Mixed-Modality Dual Face-Hair Retrieval
Quoc-Anh Bui-Huynh, Mai-Tuyen Lam, Dai-Anh-Tuan Nguyen +1
We introduce Dual Face-Hair Retrieval (DFHR), a new mixed-modality dual-reference task in image retrieval where a query consists of a face image specifying identity and a hairstyle…
Multiple Wasserstein Gradient Descent Algorithm for Multi-Objective Distributional Optimization
Dai Hai Nguyen, Hiroshi Mamitsuka, Atsuyoshi Nakamura
We address the optimization problem of simultaneously minimizing multiple objective functionals over a family of probability distributions. This type of Multi-Objective Distributio…
Wasserstein Gradient Flow over Variational Parameter Space for Variational Inference
Dai Hai Nguyen, Tetsuya Sakurai, Hiroshi Mamitsuka
Variational inference (VI) can be cast as an optimization problem in which the variational parameters are tuned to closely align a variational distribution with the true posterior.…
A Particle-Based Algorithm for Distributional Optimization on \textit{Constrained Domains} via Variational Transport and Mirror Descent
Dai Hai Nguyen, Tetsuya Sakurai
We consider the optimization problem of minimizing an objective functional, which admits a variational form and is defined over probability distributions on the constrained domain,…
