Table 1 Comparison between F measure while using Blocks and k-length subsequences

From: A method for probabilistic mapping between protein structure and function taxonomies through cross training

Class F (subsequences) F (Blocks)
Small proteins .78 .73
Globin like .71 .684
NAD P binding Rossmann fold domains .54 .537
  1. Comparison of F-measure using k-length overlapping subsequences of length (k) equal to 4 and blocks as features. In the case of using blocks as features, F-measure was found to be only slightly lower for all the classes, while the size of feature set was many times smaller.
