Comparing LLMs and Traditional Machine Translation for Medical Consultation Summaries

A. Li, W. Zhou, R. Hoda, C. Bain & P. Poon

A first-authored pilot study comparing three LLMs (GPT-4o, Llama-3.1, Gemma-2) against three traditional machine-translation tools for translating English medical summaries into Arabic, Chinese, and Vietnamese. Traditional MT led on surface metrics, while LLMs showed relative strengths in semantic similarity — underscoring the need for human review before clinical use.

Cooperative-ORCA*: Proactive Deadlock Avoidance for Continuous-Space MAPF

Student research project · supervised by A. Li

C-ORCA* and C-ORCA*-MAPF are continuous-space multi-agent path-finding algorithms that prevent deadlocks by reasoning over agents' full trajectories, removing the post-hoc correction overhead of prior real-time solvers. They cut expensive MAPF fallbacks by 3–4 orders of magnitude and sustain a ~100% success rate at 200 agents — at near-zero per-timestep overhead.

Large Language Models for Summarizing Palliative Care Consultations

X. Chen, W. Zhou, R. Hoda, A. Li, C. Bain & P. Poon

A peer-reviewed pilot evaluating GPT-3.5, GPT-4, and LLaMA 2 for zero-shot summarisation of doctor–patient palliative-care consultations. Summary quality was benchmarked with BLEU, ROUGE-L, METEOR, and BERTScore alongside readability scoring — GPT-4 led on most metrics, while LLaMA 70B produced the simplest, most readable summaries for patients.
