MetaMix: Towards Corruption-Robust Continual Learning With Temporally Self-Adaptive Data Transformation

no code implementations CVPR 2023 Zhenyi Wang, Li Shen, Donglin Zhan, Qiuling Suo, Yanjun Zhu, Tiehang Duan, Mingchen Gao

To make them trustworthy and robust to corruptions deployed in safety-critical scenarios, we propose a meta-learning framework of self-adaptive data augmentation to tackle the corruption robustness in CL.

Meta-Learning with Less Forgetting on Large-Scale Non-Stationary Task Distributions

1 code implementation3 Sep 2022 Zhenyi Wang, Li Shen, Le Fang, Qiuling Suo, Donglin Zhan, Tiehang Duan, Mingchen Gao

Two key challenges arise in this more realistic setting: (i) how to use unlabeled data in the presence of a large amount of unlabeled out-of-distribution (OOD) data; and (ii) how to prevent catastrophic forgetting on previously learned task distributions due to the task distribution shift.

Improving Task-free Continual Learning by Distributionally Robust Memory Evolution

1 code implementation15 Jul 2022 Zhenyi Wang, Li Shen, Le Fang, Qiuling Suo, Tiehang Duan, Mingchen Gao

To address these problems, for the first time, we propose a principled memory evolution framework to dynamically evolve the memory data distribution by making the memory buffer gradually harder to be memorized with distributionally robust optimization (DRO).

Learning To Learn and Remember Super Long Multi-Domain Task Sequence

1 code implementation CVPR 2022 Zhenyi Wang, Li Shen, Tiehang Duan, Donglin Zhan, Le Fang, Mingchen Gao

We propose a domain shift detection technique to capture latent domain change and equip the meta optimizer with it to work in this setting.

Uncertainty Detection and Reduction in Neural Decoding of EEG Signals

1 code implementation28 Dec 2021 Tiehang Duan, Zhenyi Wang, Sheng Liu, Sargur N. Srihari, Hui Yang

In this work, we proposed an uncertainty estimation and reduction model (UNCER) to quantify and mitigate the uncertainty during the EEG decoding process.

Meta Learning on a Sequence of Imbalanced Domains with Difficulty Awareness

1 code implementation ICCV 2021 Zhenyi Wang, Tiehang Duan, Le Fang, Qiuling Suo, Mingchen Gao

In this paper, we explore a more practical and challenging setting where task distribution changes over time with domain shift.

Towards Learning to Remember in Meta Learning of Sequential Domains

no code implementations1 Jan 2021 Zhenyi Wang, Tiehang Duan, Donglin Zhan, Changyou Chen

However, a natural generalization to the sequential domain setting to avoid catastrophe forgetting has not been well investigated.

Attention based Writer Independent Handwriting Verification

1 code implementation7 Sep 2020 Mohammad Abuzar Shaikh, Tiehang Duan, Mihir Chauhan, Sargur Srihari

The task of writer verification is to provide a likelihood score for whether the queried and known handwritten image samples belong to the same writer or not.

Ultra Efficient Transfer Learning with Meta Update for Cross Subject EEG Classification

2 code implementations13 Mar 2020 Tiehang Duan, Mihir Chauhan, Mohammad Abuzar Shaikh, Jun Chu, Sargur Srihari

The pattern of Electroencephalogram (EEG) signal differs significantly across different subjects, and poses challenge for EEG classifiers in terms of 1) effectively adapting a learned classifier onto a new subject, 2) retaining knowledge of known subjects after the adaptation.

Parallel Clustering of Single Cell Transcriptomic Data with Split-Merge Sampling on Dirichlet Process Mixtures

1 code implementation25 Dec 2018 Tiehang Duan, José P. Pinto, Xiaohui Xie

Motivation: With the development of droplet based systems, massive single cell transcriptome data has become available, which enables analysis of cellular and molecular processes at single cell resolution and is instrumental to understanding many biological processes.
