Faster In-Context Learning for LLMs via N-Gram Trie Speculative Decoding

EMNLP 2025

As a crucial method in prompt engineering, In-Context Learning (ICL) enhances the generalization and knowledge utilization capabilities of Large Language Models (LLMs) (Dong et al., 2024). However, the lengthy retrieved contexts and limited token throughput in autoregressive models significantly con

Joint Automatic Speech Recognition And Structure Learning For Better Speech Understanding

ICASSP 2025accepted

Spoken language understanding (SLU) is a structure prediction task in the field of speech. Recently, many works on SLU that treat it as a sequence-to-sequence task have achieved great success. However, This method is not suitable for simultaneous speech recognition and understanding. In this paper,…

Hypergraph based Understanding for Document Semantic Entity Recognition

ACL 2024long

Semantic entity recognition is an important task in the field of visually-rich document understanding. It distinguishes the semantic types of text by analyzing the position relationship between text nodes and the relation between text content. The existing document understanding models mainly focus…

VHASR: A Multimodal Speech Recognition System With Vision Hotwords

EMNLP 2024main

The image-based multimodal automatic speech recognition (ASR) model enhances speech recognition performance by incorporating audio-related image. However, some works suggest that introducing image information to model does not help improving ASR performance. In this paper, we propose a novel approac…

Kullback-Leibler Divergence Frequency Warping Scale for Acoustic Scene Classification Using Convolutional Neural Network

ICASSP 2019accepted

Most of current best performing Acoustic Scene Classification (ASC) systems utilize Mel scale spectrograms with Convolutional Neural Networks (CNNs). Mel scale is a common way to suit frequency warping of human ears, with strict decreasing frequency resolution on low to high frequency range. However…
