Selective inference using randomized group lasso estimators for general models

no code implementations24 Jun 2023 Yiling Huang, Sarah Pirenne, Snigdha Panigrahi, Gerda Claeskens

Selective inference methods are developed for group lasso estimators for use with a wide class of distributions and loss functions.

Selective Inference for Sparse Multitask Regression with Applications in Neuroimaging

no code implementations27 May 2022 Snigdha Panigrahi, Natasha Stewart, Chandra Sekhar Sripada, Elizaveta Levina

Multi-task learning is frequently used to model a set of related response variables from the same set of features, improving predictive performance and modeling accuracy relative to methods that handle each response variable separately.

Approximate Post-Selective Inference for Regression with the Group LASSO

no code implementations31 Dec 2020 Snigdha Panigrahi, Peter W. MacDonald, Daniel Kessler

After selection with the Group LASSO (or generalized variants such as the overlapping, sparse, or standardized Group LASSO), inference for the selected parameters is unreliable in the absence of adjustments for selection bias.

Causal Structure Discovery from Distributions Arising from Mixtures of DAGs

no code implementations ICML 2020 Basil Saeed, Snigdha Panigrahi, Caroline Uhler

We consider distributions arising from a mixture of causal models, where each model is represented by a directed acyclic graph (DAG).

A relevance-scalability-interpretability tradeoff with temporally evolving user personas

no code implementations25 Apr 2017 Snigdha Panigrahi, Nadia Fawaz

The current work characterizes the users of a VoD streaming space through user-personas based on a tenure timeline and temporal behavioral features in the absence of explicit user profiles.
