PA-CoT: Profile-Adaptive Chain-of-Thought for Personalized Nutritional Consulting

Read the original on arXiv Machine Learning →

PA-CoT (Profile-Adaptive Chain-of-Thought) is a multi-stage prompting method that explicitly analyzes user profiles before generating responses for personalized nutritional consulting. The authors introduce the QPA benchmark, comprising 200 samples with structured profiles scored on four criteria, to evaluate personalization and safety. In a comparative study against 11 other methods, PA-CoT achieves the highest average score (4.21) and leads in both personalization (4.71) and safety (4.68) with statistically significant margins.

Investigating the Ability of Large Language Models to Analyze Recipes for Diabetes

The paper examines how large language models (LLMs) can assess whether recipes are suitable for people with diabetes. It introduces a benchmark of 7,607 recipes, split evenly between suitable and unsuitable, and tests three prompting strategies that embed varying levels of diabetes dietary guidelines. Results show that LLMs tend to be cautious in labeling recipes as suitable, and those that can reason with the guidelines—particularly Mistral‑7B and Llama‑70B—perform best.

Investigating the Ability of Large Language Models to Analyze Recipes for Diabetes

The paper investigates how well large language models (LLMs) can assess whether recipes are suitable for people with diabetes. It introduces a benchmark of 7,607 recipes, split evenly between suitable and unsuitable, and tests three prompting strategies that vary in how much diabetes dietary guidance they provide. Results show that LLMs tend to be cautious in labeling recipes as suitable, and those that can reason with dietary guidelines—particularly Mistral‑7B and Llama‑70B—perform best.
