1\use fratio calculated from time-varying database to extract features and test on SRE08 database.
2\test mlp methods which input vetor is defined as the concatenate of two lda vectors from different sessions, and output is defined as '1 0' when input two lda vectors extract from different persons, '0 1' when input two lda vectors extract from same persons.
3\test sampling methods for lda and plda.
1\to read dnn papers, to read fratio paper.
2\to proceed with mlp test.
