RFA selected set of putative functionally relevant host discriminating amino acids in H1N1 influenza HA compared with those found with the Adaboost algorithm.

1The receptor binding domain refers to positions 114 through 268 of the HA segment.2The antigenic sites considered here are those defined as such in [60].3The Adaboost algorithm as implemented in [33].1. 受体结合域（Receptor Binding Domain）对应HA段（Hemagglutinin）的114至268位位点。 2. 本文所涉及的抗原表位（Antigenic Sites）均为文献[60]中所定义的此类抗原位点。 3. 本文所采用的Adaboost算法，即文献[33]中所实现的算法版本。
