However, most existing works in embodied dialog research focus on navigation and leave the localization task understudied.

Economic Forces in Stock Returns

no code implementations • 6 Jan 2024 • Yue Chen, Mohan Li

Driven by such motivation, we conduct an attribution analysis based on the general framework of their model to further prove the importance of the economic factors and identify the specific identity of significant factors.

Self-regularised Minimum Latency Training for Streaming Transformer-based Speech Recognition

no code implementations • 24 Apr 2023 • Mohan Li, Rama Doddipatla, Catalin Zorila

In previous works, latency was optimised by truncating the online attention weights based on the hard alignments obtained from conventional ASR models, without taking into account the potential loss of ASR accuracy.

End-to-end Speech Recognition with Adaptive Computation Steps

no code implementations • 30 Aug 2018 • Mohan Li, Min Liu, Masanori Hattori

In this paper, we present Adaptive Computation Steps (ACS) algo-rithm, which enables end-to-end speech recognition models to dy-namically decide how many frames should be processed to predict a linguistic output.
