Deconfounding age impacts

This is a project done while interning at Winterlight Labs. We identify the problem of age being confounded into dementia detection with linguistic features, propose to use fair representation learning to address it, and propose to evaluate with a modified equalized odd score.
On two datasets, DementiaBank and Famous People, our best methods outperform traditional statistical adjustments (residualization and inverse probability weighting), and are comparable to the theoretical upper bound.

Familiarizing with bash

This blog contains some notes for using bash command. I’m writing them here in an “aid-sheet” style. This could also be a concise, elementary tutorial into bash. I’ll group them into following sections.
Survival

  • File system navigation (cd, ls, cat, du, df)
  • Playing around with variables

Remote working

  • Connect to remote computer (ssh, sftp, wget, curl)
  • Compress / uncompress files (dpkg, tar, zip)
  • Run programs remotely (chmod, nohup, &, &&)

Processing data

  • For loop, sed, find, grep, piping

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 illusion

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.
