Sanitized Clustering against Confounding Bias

1 code implementation2 Nov 2023 Yinghua Yao, Yuangang Pan, Jing Li, Ivor W. Tsang, Xin Yao

Therein, the interested clustering factor and the confounding factor are coarsely considered in the raw feature space, where the correlation between the data and the confounding factor is ideally assumed to be linear for convenient solutions.

Earning Extra Performance from Restrictive Feedbacks

1 code implementation28 Apr 2023 Jing Li, Yuangang Pan, Yueming Lyu, Yinghua Yao, Yulei Sui, Ivor W. Tsang

Unlike existing model tuning methods where the target data is always ready for calculating model gradients, the model providers in EXPECTED only see some feedbacks which could be as simple as scalars, such as inference accuracy or usage rate.

Coarse-to-Fine Contrastive Learning on Graphs

no code implementations13 Dec 2022 Peiyao Zhao, Yuangang Pan, Xin Li, Xu Chen, Ivor W. Tsang, Lejian Liao

Inspired by the impressive success of contrastive learning (CL), a variety of graph augmentation strategies have been employed to learn node representations in a self-supervised manner.

Taming Overconfident Prediction on Unlabeled Data from Hindsight

no code implementations15 Dec 2021 Jing Li, Yuangang Pan, Ivor W. Tsang

The prediction uncertainty is typically expressed as the \emph{entropy} computed by the transformed probabilities in output space.

TRIP: Refining Image-to-Image Translation via Rival Preferences

no code implementations26 Nov 2021 Yinghua Yao, Yuangang Pan, Ivor W. Tsang, Xin Yao

In particular, we simultaneously train two modules: a generator that translates an input image to the desired image with smooth subtle changes with respect to the interested attributes; and a ranker that ranks rival preferences consisting of the input image and the desired image.

Fine-Tuning from Limited Feedbacks

no code implementations29 Sep 2021 Jing Li, Yuangang Pan, Yueming Lyu, Yinghua Yao, Ivor Tsang

Instead of learning from scratch, fine-tuning a pre-trained model to fit a related target dataset of interest or downstream tasks has been a handy trick to achieve the desired performance.

Differential-Critic GAN: Generating What You Want by a Cue of Preferences

1 code implementation14 Jul 2021 Yinghua Yao, Yuangang Pan, Ivor W. Tsang, Xin Yao

This paper proposes Differential-Critic Generative Adversarial Network (DiCGAN) to learn the distribution of user-desired data when only partial instead of the entire dataset possesses the desired property.

Streamlining EM into Auto-Encoder Networks

no code implementations1 Jan 2021 Yuangang Pan, Ivor Tsang

We present a new deep neural network architecture, named EDGaM, for deep clustering.

Multi-view Alignment and Generation in CCA via Consistent Latent Encoding

no code implementations24 May 2020 Yaxin Shi, Yuangang Pan, Donna Xu, Ivor W. Tsang

Multi-view alignment, achieving one-to-one correspondence of multi-view inputs, is critical in many real-world multi-view applications, especially for cross-view data analysis problems.

Secure Metric Learning via Differential Pairwise Privacy

no code implementations30 Mar 2020 Jing Li, Yuangang Pan, Yulei Sui, Ivor W. Tsang

This paper studies, for the first time, how pairwise information can be leaked to attackers during distance metric learning, and develops differential pairwise privacy (DPP), generalizing the definition of standard differential privacy, for secure metric learning.

Probabilistic CCA with Implicit Distributions

no code implementations4 Jul 2019 Yaxin Shi, Yuangang Pan, Donna Xu, Ivor Tsang

Although some works have studied probabilistic interpretation for CCA, these models still require the explicit form of the distributions to achieve a tractable solution for the inference.

Fast and Robust Rank Aggregation against Model Misspecification

1 code implementation29 May 2019 Yuangang Pan, WeiJie Chen, Gang Niu, Ivor W. Tsang, Masashi Sugiyama

Specifically, the properties of our CoarsenRank are summarized as follows: (1) CoarsenRank is designed for mild model misspecification, which assumes there exist the ideal preferences (consistent with model assumption) that locates in a neighborhood of the actual preferences.

Mental Fatigue Monitoring using Brain Dynamics Preferences

no code implementations ICLR 2019 Yuangang Pan, Avinash K Singh, Ivor W. Tsang, Chin-Teng Lin

Furthermore, a transition matrix is introduced to characterize the reliability of each channel used in EEG data, which helps in learning brain dynamics preferences only from informative EEG channels.

Canonical Correlation Analysis with Implicit Distributions

no code implementations27 Sep 2018 Yaxin Shi, Donna Xu, Yuangang Pan, Ivor Tsang

Based on this objective, we present an implicit probabilistic formulation for CCA, named Implicit CCA (ICCA), which provides a flexible framework to design CCA extensions with implicit distributions.
