Preference-CFR: Beyond Nash Equilibrium for Better Game Strategies

ICML 2025poster

Artificial intelligence (AI) has surpassed top human players in a variety of games. In imperfect information games, these achievements have primarily been driven by Counterfactual Regret Minimization (CFR) and its variants for computing Nash equilibrium. However, most existing research has focused o…

Accelerating Nash Equilibrium Convergence in Monte Carlo Settings Through Counterfactual Value Based Fictitious Play

NeurIPS 2024poster

Counterfactual Regret Minimization (CFR) and its variants are widely recognized as effective algorithms for solving extensive-form imperfect information games. Recently, many improvements have been focused on enhancing the convergence speed of the CFR algorithm. However, most of these variants are n…

Recouple Event Field via Probabilistic Bias for Event Extraction

ICASSP 2023accepted

Event Extraction (EE), aiming to identify and classify event triggers and arguments from event mentions, has benefited from pre-trained language models (PLMs). However, existing PLM-based methods ignore the information of trigger/argument fields, which is crucial for understanding event schemas. To…

Energy Alignment for Bias Rectification in Class Incremental Learning

ICASSP 2022accepted

In class incremental learning (CIL), models are expected to be able to learn new categories continuously. However, the standard DNNs suffer from catastrophic forgetting. Recent studies show class imbalance is an essential factor that causes catastrophic forgetting in CIL. In this paper, from the per…

Multi-stage Distillation Framework for Cross-Lingual Semantic Similarity Matching

NAACL 2022findings

Previous studies have proved that cross-lingual knowledge distillation can significantly improve the performance of pre-trained models for cross-lingual similarity matching tasks. However, the student model needs to be large in this operation. Otherwise, its performance will drop sharply, thus makin…

Stacked Acoustic-and-Textual Encoding: Integrating the Pre-trained Models into Speech Translation Encoders

ACL 2021long

Encoder pre-training is promising in end-to-end Speech Translation (ST), given the fact that speech-to-translation data is scarce. But ST encoders are not simple instances of Automatic Speech Recognition (ASR) or Machine Translation (MT) encoders. For example, we find that ASR encoders lack the glob…

Dynamic Curriculum Learning for Low-Resource Neural Machine Translation

COLING 2020main

Large amounts of data has made neural machine translation (NMT) a big success in recent years. But it is still a challenge if we train these models on small-scale corpora. In this case, the way of using data appears to be more important. Here, we investigate the effective use of training data for lo…
