Weekly Summary

1. Search for discriminative features for the cohort-based SVM classifier.

We select orignal score, t-norm score, relative ranking, cohort-score, cohort-subtraction-score(delta-score).

2. Verify the discriminative ability of the relative ranking and delta-score.

Results show that these two features can be applied for SVM classification.

The best performance is obtained when SVM input feature is made up of orignal score, t-norm score, relative ranking and delta-score.

3. Help Pro.Zheng collect digit speech.

Next Week
