On the Problem of Underranking in Group-Fair Ranking

2 code implementations24 Sep 2020 Sruthi Gorantla, Amit Deshpande, Anand Louis

We give a fair ranking algorithm that takes any given ranking and outputs another ranking with simultaneous underranking and group fairness guarantees comparable to the lower bound we prove.

Sampling Ex-Post Group-Fair Rankings

2 code implementations2 Mar 2022 Sruthi Gorantla, Amit Deshpande, Anand Louis

Our second random walk-based algorithm samples ex-post group-fair rankings from a distribution $\delta$-close to $D$ in total variation distance and has expected running time $O^*(k^2\ell^2)$, when there is a sufficient gap between the given upper and lower bounds on the group-wise representation.

Optimizing Group-Fair Plackett-Luce Ranking Models for Relevance and Ex-Post Fairness

1 code implementation25 Aug 2023 Sruthi Gorantla, Eshaan Bhansali, Amit Deshpande, Anand Louis

Previous works have proposed efficient algorithms to train stochastic ranking models that achieve fairness of exposure to the groups ex-ante (or, in expectation), which may not guarantee representation fairness to the groups ex-post, that is, after realizing a ranking from the stochastic ranking model.

Aspect-Sentiment Embeddings for Company Profiling and Employee Opinion Mining

no code implementations22 Feb 2019 Rajiv Bajpai, Devamanyu Hazarika, Kunal Singh, Sruthi Gorantla, Erik Cambria, Roger Zimmerman

With the multitude of companies and organizations abound today, ranking them and choosing one out of the many is a difficult and cumbersome task.

Biologically Plausible Neural Networks via Evolutionary Dynamics and Dopaminergic Plasticity

no code implementations NeurIPS Workshop Neuro_AI 2019 Sruthi Gorantla, Anand Louis, Christos H. Papadimitriou, Santosh Vempala, Naganand Yadati

Artificial neural networks (ANNs) lack in biological plausibility, chiefly because backpropagation requires a variant of plasticity (precise changes of the synaptic weights informed by neural events that occur downstream in the neural circuit) that is profoundly incompatible with the current understanding of the animal brain.

Socially Fair Center-based and Linear Subspace Clustering

no code implementations22 Aug 2022 Sruthi Gorantla, Kishen N. Gowda, Amit Deshpande, Anand Louis

Center-based clustering (e. g., $k$-means, $k$-medians) and clustering using linear subspaces are two most popular techniques to partition real-world data into smaller clusters.

Sampling Individually-Fair Rankings that are Always Group Fair

no code implementations21 Jun 2023 Sruthi Gorantla, Anay Mehrotra, Amit Deshpande, Anand Louis

Fair ranking tasks, which ask to rank a set of items to maximize utility subject to satisfying group-fairness constraints, have gained significant interest in the Algorithmic Fairness, Information Retrieval, and Machine Learning literature.

Fair Active Ranking from Pairwise Preferences

no code implementations5 Feb 2024 Sruthi Gorantla, Sara Ahmadian

Our proposed objective function asks to minimize the $\ell_q$ norm of the error of the groups, where the error of a group is the $\ell_p$ norm of the error of all the items within that group, for $p, q \geq 1$.
