When Pearl meets Kant

This blog contains some random thoughts about Pearl’s The Book of Why Kant’s Critique of Pure Reason. The former is about probability reasoning, and the latter about metaphysics. Nevertheless many ideas fit into each other.

  • Correlation vs. causation
  • The structure of reasoning
  • Deconfounding as transcendental illution

Software lessons from distributed systems

This semester I worked in the first non-trivial-size software engineering course project, ECE419, where a team of three students wrote a distributed key-value storage service using Java. Reflecting on the team work, there are several things I found important for software engineering teams:

  1. Remember that we make mistakes.
  2. Be open to different expectations.
  3. Workload balancing remains an open question.

Thoughts about the free lunch

This post starts when I was reviewing the no free lunch theorem in machine learning. A machine learning model being able to predict with high accuracy from unseen data should have knowledge about the data. Then what is knowledge? I started to have the feeling that knowledge should be defined in a broader sense than what it is done in (intro) epistemology textbooks. Namely, it should be closely related to the creation of intelligent systems, which might be more important than defining what knowledge is in human languages.

  • A brief overview about the no free lunch theorem
  • Does learning something indicate having knowledge over it?
  • Gödel’s idea…?
  • What should we do then? (If knowledge is nothing, then what does the hard tasks at schools make sense?)
