Continuous Treatment Effect Estimation Using Gradient Interpolation and Kernel Smoothing

1 code implementation27 Jan 2024 Lokesh Nagalapatti, Akshay Iyer, Abir De, Sunita Sarawagi

The main challenge in this estimation task is the potential confounding of treatment assignment with an individual's covariates in the training data, whereas during inference ICTE requires prediction on independently sampled treatments.

Gradient Coreset for Federated Learning

1 code implementation13 Jan 2024 Durga Sivasubramanian, Lokesh Nagalapatti, Rishabh Iyer, Ganesh Ramakrishnan

We conduct experiments using four real-world datasets and show that GCFL is (1) more compute and energy efficient than FL, (2) robust to various kinds of noise in both the feature space and labels, (3) preserves the privacy of the validation dataset, and (4) introduces a small communication overhead but achieves significant gains in performance, particularly in cases when the clients' data is noisy.

Game of Gradients: Mitigating Irrelevant Clients in Federated Learning

1 code implementation23 Oct 2021 Lokesh Nagalapatti, Ramasuri Narayanam

We follow a principled approach to address the above FRCS problems and develop a new federated learning method using the Shapley value concept from cooperative game theory.

Data Quality Toolkit: Automatic assessment of data quality and remediation for machine learning datasets

no code implementations12 Aug 2021 Nitin Gupta, Hima Patel, Shazia Afzal, Naveen Panwar, Ruhi Sharma Mittal, Shanmukha Guttula, Abhinav Jain, Lokesh Nagalapatti, Sameep Mehta, Sandeep Hans, Pranay Lohia, Aniya Aggarwal, Diptikalyan Saha

We attempt to re-look at the data quality issues in the context of building a machine learning pipeline and build a tool that can detect, explain and remediate issues in the data, and systematically and automatically capture all the changes applied to the data.
