Fusion Long-Short Term Memory (LSTM) Operator.
This operator fuse the X into LSTM, more details can refer to LSTM op.
Attention Long-Short Term Memory (LSTM) Operator.
Attention part:
concat( x(seqlen * M), expand( cell_t-1(1,D) ) ) => tmp(seqlen*(M+D))
tmp(seqlen*(M+D)) * fc((M+D)*1) => fcout(seqlen*1) with bias, relu

dotmul and sum pool ( fcout(seqlen*1), x(seqlen * M) ) => lstm_x_t(1, M)
LSTM part:
