A Modular Multitask Reasoning Framework Integrating Spatio-temporal Models and LLMs

Read the original on arXiv AI →

The paper introduces STReason, a modular multitask reasoning framework that combines large language models with spatio‑temporal models to handle complex natural language queries without task‑specific fine‑tuning. STReason decomposes queries into interpretable programs, executes them to produce numerical results and detailed, computation‑grounded explanations, thereby reducing hallucinations. The authors evaluate the system on a new benchmark and show it outperforms advanced LLM baselines, with human studies confirming its credibility and practical utility.

STRAND: Benchmarking and Improving Object-Centric Spatio-Temporal Monitoring in Video Large Language Models

STRAND is a new benchmark that tests multimodal large language models’ ability to track objects, their states, and relationships over time in videos. It evaluates intermediate reasoning by breaking queries into sub‑questions and uses Faithful Accuracy to ensure all parts of an answer are correct. The authors also propose an object‑centric framework that builds structured trajectories and shows reduced hallucinations and better temporal consistency compared to existing models.

Generative Spatiotemporal Intent Sequence Recommendation via Implicit Reasoning in Amap

The paper introduces GPlan, a generative framework for Generative Spatiotemporal Intent Sequence Recommendation (GSISR) that integrates large language model reasoning into lightweight models. It employs Progressive Implicit CoT Distillation to compress reasoning into latent tokens for low-latency inference, and Spatiotemporal Counterfactual DPO to align plans with real-world constraints, improving sequence coherence and context responsiveness. Experiments and online A/B tests confirm the effectiveness of these techniques, and the authors provide an implementation and dataset on GitHub.
