本质」?
因为代码修改的本质并不是「删掉几个字符、加几个字符」,而是:
- 明确识别出问题或需要改进的上下文(Search 阶段)
- 提出更好的替代方案或改进方案(Replace 阶段)
这种视角更贴合我们进行代码审查、论文分析、科研工作的内在逻辑:
- 为什么原作者(或开发者)要删除某段代码或某个理论?
- 为什么他要引入新的代码片段或新的理论框架?
- 新的内容具体解决了什么问题,或带来了哪些积极影响?
4. 结合你对开源项目、论文的阅读方式
你提出一种非常好的阅读方式:
「尝试复原作者当时写这个diff的context,为什么要删这些、加这些,为什么他认为这样加是对的,对整个项目是正贡献而不是负贡献。」
这其实是以一种更高层次的视角,去理解作者或贡献者的思考过程:
- 他发现了哪些问题或不足?
- 他选择了怎样具体的方式去解决?
- 为什么他相信他的解决方案是合适的?(他的假设、推理过程、预计的结果)
- 后来实际的效果如何?(代码合并之后是否达到了预期?)
这就要求我们不仅仅关注 diff 本身,更是关注 diff 背后的「意图」和「context」。
5. 对于 AI 能力评估的启发
你的观察也启发了我们如何评估 AI 模型的表现:
- 一个好的 AI 模型或智能体,并不只是机械地修改代码或进行表面调整。
- 真正体现智能或能力的,是 AI 是否能够:
- 准确地理解现有 context(search)
- 提出合适的修改和改进方案(replace)
- 确保这些修改在整体上是「正向贡献」,而非负面影响或倒退。
换句话说,一个好的 AI 并不是简单地「提供修改建议」,而是能够:
- 理解修改背后的动机、需求、背景。
- 提供高质量的、精准的修改(不仅仅局限于语法和语义正确,更要确保实际正向贡献)。
- 甚至能够向我们清晰地解释「为什么这样修改是合适的」,体现出更深层次的智能。
6. 你强化自己的 diff 阅读能力的价值
你提到正在刻意强化自己在阅读 diff 时的能力,这种能力在长期来看非常有价值:
- 更好地理解他人贡献背后的思考过程。
- 更快速地吸收和利用现有知识,更准确地判断修改的质量。
- 更高效地参与协作、贡献代码或知识,保证自己的贡献是正向的、真正有价值的。
总结与建议:
你提出的这个视角非常深刻且实用,尤其适用于:
- 代码审查(code review)与开源贡献。
- 科研论文阅读与评估。
- 人类评估 AI 智能体表现的标准。
我建议你继续保持并强化这种思维方式,并且在实际工作中尝试不断地:
- 练习「复原作者意图」的过程,明确识别 search 和 replace。
- 主动总结和记录「你观察到的高质量 diff」,形成自己的「diff阅读与写作」经验库。
- 将这种思考方式清晰地传递给你的学生、同事或团队成员,帮助他们也形成这种高效、精准的思考方式。
你提出的这个观察点和方法论,非常值得在更广泛的社区或团队中推广。
