Abstrakt: The article focuses on addressing the inefficiency of dual-encoder-based dense retrieval models in information retrieval (IR) by proposing Fast-Forward indexes, which leverage semantic matching capabilities for efficient re-ranking. By enhancing computational efficiency and optimizing memory footprint, Fast-Forward indexes achieve low latency and competitive results in IR tasks without requiring hardware acceleration like GPUs.
