SDR: Efficient Neural Re-ranking using Succinct Document Representation

Nachshon Cohen, Amit Portnoy, Besnik Fetahu, Amir Ingber

ACL 2022long

BERT based ranking models have achieved superior performance on various information retrieval tasks. However, the large number of parameters and complex self-attention operations come at a significant latency overhead. To remedy this, recent works propose late-interaction architectures, which allow…

A Diagonal-Augmented quasi-Newton method with application to factorization machines

Aryan Mokhtari, Amir Ingber

ICASSP 2017accepted

We present a novel quasi-Newton method for convex optimization, in which the Hessian estimates are based not only on the gradients, but also on the diagonal part of the true Hessian matrix (which can often be obtained with reasonable complexity). The new algorithm is based on the well known Broyden-…
