Streszczenie
The content describes the development of a dialogue system that aims to help heart failure patients, particularly African Americans, monitor and reduce their salt intake. The key highlights are:
Heart failure patients, especially African Americans, face significant health risks due to excessive salt consumption, but lack knowledge and tools to manage their salt intake effectively.
To address this, the authors propose a dialogue system that enables users to inquire about the salt content in different foods and provides accurate information.
The authors create a template-based conversational dataset to train the dialogue system, leveraging the USFDC (U.S. Food Data Central) dataset and developing a food ontology to identify various food attributes.
The authors fine-tune the PPTOD (Plug-and-Play Task-Oriented Dialogue System) model on the dataset using a few-shot approach.
To enhance the system's performance in accurately determining salt values, the authors integrate neuro-symbolic rules with the PPTOD model, creating the NS-PPTOD system.
Experiments show that the integration of neuro-symbolic rules significantly improves the system's performance, with a 20% increase in joint accuracy compared to the fine-tuned PPTOD model.
The authors also compare the readability of the responses from NS-PPTOD and ChatGPT, demonstrating that NS-PPTOD's responses are more accessible to the target audience of heart failure patients.
Statystyki
Excessive sodium intake was associated with around three million deaths and a significant loss of healthy life years in 2017.
Only 58% of individuals can accurately read sodium content on nutrition labels, and merely 44% can classify food products as high or low in sodium based on standard labeling.
Cytaty
"Reducing salt intake has been shown to mitigate these health issues."
"African American individuals who are more prone to heart failure (Nayak et al., 2020), have a higher sensitivity to salt and face challenges like food deserts and higher consumption of junk foods."
