Towards Efficient Pareto-optimal Utility-Fairness between Groups in Repeated Rankings

no code implementations22 Feb 2024 Phuong Dinh Mai, Duc-Trong Le, Tuan-Anh Hoang, Dung D. Le

On the Expohedron, we profile the Pareto curve which captures the trade-off between group fairness and user utility by identifying a finite number of Pareto optimal solutions.

Controllable Expensive Multi-objective Learning with Warm-starting Bayesian Optimization

no code implementations26 Nov 2023 Quang-Huy Nguyen, Long P. Hoang, Hoang V. Viet, Dung D. Le

Pareto Set Learning (PSL) is a promising approach for approximating the entire Pareto front in multi-objective optimization (MOO) problems.

Improving Pareto Front Learning via Multi-Sample Hypernetworks

1 code implementation2 Dec 2022 Long P. Hoang, Dung D. Le, Tran Anh Tuan, Tran Ngoc Thang

Pareto Front Learning (PFL) was recently introduced as an effective approach to obtain a mapping function from a given trade-off vector to a solution on the Pareto front, which solves the multi-objective optimization (MOO) problem.

Enhancing Few-shot Image Classification with Cosine Transformer

1 code implementation13 Nov 2022 Quang-Huy Nguyen, Cuong Q. Nguyen, Dung D. Le, Hieu H. Pham

This might result in a significant difference between support and query samples, therefore undermining the performance of few-shot algorithms.

Improving Transformers with Probabilistic Attention Keys

1 code implementation16 Oct 2021 Tam Nguyen, Tan M. Nguyen, Dung D. Le, Duy Khuong Nguyen, Viet-Anh Tran, Richard G. Baraniuk, Nhat Ho, Stanley J. Osher

Inspired by this observation, we propose Transformer with a Mixture of Gaussian Keys (Transformer-MGK), a novel transformer architecture that replaces redundant heads in transformers with a mixture of keys at each head.
