Abstract(in English) | The emotion estimation by speech makes it possible to estimate with higher precision with the development of deep learning. However, most of the emotion estimation using deep learning is using supervised learning, and there is a problem that it is difficult to secure a large amount of data set used for learning. In addition, when the training data environment and the actual data environment are significantly different, it is considered as a problem that the accuracy of emotion estimation greatly deteriorates. Therefore, as an approach to solve both problems, in this research, smoothing of the generated emotion estimation model is performed using virtual adversal training (VAT), semi-teacher learning, and the robustness of the model Improvement was aimed. VAT attracts attention in machine learning as a method of smoothing a generation model by adding minute and intentional perturbation to training data in learning. We first showed improvement of robustness of model generated by setting hyperparameter in VAT by verification with single corpus and then performing evaluation experiment with cross corpus. |
