Visit My WorksCan we improve search result clustering (SRC) by directly involving the query context into the trained similarity metric used for clustering? To investigate this, we propose Query-Specific Siamese Similarity Metric (QS3M) for query-specific clustering of text documents
Read moreCan we generalize contrastive learning for clustering tasks by directly optimizing for a clustering quality metric like RAND index? We present Clustering Optimization as Blackbox (COB) that employs a recent optimization technique suitable for discrete metrics and show that it leads to better representations suitable for clustering.
Read moreDense Passage Retrieval (DPR) relies on the underlying embedding space to find relevant documents in response to a query. In this work, we explore whether the embedding model trained with an auxiliary clustering objective improves the retrieval quality of a DPR system.
