ICASSP 2020accepted

User interactions with personal assistants like Alexa, Google Home and Siri are typically initiated by a wake term or wake-word. Several personal assistants feature "follow-up" modes that allow users to make additional interactions without the need of a wakeword. For the system to only respond when…

Towards Better Confidence Estimation for Neural Models

Vishal Thanvantri Vasudevan, Abhinav Sethy, Alireza Roshan Ghias

ICASSP 2019accepted

In this work we focus on confidence modeling for neural network based text classification and sequence to sequence models in the context of Natural Language Understanding (NLU) tasks. For most applications, the confidence of a neural network model in it's output is computed as a function of the post…
