class ov::pass::LSTMCellDecomposition

Overview

LSTMCellDecomposition transformation decomposes LSTMCell layer with inputs X, H, C, W, R, B to Add, Split, MatMul, Multiply ops according to the formula: (.) - Denotes element-wise multiplication. More…

Detailed Documentation

LSTMCellDecomposition transformation decomposes LSTMCell layer with inputs X, H, C, W, R, B to Add, Split, MatMul, Multiply ops according to the formula: (.) - Denotes element-wise multiplication.

• Denotes dot product. f, g, h - are activation functions.

it = f(Xt*(Wi^T) + Ht-1*(Ri^T) + Wbi + Rbi) ft = f(Xt*(Wf^T) + Ht-1*(Rf^T) + Wbf + Rbf) ct = g(Xt*(Wc^T) + Ht-1*(Rc^T) + Wbc + Rbc) ot = f(Xt*(Wo^T) + Ht-1*(Ro^T) + Wbo + Rbo) Ct = ft (.) Ct-1 + it (.) ct Ht = ot (.) h(Ct)
