Weekly Summary

1. Go on my deep speaker embedding tasks:

1). knowledge transfer for i-vector -- working with Zhiyuan Zhang.

Finish modifying the nnet-training objective function (nnet-train-perutt-persoft and nnet-train-perutt-persoft-average).

Finish DNN training process.

2). Start my new task: metric learning using deep neural networks.

Using 'Wangd dataset' to re-compare the non-linear(two layers NN) and linear metric learning.

On processing.

2. Re-embedding i-vector with lower dimension 200 and lda 100.

Note that for the process of T-matrix training, Num_threads should be set 1.

3. Complete my thesis proposal.

4. Write paper on 'Discriminative Score Feature Selection for Speaker Verification'.

Next Week

1. Go on the task 1.
