Few-shot Prompting for Pairwise Ranking: An Effective Non-Parametric Retrieval Model

EMNLP 2024finding

A supervised ranking model, despite its effectiveness over traditional approaches, usually involves complex processing - typically multiple stages of task-specific pre-training and fine-tuning. This has motivated researchers to explore simpler pipelines leveraging large language models (LLMs) that c…

Neural Language Model Based Attentive Term Dependence Model for Verbose Query (Student Abstract)

AAAI 2023technical

The query-document term matching plays an important role in information retrieval. However, the retrieval performance degrades when the documents get matched with the extraneous terms of the query which frequently arises in verbose queries. To address this problem, we generate the dense vector of th…

A Study on the Ramanujan Graph Property of Winning Lottery Tickets

ICML 2022spotlight

Winning lottery tickets refer to sparse subgraphs of deep neural networks which have classification accuracy close to the original dense networks. Resilient connectivity properties of such sparse networks play an important role in their performance. The attempt is to identify a sparse and yet well-c…

Alternating Direction Method of Multipliers for Quantization

AISTATS 2021poster

Quantization of the parameters of machine learning models, such as deep neural networks, requires solving constrained optimization problems, where the constraint set is formed by the Cartesian product of many simple discrete sets. For such optimization problems, we study the performance of the Alter…

Prior Guided GAN Based Semantic Inpainting

CVPR 2020poster

Contemporary deep learning based semantic inpainting can be approached from two directions. First, and the more explored, approach is to train an offline deep regression network over the masked pixels with an additional refinement by adversarial training. This approach requires a single feed-forward…
