New Artificial Intelligence Research Suggests ExaRanker: Exploring the Role of Natural Language Explanations in Improving Information Retrieval Models
Information retrieval (IR) problems have seen significant improvements in trained transformers such as BERT and T5, refined on millions of instances. The model is expected to perform better than unsupervised models when the queries and documents from the task of interest are comparable to those in the fine-tuning data. For example, in 15 out of …
