To be done:

# SuiteSparse lib
# decrease the hidden layer from 4-2
# Test accuracy on large data set

GPU & CPU merge

1. Hold

Confidence estimation

1. DNN-based confidence estimation for decoding and alignment is done. The intuitive testing seems ok.

To DO:

1. Large scale test.
2. CI Phone-based full path confidence estimation.

FST sub-graph integration

1. Coding finished.
2. Debuging and Test next week.

Embedded progress

1. Graph search costs a lot when the graph is large. Need to improve the indexing performance.
2. Need to integrate the Kaldi FE with pocket-sphinx decoder.
