Predictive Uncertainty-based Bias Mitigation in Ranking

Maria Heuss, Daniel Cohen, Masoud Mansoury +2

Societal biases that are contained in retrieved documents have received increased interest. Such biases, which are often prevalent in the training data and learned by the model, ca…

A Lightweight Constrained Generation Alternative for Query-focused Summarization

Zhichao Xu, Daniel Cohen

Query-focused summarization (QFS) aims to provide a summary of a document that satisfies information need of a given query and is useful in various IR applications, such as abstrac…

Parameter-efficient Modularised Bias Mitigation via AdapterFusion

Deepak Kumar, Oleg Lesota, George Zerveas +4

Large pre-trained language models contain societal biases and carry along these biases to downstream tasks. Current in-processing bias mitigation approaches (like adversarial train…

Metric-valued regression

Dan Tsir Cohen, Aryeh Kontorovich

We propose an efficient algorithm for learning mappings between two metric spaces, $\X$ and $\Y$. Our procedure is strongly Bayes-consistent whenever $\X$ and $\Y$ are topologicall…

A Modern Perspective on Query Likelihood with Deep Generative Retrieval Models

Oleg Lesota, Navid Rekabsaz, Daniel Cohen +3

Existing neural ranking models follow the text matching paradigm, where document-to-query relevance is estimated through predicting the matching score. Drawing from the rich litera…

Not All Relevance Scores are Equal: Efficient Uncertainty and Calibration Modeling for Deep Retrieval Models

Daniel Cohen, Bhaskar Mitra, Oleg Lesota +2

In any ranking system, the retrieval model outputs a single score for a document based on its belief on how relevant it is to a given search query. While retrieval models have cont…
