Towards Safer Social Media Platforms: Scalable and Performant Few-Shot Harmful Content Moderation Using Large Language Models

The paper presents a scalable approach to harmful content moderation on social media by leveraging large language models (LLMs) for few-shot, in-context learning. Experiments across multiple LLMs show that this method outperforms proprietary baselines such as Perspective and OpenAI Moderation, as well as prior few-shot learning techniques, in detecting harmful content. The study also explores the addition of visual cues like video thumbnails to assess multimodal improvements, highlighting the advantages of LLM-based moderation for dynamic and large-scale content filtering.

FlowExtract: Procedural Knowledge Extraction from Maintenance Flowcharts

FlowExtract is a pipeline designed to convert ISO 5807-standardized maintenance flowcharts into directed graphs. It separates node detection—using YOLOv8 and EasyOCR—from connectivity reconstruction, employing a novel edge detection method that traces arrowheads back to source nodes. Evaluations on industrial troubleshooting guides show high node detection accuracy and significant improvement over vision‑language model baselines for edge extraction.

UR$^{2}$-MLLM: Uncertainty-aware Revisit Reasoning in Multimodal Large Language Models for Radiology Report Generation

The paper introduces UR$^{2}$-MLLM, an uncertainty‑aware multimodal large language model that dynamically revisits uncertain image regions during radiology report generation. It incorporates an uncertainty perception module trained on a specialized dataset, builds a multimodal reasoning trajectory with a detect‑and‑copy mechanism to guide revisits, and refines this behavior using a visual grounding reward via reinforcement learning. Experiments on MIMIC‑CXR and IU‑Xray demonstrate state‑of‑the‑art performance, underscoring the importance of visual revisit reasoning for reliable, clinically aligned reports.

Mol-JEPA: A multimodal Joint Embedding Predictive Architecture for Molecules

Mol-JEPA is a scalable multimodal framework that learns molecular world models by using modality masking instead of suboptimal perturbations. It incorporates diverse data such as molecular structures, cellular phenotypes, binding affinities, ADMET profiles, quantum chemistry simulations, and other drug‑discovery information. Benchmarks show that the representations it learns perform strongly, highlighting the benefit of embedding biochemical context via latent‑space prediction.

LanGuSTE: Language-Guided Coarse-to-Fine Patch Selection for Efficient Whole Slide Image Analysis

LanGuSTE is a patch‑selection framework for whole slide image analysis that uses vision‑language models and large language model knowledge. It introduces Cross‑Scale Visual Prompt Tuning to align low‑resolution and high‑resolution patches, and a coarse‑to‑fine selection module that encodes only informative high‑resolution patches. Experiments show LanGuSTE cuts overall processing time to about one‑third of the baseline while matching or surpassing diagnostic performance of exhaustive and state‑of‑the‑art methods.
