LoDEOT: Low-Dimensional and Efficient Offset Tokens for Building Footprint Extraction from Off-Nadir Imagery

Kai Li, Zigan Zhou, Zhenyang Li وآخرون · 2026

Instance-level roof-to-footprint offset (RFO) prediction is central to extracting building footprints from off-nadir imagery. Query-based pipelines commonly use high-dimensional instance tokens to predict signed two-dimensional RFOs. We investigate whether RFO prediction can instead use a compact offset token. Under lo …

Sibyl: An Efficient Small-large Model Collaboration Framework for Long-horizon Tasks

Zhewei Fang, Yuxin Zhang, Zhenwei Shao وآخرون · 2026

Small language models (SLMs) offer a promising foundation for on-device agents through low-latency, resource-efficient inference, yet limited reasoning and planning capabilities constrain their performance on long-horizon tasks requiring multi-step interaction with the environment. Step-level collaboration between SLMs …

Redundancy Meets Synergy: Dependency-aware Expert Selection for MoE via Submodular Optimization

Zheng Lin, Shaoke Fang, Yuxin Zhang وآخرون · 2026

While Mixture-of-Experts (MoE) models effectively scale model capacity through sparse activation, their deployment is often bottlenecked by prohibitive memory requirements. Extracting a compact subset of experts presents a promising solution. However, existing expert selection heuristics predominantly rely on Top-k ran …
