Prediction of GPCR-Ligand Binding Using Machine Learning Algorithms

Algorithm 1

Algorithm for generating negative samples.
For each GPCR X from positive samples,
  Step  1. Randomly select GPCR Y from one of the positive samples;
  Step  2. If and have common binding ligand(s), go to Step  1.
     Otherwise, randomly select one ligand among ligands that bind to ,
     and make a negative sample with “-
  Step  3. If negative samples already have “X-Z”, go to Step  1.
