Cross-Corpus Speech Emotion Recognition Based on Multiple Kernel Learning of Joint Sample and Feature Matching

الملخص EN

Cross-corpus speech emotion recognition, which learns an accurate classifier for new test data using old and labeled training data, has shown promising value in speech emotion recognition research.

Most previous works have explored two learning strategies independently for cross-corpus speech emotion recognition: feature matching and sample reweighting.

In this paper, we show that both strategies are important and inevitable when the distribution difference is substantially large for training and test data.

We therefore put forward a novel multiple kernel learning of joint sample and feature matching (JSFM-MKL) to model them in a unified optimization problem.

Experimental results demonstrate that the proposed JSFM-MKL outperforms the competitive algorithms for cross-corpus speech emotion recognition.
