Combining Curriculum Learning and Knowledge Distillation for Dialogue Generation

no code implementations Findings (EMNLP) 2021 Qingqing Zhu, Xiuying Chen, Pengfei Wu, Junfei Liu, Dongyan Zhao

Hence, in this paper, we introduce a combination of curriculum learning and knowledge distillation for efficient dialogue generation models, where curriculum learning can help knowledge distillation from data and model aspects.

Parallel Decoding via Hidden Transfer for Lossless Large Language Model Acceleration

no code implementations18 Apr 2024 Pengfei Wu, Jiahao Liu, Zhuocheng Gong, Qifan Wang, Jinpeng Li, Jingang Wang, Xunliang Cai, Dongyan Zhao

In this paper, we propose a novel parallel decoding approach, namely \textit{hidden transfer}, which decodes multiple successive tokens simultaneously in a single forward pass.

LSTP: Language-guided Spatial-Temporal Prompt Learning for Long-form Video-Text Understanding

1 code implementation25 Feb 2024 Yuxuan Wang, Yueqian Wang, Pengfei Wu, Jianxin Liang, Dongyan Zhao, Zilong Zheng

Despite progress in video-language modeling, the computational challenge of interpreting long-form videos in response to task-specific linguistic queries persists, largely due to the complexity of high-dimensional video data and the misalignment between language and visual cues over space and time.

Underwater Sound Speed Profile Construction: A Review

no code implementations12 Oct 2023 Wei Huang, Jixuan Zhou, Fan Gao, Jiajun Lu, Sijia Li, Pengfei Wu, Junting Wang, Hao Zhang, Tianhe Xu

The proposal of SSP inversion method greatly improves the convenience and real--time performance, but the accuracy is not as good as the direct measurement method.

A Safe DRL Method for Fast Solution of Real-Time Optimal Power Flow

no code implementations7 Aug 2023 Pengfei Wu, Chen Chen, Dexiang Lai, Jian Zhong

Instead of integrating the constraint violation penalty with the reward function, its actor gradients are estimated by a Lagrange advantage function which is derived from two critic systems based on economic reward and violation cost.

Momentum Benefits Non-IID Federated Learning Simply and Provably

no code implementations28 Jun 2023 Ziheng Cheng, Xinmeng Huang, Pengfei Wu, Kun Yuan

When all clients participate in the training process, we demonstrate that incorporating momentum allows FedAvg to converge without relying on the assumption of bounded data heterogeneity even using a constant local learning rate.

FORTAP: Using Formulas for Numerical-Reasoning-Aware Table Pretraining

1 code implementation ACL 2022 Zhoujun Cheng, Haoyu Dong, Ran Jia, Pengfei Wu, Shi Han, Fan Cheng, Dongmei Zhang

In this paper, we find that the spreadsheet formula, which performs calculations on numerical values in tables, is naturally a strong supervision of numerical reasoning.

Learning Deep Representations by Mutual Information for Person Re-identification

no code implementations16 Aug 2019 Peng Chen, Tong Jia, Pengfei Wu, Jianjun Wu, Dongyue Chen

Most existing person re-identification (ReID) methods have good feature representations to distinguish pedestrians with deep convolutional neural network (CNN) and metric learning methods.
