Anthony Goldbloom from Kaggle Visits

  • Guy used random forests to win HIV competition. Word "random forests" is trademarked. Dude taught himself machine learning from watching youtube videos. Random forests are pretty robust to new data.
    • Used caret package in R to deal with random forests.
  • Kaggle splits test dataset into two, uses half for leaderboard.
  • Often score difference between winning model and second place is not statistically significant. So they award prizes to top few. Might impose restrictions on execution time of model.
