InforMask: Unsupervised Informative Masking for Language Model Pretraining

EMNLP 2022main

Masked language modeling is widely used for pretraining large language models for natural language understanding (NLU). However, random masking is suboptimal, allocating an equal masking rate for all tokens. In this paper, we propose InforMask, a new unsupervised masking strategy for training masked…

Bangla Voice Command Recognition in end-to-end System Using Topic Modeling based Contextual Rescoring

ICASSP 2020accepted

In this work, we perform contextual rescoring using multi-label topic modeling to improve the performance of an End-to-End Bangla voice command recognition system. We use a hybrid of Connectionist Temporal Classification (CTC) and Attention mechanism in our End-to-End architecture. We use Recurrent…
