Exploring Recurrent-Depth Language Models for Multitask Clinical Text Processing

The study evaluates small recurrent‑depth language models for multitask clinical text processing, fine‑tuning five models on nine datasets and testing on four unseen datasets. Across 13 tasks, Ouro‑1.4B‑Thinking outperformed Qwen3‑1.7B on 11 datasets, while Ouro‑2.6B‑Thinking matched Qwen3‑8B on most tasks, with the largest gains seen in inference and question answering. The results suggest recurrent‑depth architectures merit further controlled investigation for clinical NLP.

How Fine-Tuning Objectives Shape Layer-Wise Information in LLM Hallucination Detection

The study compares two fine‑tuning paradigms for detecting hallucinations in large language models: a classifier‑head (“cls”) and a sequence‑to‑sequence (“s2s”) approach. “Cls” consistently outperforms “s2s” because it induces a clear two‑cluster geometry in hidden states, enabling stronger class separation and linear decodability. Analysis of training dynamics reveals a narrow upper‑middle “InfoWindow” where task information emerges; truncating layers above this window removes 31% of the network without loss of accuracy and reduces latency by 1.4×, a strategy that transfers across multiple models and tasks.

Gibson Env: Real-World Perception for Embodied Agents

The paper introduces Gibson, a virtual environment designed to develop real‑world perception for active agents. Gibson virtualizes real spaces, containing over 1,400 floor plans from 572 buildings, and includes a synthesis mechanism called "Goggles" that allows models trained in simulation to be deployed directly in the real world without additional domain adaptation. The environment also embeds agents within realistic physics and spatial constraints to support embodied learning.

Dynamic Cross-Modal Prompt Generation for Multimodal Continual Instruction Tuning

Dynamic Cross-Modal Prompt Generation (DRAPE) is a prompt-learning framework designed for Multimodal Continual Instruction Tuning (MCIT). It generates continuous, instance-specific soft prompts by cross-attending textual instructions with visual patch features, rather than selecting from a fixed prompt pool. DRAPE also incorporates null‑space gradient projection to reduce forgetting and uses CLIP‑based prototype routing for task‑label‑free inference, achieving state‑of‑the‑art results on MCIT benchmarks.
