AI safety isn’t universal. #UbuntuGuard, led by researchers at @brownpublichealth.bsky.social and collaborators, shows that models that pass English benchmarks can fail when tested against locally grounded policy rules across African languages. Read more: rebootdemocracy.ai/blog/ubuntu-...

Evaluating AI Safety Through Local Policy: Findings from the UbuntuGuard benchmark

A new paper introducing the UbuntuGuard benchmark questions whether strong results on English-language safety tests consistently translate into responsible use. Built from policies developed by 155 Af...

6/n: We release: - The dataset for KG-based inductive reasoning: huggingface.co/Tassy24 - Paper: arxiv.org/abs/2502.13344 - Repo: github.com/rsinghlab/K-Pa…. Big thanks to all my incredible collaborators- this wouldn’t be possible without your brilliance!

5/n: This open doors in biomedical AI: • Structured KG reasoning + LLMs' generative power = transparent, scientific discovery. • Imagine helping scientists understand why a treatment works, not just what!

4/n: Why this matters: • Interpretability baked in - paths double as explanations. •Efficiency - huge KG reductions help scale to real-world biomedical workloads. •Generalization - works in unseen (inductive) settings.

3/n: 🔥 Results across model families (LLMs & GNNs): • Tx-Gemma 27B: +19.8 F1 on interaction severity • Llama 70B: +8.5 F1 on similar tasks. • EmerGNN: trains on 90% smaller KG with no loss in accuracy • That cross-architecture gain is rarely seen and hard to ignore.

2/n: K-Paths is not just a retrieval method. It’s a pipeline that combines: • Heuristics path finding (Yen’s algorithm) • Diversity-aware selection • Graph pruning • Natural language transformation to aid reasoning for LLMs. •GNN/LLM integration

1/n: Most KG methods for drug discovery tasks rely on GNNs or focus on narrow QA tasks. K-Paths is model-agnostic and reframes KG use for reasoning & discovery, especially in inductive settings (e.g. emerging drugs/diseases).

Thrilled to share our KDD 2025 paper: Can large language models (LLMs) reason like biomedical scientists? We introduce K-Paths, a retrieval framework for extracting reasoning paths from knowledge graphs (KGs) to aid drug discovery tasks. 👇 Thread:

Speech tech is everywhere, even healthcare. But how well does it work for African accented English? 🤔 We benchmarked SOTA models for speaker diarization, ASR & LLM summarization on medical & general conversations. Find me at the 11 am poster session in Hall 3 to learn more! #NLP4Healthcare
