Retrieving and Refining Winning Noise Tickets for Diffusion-Based Motion Generation

Sakuya Ota, Qing Yu, Kent Fujiwara +2

Diffusion-based text-to-motion models synthesize realistic human motions but often exhibit semantic drift from the input text. Motion is inherently temporal, especially in composit…

What-Where Transformer: A Slot-Centric Visual Backbone for Concurrent Representation and Localization

Ryota Yoshihashi, Masahiro Kada, Satoshi Ikehata +2

Many image understanding tasks involve identifying what is present and where it appears. However, tasks that address where, such as object discovery, detection, and segmentation, a…

Rectified Lagrangian for Out-of-Distribution Detection in Modern Hopfield Networks

Ryo Moriai, Nakamasa Inoue, Masayuki Tanaka +3

Modern Hopfield networks (MHNs) have recently gained significant attention in the field of artificial intelligence because they can store and retrieve a large set of patterns with…
