Improving deep neural networks using softplus units

2015

Recently, DNNs have achieved great improvement for acoustic modeling in speech recognition tasks. However, it is difficult to train the models well when the depth grows. One main reason is that when training DNNs with …

Multi-task learning deep neural networks for speech feature denoising

2015

Traditional automatic speech recognition (ASR) systems usually\nget a sharp performance drop when noise presents in\nspeech. To make a robust ASR, we introduce a new model using\nthe multi-task learning deep neural networks (MTL-DNN)\nto solve the speech …
