Resources and Evaluations for Multi-Distribution Dense Information Retrieval

1 code implementation21 Jun 2023 Soumya Chatterjee, Omar Khattab, Simran Arora

We introduce and define the novel problem of multi-distribution information retrieval (IR) where given a query, systems need to retrieve passages from within multiple collections, each drawn from a different distribution.

Matching options to tasks using Option-Indexed Hierarchical Reinforcement Learning

no code implementations12 Jun 2022 Kushal Chauhan, Soumya Chatterjee, Akash Reddy, Balaraman Ravindran, Pradeep Shenoy

The options framework in Hierarchical Reinforcement Learning breaks down overall goals into a combination of options or simpler tasks and associated policies, allowing for abstraction in the action space.

Joint Learning of Hyperbolic Label Embeddings for Hierarchical Multi-label Classification

1 code implementation EACL 2021 Soumya Chatterjee, Ayush Maheshwari, Ganesh Ramakrishnan, Saketha Nath Jagaralpudi

Such a joint learning is expected to provide a twofold advantage: i) the classifier generalizes better as it leverages the prior knowledge of existence of a hierarchy over the labels, and ii) in addition to the label co-occurrence information, the label-embedding may benefit from the manifold structure of the input datapoints, leading to embeddings that are more faithful to the label hierarchy.
