Parameters Parameters
---------- ----------
var: shape, comment var
W: (iBlocks, oBlocks, iSize, oSize), weight matrix Shape, comment.
h: (batch, iWin, iSize), input from lower layer (sparse) W
inputIdx: (batch, iWin), indexes of the input blocks (iBlocks, oBlocks, iSize, oSize), weight matrix.
b: (oBlocks, oSize), bias vector h
outputIdx: (batch, oWin), indexes of the output blocks (batch, iWin, iSize), input from lower layer (sparse).
