Self-organized critical dynamics of RNA virus evolution

no code implementations19 Apr 2022 Xiaofei Ge, Kaichao You, Zeren Tan, Hedong Hou, Yang Tian, Pei Sun

We anticipate our approach to be a general formalism to portray RNA virus evolution and help identify potential virus lineages to be concerned.

From Big to Small: Adaptive Learning to Partial-Set Domains

1 code implementation14 Mar 2022 Zhangjie Cao, Kaichao You, Ziyang Zhang, Jianmin Wang, Mingsheng Long

Still, the common requirement of identical class space shared across domains hinders applications of domain adaptation to partial-set domains.

Ranking and Tuning Pre-trained Models: A New Paradigm for Exploiting Model Hubs

1 code implementation20 Oct 2021 Kaichao You, Yong liu, Ziyang Zhang, Jianmin Wang, Michael I. Jordan, Mingsheng Long

(2) The best ranked PTM can either be fine-tuned and deployed if we have no preference for the model's architecture or the target PTM can be tuned by the top $K$ ranked PTMs via a Bayesian procedure that we propose.

LogME: Practical Assessment of Pre-trained Models for Transfer Learning

1 code implementation22 Feb 2021 Kaichao You, Yong liu, Jianmin Wang, Mingsheng Long

In pursuit of a practical assessment method, we propose to estimate the maximum value of label evidence given features extracted by pre-trained models.

Stochastic Normalization

2 code implementations NeurIPS 2020 Zhi Kou, Kaichao You, Mingsheng Long, Jianmin Wang

During training, two branches are stochastically selected to avoid over-depending on some sample statistics, resulting in a strong regularization effect, which we interpret as ``architecture regularization.''

Co-Tuning for Transfer Learning

2 code implementations NeurIPS 2020 Kaichao You, Zhi Kou, Mingsheng Long, Jianmin Wang

Fine-tuning pre-trained deep neural networks (DNNs) to a target dataset, also known as transfer learning, is widely used in computer vision and NLP.

How Does Learning Rate Decay Help Modern Neural Networks?

no code implementations ICLR 2020 Kaichao You, Mingsheng Long, Jian-Min Wang, Michael. I. Jordan

Despite the popularity of these common beliefs, experiments suggest that they are insufficient in explaining the general effectiveness of lrDecay in training modern neural networks that are deep, wide, and nonconvex.

Towards Accurate Model Selection in Deep Unsupervised Domain Adaptation

2 code implementations International Conference on Machine Learning 2019 Kaichao You, Ximei Wang, Mingsheng Long, Michael Jordan

Deep unsupervised domain adaptation (Deep UDA) methods successfully leverage rich labeled data in a source domain to boost the performance on related but unlabeled data in a target domain.

Learning to Transfer Examples for Partial Domain Adaptation

1 code implementation CVPR 2019 Zhangjie Cao, Kaichao You, Mingsheng Long, Jian-Min Wang, Qiang Yang

Under the condition that target labels are unknown, the key challenge of PDA is how to transfer relevant examples in the shared classes to promote positive transfer, and ignore irrelevant ones in the specific classes to mitigate negative transfer.
