EM-Network: Oracle Guided Self-distillation for Sequence Learning

ICML 2023poster

We introduce EM-Network, a novel self-distillation approach that effectively leverages target information for supervised sequence-to-sequence (seq2seq) learning. In contrast to conventional methods, it is trained with oracle guidance, which is derived from the target sequence. Since the oracle guida…

Robust Front-End for Multi-Channel ASR using Flow-Based Density Estimation

IJCAI 2020poster

For multi-channel speech recognition, speech enhancement techniques such as denoising or dereverberation are conventionally applied as a front-end processor. Deep learning-based front-ends using such techniques require aligned clean and noisy speech pairs which are generally obtained via data simula…

SoftFlow: Probabilistic Framework for Normalizing Flow on Manifolds

NeurIPS 2020poster

Flow-based generative models are composed of invertible transformations between two random variables of the same dimension. Therefore, flow-based models cannot be adequately trained if the dimension of the data distribution does not match that of the underlying target distribution. In this paper, we…
