Project description

This is the commandline trainer for Fathom, which itself is a supervised-learning system for recognizing parts of web pages. It also includes other commandline tools for ruleset development, like fathom-unzip, fathom-pick, and fathom-list. See docs for the trainer here.

  • Add 95% CI for per-page training accuracy.

  • Add validation-guided early stopping.

  • Revise per-page accuracy calculation and display.
