Boosting Model Resilience via Implicit Adversarial Data Augmentation

no code implementations25 Apr 2024 Xiaoling Zhou, Wei Ye, Zhemg Lee, Rui Xie, Shikun Zhang

This insight leads us to develop a meta-learning-based framework for optimizing classifiers with this novel loss, introducing the effects of augmentation while bypassing the explicit augmentation process.

Implicit Counterfactual Data Augmentation for Deep Neural Networks

no code implementations26 Apr 2023 Xiaoling Zhou, Ou wu

Machine-learning models are prone to capturing the spurious correlations between non-causal attributes and classes, with counterfactual data augmentation being a promising direction for breaking these spurious associations.

Combining Adversaries with Anti-adversaries in Training

no code implementations25 Apr 2023 Xiaoling Zhou, Nan Yang, Ou wu

On the basis of our theoretical findings, a more general learning objective that combines adversaries and anti-adversaries with varied bounds on each training sample is presented.

Understanding Difficulty-based Sample Weighting with a Universal Difficulty Measure

no code implementations12 Jan 2023 Xiaoling Zhou, Ou wu, Weiyao Zhu, Ziyang Liang

In this study, we theoretically prove that the generalization error of a sample can be used as a universal difficulty measure.

Which Samples Should be Learned First: Easy or Hard?

no code implementations11 Oct 2021 Xiaoling Zhou, Ou wu

Factors including the distribution of samples' learning difficulties and the validation data determine which samples should be learned first in a learning task.

WHICH SAMPLES SHOULD BE LEARNED FIRST:EASY OR HARD?

no code implementations29 Sep 2021 Xiaoling Zhou, Ou wu

Second, a flexible weighting scheme is proposed to overcome the defects of existing schemes.

A Recurrent Model for Collective Entity Linking with Adaptive Features

1 code implementation AAAI 2020 Xiaoling Zhou, Yukai Miao, Wei Wang, Jianbin Qin

Traditional machine learning based methods for NED were outperformed and made obsolete by the state-of-the-art deep learning based models.

Antonym-Synonym Classification Based on New Sub-space Embeddings

no code implementations13 Jun 2019 Muhammad Asif Ali, Yifang Sun, Xiaoling Zhou, Wei Wang, Xiang Zhao

We hypothesize that the pre-trained embeddings comprehend a blend of lexical-semantic information and we may distill the task-specific information using Distiller, a model proposed in this paper.
