SIF3D: Sense‑Informed Forecasting of 3D Human Motion with Multimodal Attention

SIF3D is a scene‑aware 3D human motion forecasting framework that fuses observed motion, 3D point‑cloud scenes, and gaze through novel ternary intention‑aware and semantic‑coherence‑aware attention mechanisms, encoding with PointNet++ and Transformers, and decoding with a graph‑convolutional network, achieving state‑of‑the‑art results on GIMO and GTA‑1M benchmarks.

Generative Dense Retrieval: Memory Can Be a Burden

The paper introduces Generative Dense Retrieval (GDR), a two‑stage retrieval framework that first maps queries to memory‑efficient document‑cluster identifiers and then uses dense vectors to locate individual documents, achieving higher recall and better scalability than traditional generative retrieval while incurring modest latency and capacity trade‑offs.

Early‑Stopping Self‑Consistency (ESC): Reducing Sampling Cost for Large Language Model Reasoning

Early‑Stopping Self‑Consistency (ESC) dynamically halts sampling once a sliding‑window answer distribution reaches zero entropy, cutting the number of required LLM reasoning samples by 34‑84 % across arithmetic, commonsense, and symbolic benchmarks while preserving accuracy and offering a theoretically‑bounded, robust, budget‑adaptive alternative to traditional Self‑Consistency.

Encoding‑Alignment‑Interaction (EAI) Framework for Full‑Body Human Motion Forecasting

The Encoding‑Alignment‑Interaction (EAI) framework predicts full‑body human motion—including detailed hand joints—by extracting spatio‑temporal features with DCT and GCNs, aligning heterogeneous body‑hand representations via Cross‑Context Alignment, and modeling semantic and physical interactions through Cross‑Context Interaction, achieving state‑of‑the‑art accuracy on the GRAB dataset.
