Beyond Simple Motions: How SentiAvatar Redefines 3D Digital Human Action Generation

SentiAvatar introduces a two‑stage plan‑then‑infill framework that separates sentence‑level semantic planning from frame‑level prosody‑driven motion infill, leveraging a 200K‑sequence Motion Foundation Model and the newly released 21k‑clip SuSuInterActs dataset to achieve state‑of‑the‑art, real‑time expressive 3D digital human animation.

LPR4M: A Large-Scale Multimodal Livestreaming Product Recognition Dataset and the RICE Cross‑View Semantic Alignment Model

This paper introduces LPR4M, a 4‑million‑pair multimodal dataset for livestreaming product recognition, and proposes the RICE model that combines instance‑level contrastive learning with patch‑level cross‑view semantic alignment, demonstrating state‑of‑the‑art performance on both LPR4M and MovingFashion benchmarks.
