Scikit-learn:. 6 semi-supervised learning model

First, the label propagation algorithm

scikit-learn There are two class implements the label propagation algorithm:

• LabelPropagation: Iterative process:

  • Execution tag propagation: ^ {$ F. <T +. 1>} = {the PF ^ <. 1 + T>} $ .
  • Reset $ F $ tab sample tag: $ f_L ^ {<T +. 1>} = y_L $ , $ where $ f_L represents $ F $ front $ $ L line.

• LabelSpreading: Iterative process: $ F ^ {<t + 1>} = \ alpha SF ^ {<t>} + (1- \ alpha) Y $
