ANECDOTE

Kaggle Humility

  • Jean-Francois Puget, a PhD in machine learning, initially assumed he would easily top Kaggle competitions.
  • However, his ranking dropped significantly after the private dataset results, humbling him and prompting practical learning.
ADVICE

Scientific Approach to Machine Learning

  • Approach machine learning with a scientific method, treating every idea as an experiment.
  • Evaluate model modifications rigorously through cross-validation, comparing results against a reliable baseline.
ADVICE

Experimentation and Overfitting

  • Test your assumptions and modifications consistently.
  • Avoid overfitting to cross-validation splits and the public leaderboard; use it conservatively.
