標准LSTM：
與標准LSTM相比，Kaldi的fastlstm對相同或類似的矩陣運算進行了合並。
# Component specific to 'projected' LSTM (LSTMP), contains both recurrent and non-recurrent projections
fastlstm.W_rp, fast lstm Weight recurrent projected
fastlstm.W_all, fast lstm Weight all
fastlstm.rp, fast lstm recurrent projected
同時包含了對循環與非循環的向量的投影
即將1024維輸入投影為循環的向量維數（如256）與非循環的向量維數（如512）
fastlstm.c, fast lstm cell
fastlstm.m, fast lstm memory
fastlstm.r, fast lstm recurrent
fastlstm.cr_trunc, fast lstm cell recurrent truncate
用於向量的截斷，截斷為
fastlstm.c_trunc, fast lstm cell truncated
fastlstm.r_trunc, fast lstm recurrent truncated
