Evaluation of Synthetic Datasets for Conversational Recommender Systems
This addresses a critical bottleneck for researchers using LLMs to generate training data, though it appears incremental as it focuses on evaluation rather than new data or methods.
The paper tackles the problem of lacking robust evaluation frameworks for synthetic datasets generated by LLMs in conversational recommender systems, presenting a multi-faceted framework to assess data quality and biases.
For researchers leveraging Large-Language Models (LLMs) in the generation of training datasets, especially for conversational recommender systems - the absence of robust evaluation frameworks has been a long-standing problem. The efficiency brought about by LLMs in the data generation phase is impeded during the process of evaluation of the generated data, since it generally requires human-raters to ensure that the data generated is of high quality and has sufficient diversity. Since the quality of training data is critical for downstream applications, it is important to develop metrics that evaluate the quality holistically and identify biases. In this paper, we present a framework that takes a multi-faceted approach towards evaluating datasets produced by generative models and discuss the advantages and limitations of various evaluation methods.
