Tabular Data Contrastive Learning via Class-Conditioned and Feature-Correlation Based Augmentation

2 code implementations26 Apr 2024 Wei Cui, Rasa Hosseinzadeh, Junwei Ma, Tongzi Wu, Yi Sui, Keyvan Golestan

Contrastive learning is a model pre-training technique by first creating similar views of the original data, and then encouraging the data and its corresponding views to be close in the embedding space.

Conformal Prediction Sets Improve Human Decision Making

1 code implementation24 Jan 2024 Jesse C. Cresswell, Yi Sui, Bhargava Kumar, Noël Vouitsis

In response to everyday queries, humans explicitly signal uncertainty and offer alternative answers when they are unsure.

Equirectangular image construction method for standard CNNs for Semantic Segmentation

no code implementations13 Oct 2023 Haoqian Chen, Jian Liu, Minghe Li, Kaiwen Jiang, Ziheng Xu, Rencheng Sun, Yi Sui

In addition, there are few publicly dataset of equirectangular images with labels, which presents a challenge for standard CNNs models to process equirectangular images effectively.

Self-supervised Representation Learning From Random Data Projectors

1 code implementation11 Oct 2023 Yi Sui, Tongzi Wu, Jesse C. Cresswell, Ga Wu, George Stein, Xiao Shi Huang, Xiaochen Zhang, Maksims Volkovs

Self-supervised representation learning~(SSRL) has advanced considerably by exploiting the transformation invariance assumption under artificially designed data augmentations.

Exposing flaws of generative model evaluation metrics and their unfair treatment of diffusion models

2 code implementations NeurIPS 2023 George Stein, Jesse C. Cresswell, Rasa Hosseinzadeh, Yi Sui, Brendan Leigh Ross, Valentin Villecroze, Zhaoyan Liu, Anthony L. Caterini, J. Eric T. Taylor, Gabriel Loaiza-Ganem

Comparing to 17 modern metrics for evaluating the overall performance, fidelity, diversity, rarity, and memorization of generative models, we find that the state-of-the-art perceptual realism of diffusion models as judged by humans is not reflected in commonly reported metrics such as FID.

Find Your Friends: Personalized Federated Learning with the Right Collaborators

no code implementations12 Oct 2022 Yi Sui, Junfeng Wen, Yenson Lau, Brendan Leigh Ross, Jesse C. Cresswell

In the traditional federated learning setting, a central server coordinates a network of clients to train one global model.

Multi-axis Attentive Prediction for Sparse EventData: An Application to Crime Prediction

1 code implementation5 Oct 2021 Yi Sui, Ga Wu, Scott Sanner

We additionally introduce a novel Frobenius norm-based contrastive learning objective to improve latent representational generalization. Empirically, we validate MAPSED on two publicly accessible urban crime datasets for spatiotemporal sparse event prediction, where MAPSED outperforms both classical and state-of-the-art deep learning models.
