Accurate KV Cache Quantization with Outlier Tokens Tracing

ACL 2025long

The impressive capabilities of Large Language Models (LLMs) come at the cost of substantial computational resources during deployment. While KV Cache can significantly reduce recomputation during inference, it also introduces additional memory overhead. KV Cache quantization presents a promising sol…

Alignment-Augmented Speculative Decoding with Alignment Sampling and Conditional Verification

EMNLP 2025

Recent works have revealed the great potential of speculative decoding in accelerating the autoregressive generation process of large language models. The success of these methods relies on the alignment between draft candidates and the sampled outputs of the target model. Existing methods mainly ac

Beware of Calibration Data for Pruning Large Language Models

ICLR 2025poster

As large language models (LLMs) are widely applied across various fields, model compression has become increasingly crucial for reducing costs and improving inference efficiency. Post-training pruning is a promising method that does not require resource-intensive iterative training and only needs a…

Multi-Branch Self-Drafting for LLM Inference Acceleration

AAAI 2025technical

The autoregressive decoding paradigm endows large language models (LLMs) with superior language generation capabilities; however, its step-by-step decoding process inherently limits decoding speed. To mitigate these constraints, the prevalent “draft and validation” strategy enables parallel validati…

Adaptive Feature-based Low-Rank Compression of Large Language Models via Bayesian Optimization

EMNLP 2024finding

In recent years, large language models (LLMs) have driven advances in natural language processing. Still, their growing scale has increased the computational burden, necessitating a balance between efficiency and performance. Low-rank compression, a promising technique, reduces non-essential paramet…

Are Bert Family Good Instruction Followers? A Study on Their Potential And Limitations

ICLR 2024poster

Language modeling at scale has proven very effective and brought unprecedented success to natural language models. Many typical representatives, especially decoder-only models, e.g., BLOOM and LLaMA, and encoder-decoder models, e.g., Flan-T5 and AlexaTM, have exhibited incredible instruction-followi…

AraMUS: Pushing the Limits of Data and Model Scale for Arabic Natural Language Processing

ACL 2023findings

Developing monolingual large Pre-trained Language Models (PLMs) is shown to be very successful in handling different tasks in Natural Language Processing (NLP). In this work, we present AraMUS, the largest Arabic PLM with 11B parameters trained on 529GB of high-quality Arabic textual data. AraMUS ac…

Fast and Accurate End-to-End Span-based Semantic Role Labeling as Word-based Graph Parsing

COLING 2022main

This paper proposes to cast end-to-end span-based SRL as a word-based graph parsing task. The major challenge is how to represent spans at the word level. Borrowing ideas from research on Chinese word segmentation and named entity recognition, we propose and compare four different schemata of graph…

MuCPAD: A Multi-Domain Chinese Predicate-Argument Dataset

NAACL 2022long

During the past decade, neural network models have made tremendous progress on in-domain semantic role labeling (SRL). However, performance drops dramatically under the out-of-domain setting. In order to facilitate research on cross-domain SRL, this paper presents MuCPAD, a multi-domain Chinese pred…

Semantic Role Labeling as Dependency Parsing: Exploring Latent Tree Structures inside Arguments

COLING 2022main

Semantic role labeling (SRL) is a fundamental yet challenging task in the NLP community. Recent works of SRL mainly fall into two lines: 1) BIO-based; 2) span-based. Despite ubiquity, they share some intrinsic drawbacks of not considering internal argument structures, potentially hindering the model…

A Unified Span-Based Approach for Opinion Mining with Syntactic Constituents

NAACL 2021long

Fine-grained opinion mining (OM) has achieved increasing attraction in the natural language processing (NLP) community, which aims to find the opinion structures of “Who expressed what opinions towards what” in one sentence. In this work, motivated by its span-based representations of opinion expres…

Semantic Role Labeling with Heterogeneous Syntactic Knowledge

COLING 2020main

Recently, due to the interplay between syntax and semantics, incorporating syntactic knowledge into neural semantic role labeling (SRL) has achieved much attention. Most of the previous syntax-aware SRL works focus on explicitly modeling homogeneous syntactic knowledge over tree outputs. In this wor…
