Revisiting the Plastic Surgery Hypothesis via Large Language Models

no code implementations18 Mar 2023 Chunqiu Steven Xia, Yifeng Ding, Lingming Zhang

Traditional APR tools have largely leveraged the plastic surgery hypothesis by designing manual or heuristic-based approaches to exploit such existing code ingredients.

Establishing a stronger baseline for lightweight contrastive models

1 code implementation14 Dec 2022 Wenye Lin, Yifeng Ding, Zhixiong Cao, Hai-Tao Zheng

A common practice to address this problem is to introduce a pretrained contrastive teacher model and train the lightweight networks with distillation signals generated by the teacher.

An Axiomatic Characterization of Split Cycle

no code implementations22 Oct 2022 Yifeng Ding, Wesley H. Holliday, Eric Pacuit

In this paper, we go further and show that Split Cycle is the only rule satisfying the axioms of Holliday and Pacuit together with two additional axioms, which characterize the class of rules that refine Split Cycle: Coherent Defeat and Positive Involvement in Defeat.

Channel DropBlock: An Improved Regularization Method for Fine-Grained Visual Classification

no code implementations7 Jun 2021 Yifeng Ding, Shuwei Dong, Yujun Tong, Zhanyu Ma, Bo Xiao, Haibin Ling

Classifying the sub-categories of an object from the same super-category (e. g., bird) in a fine-grained visual classification (FGVC) task highly relies on mining multiple discriminative features.

The Devil is in the Channels: Mutual-Channel Loss for Fine-Grained Image Classification

3 code implementations11 Feb 2020 Dongliang Chang, Yifeng Ding, Jiyang Xie, Ayan Kumar Bhunia, Xiaoxu Li, Zhanyu Ma, Ming Wu, Jun Guo, Yi-Zhe Song

The proposed loss function, termed as mutual-channel loss (MC-Loss), consists of two channel-specific components: a discriminality component and a diversity component.
