Speech Processing

AM development

Environment

• grid-12 GPU is transferred to grid-18
• buy a 970 GPU

RNN AM

• train monophone RNN --zhiyuan

• decode using 5-gram
• the train method of batch

• train using large dataset--mengyuan
• write code to tune learning rate --zhiyong

• has completed Nestrov/Adagrad/Adagrad-max
• has unstable phenomenon
• completed adam,adadeta,adam-max --Xiangyu,Zhiyong
• reproduce PSO --Xiangyu

Mic-Array

• hold
• compute EER with kaldi

Data selection unsupervised learning

• hold
• acoustic feature based submodular using Pingan dataset --zhiyong
• write code to speed up --zhiyong

RNN-DAE(Deep based Auto-Encode-RNN)

• RNN-DAE has worse performance than DNN-DAE because training dataset is small
• extract real room impulse to generate WSJ reverberation data, and then train RNN-DAE

Ivector&Dvector based ASR

• Cluster the speakers to speaker-cluster

• hold

• dark knowledge

• has much worse performance than baseline (EER: base 29% dark knowledge 48%)

• RNN ivector

• hold

• binary ivector done
• metric learning

language vector

• hold
• write a paper--zhiyuan
• RNN language vector

• hold

multi-GPU=

• multi-stream training --Sheng Su

• two GPUs work well, but four GPUs divergent

• solve the problem of buffer-- Sheng Su

Neutral picture style transfer

• reproduced the result of the paper "A neutral algorithm of artistic style" --Zhiyuan, Xuewei
• while subject to the GPU's memory, limited to inception net with sgd optimizer (VGG network with the default L-BFGS optimizer consumes very much memory, which is better)
