Towards Attributions of Input Variables in a Coalition

no code implementations23 Sep 2023 Xinhao Zheng, Huiqi Deng, Bo Fan, Quanshi Zhang

This paper aims to develop a new attribution method to explain the conflict between individual variables' attributions and their coalition's attribution from a fully new perspective.

Mitigating Shortcuts in Language Models with Soft Label Encoding

no code implementations17 Sep 2023 Zirui He, Huiqi Deng, Haiyan Zhao, Ninghao Liu, Mengnan Du

Recent research has shown that large language models rely on spurious correlations in the data for natural language understanding (NLU) tasks.

Natural Language Understanding Out-of-Distribution Generalization

Explainability for Large Language Models: A Survey

no code implementations2 Sep 2023 Haiyan Zhao, Hanjie Chen, Fan Yang, Ninghao Liu, Huiqi Deng, Hengyi Cai, Shuaiqiang Wang, Dawei Yin, Mengnan Du

For each paradigm, we summarize the goals and dominant approaches for generating local explanations of individual predictions and global explanations of overall model knowledge.

Understanding and Unifying Fourteen Attribution Methods with Taylor Interactions

no code implementations2 Mar 2023 Huiqi Deng, Na Zou, Mengnan Du, Weifu Chen, Guocan Feng, Ziwei Yang, Zheyang Li, Quanshi Zhang

Various attribution methods have been developed to explain deep neural networks (DNNs) by inferring the attribution/importance/contribution score of each input variable to the final output.

Bayesian Neural Networks Avoid Encoding Complex and Perturbation-Sensitive Concepts

1 code implementation25 Feb 2023 Qihan Ren, Huiqi Deng, Yunuo Chen, Siyu Lou, Quanshi Zhang

In this paper, we focus on mean-field variational Bayesian Neural Networks (BNNs) and explore the representation capacity of such BNNs by investigating which types of concepts are less likely to be encoded by the BNN.

Concept-Level Explanation for the Generalization of a DNN

no code implementations25 Feb 2023 Huilin Zhou, Hao Zhang, Huiqi Deng, Dongrui Liu, Wen Shen, Shih-Han Chan, Quanshi Zhang

Therefore, in this paper, we investigate the generalization power of each interactive concept, and we use the generalization power of different interactive concepts to explain the generalization power of the entire DNN.

Trap of Feature Diversity in the Learning of MLPs

no code implementations2 Dec 2021 Dongrui Liu, Shaobo Wang, Jie Ren, Kangrui Wang, Sheng Yin, Huiqi Deng, Quanshi Zhang

In this paper, we focus on a typical two-phase phenomenon in the learning of multi-layer perceptrons (MLPs), and we aim to explain the reason for the decrease of feature diversity in the first phase.

Discovering and Explaining the Representation Bottleneck of DNNs

1 code implementation ICLR 2022 Huiqi Deng, Qihan Ren, Hao Zhang, Quanshi Zhang

This paper explores the bottleneck of feature representations of deep neural networks (DNNs), from the perspective of the complexity of interactions between input variables encoded in DNNs.

A General Taylor Framework for Unifying and Revisiting Attribution Methods

no code implementations28 May 2021 Huiqi Deng, Na Zou, Mengnan Du, Weifu Chen, Guocan Feng, Xia Hu

However, the attribution problem has not been well-defined, which lacks a unified guideline to the contribution assignment process.

Mutual Information Preserving Back-propagation: Learn to Invert for Faithful Attribution

no code implementations14 Apr 2021 Huiqi Deng, Na Zou, Weifu Chen, Guocan Feng, Mengnan Du, Xia Hu

The basic idea is to learn a source signal by back-propagation such that the mutual information between input and output should be as much as possible preserved in the mutual information between input and the source signal.

Decision Making

A Unified Taylor Framework for Revisiting Attribution Methods

no code implementations21 Aug 2020 Huiqi Deng, Na Zou, Mengnan Du, Weifu Chen, Guocan Feng, Xia Hu

Attribution methods have been developed to understand the decision-making process of machine learning models, especially deep neural networks, by assigning importance scores to individual features.
