Advancing Acoustic-to-Word CTC Model with Attention and Mixed-Units

Amit Das, Jinyu Li, Guoli Ye +2

The acoustic-to-word model based on the Connectionist Temporal Classification (CTC) criterion is a natural end-to-end (E2E) system directly targeting word as output unit. Two issue…

Compact stars in gravity

Amit Das, Farook Rahaman, B. K. Guha +1

In the present paper we generate a set of solutions describing the interior of a compact star under theory of gravity which admits conformal motion. We consider the equati…

RECOM: A Validity Discrimination Tradeoff in Automatic Metrics for Open Ended Reddit Question Answering

Pushwitha Krishnappa, Amit Das, Vinija Jain +2

Automatic metrics are the default for evaluating LLM-generated text, yet a metric is quietly asked to do two jobs: tell genuine content alignment from surface coincidence (validity…

Nonclassicality and sub-Planck structures of photon subtracted compass states

Amit Das, Sobhan Sounda

We discuss the nonclassical properties of photon-subtracted compass states (PSCS). Nonclassical behavior is studied using various parameters like the Wigner function, squeezing, an…

High-Accuracy and Low-Latency Speech Recognition with Two-Head Contextual Layer Trajectory LSTM Model

Jinyu Li, Rui Zhao, Eric Sun +4

While the community keeps promoting end-to-end models over conventional hybrid models, which usually are long short-term memory (LSTM) models trained with a cross entropy criterion…

Advancing Connectionist Temporal Classification With Attention Modeling

Amit Das, Jinyu Li, Rui Zhao +1

In this study, we propose advancing all-neural speech recognition by directly incorporating attention modeling within the Connectionist Temporal Classification (CTC) framework. In…
