  1. Models trained on dataset2431 and testing performed with dataset2431, dataset579 and 10 × cross validation on dataset2431, features removed by increasing stringency of t-test of individual feature to activity from dataset2431.
  2. Feature numbers in parentheses are the average number of features in cross validations.
  3. Entries in bold are column maximums and are simply visual landmarks.
