Assumption-lean logistic regression with missing covariates
Jyotishka Ray Choudhury, Kabir Aladin Verchand, Richard J. Samworth +1
Missing covariates are frequently encountered in supervised learning problems, and classical methods for estimation using such data use carefully chosen imputation schemes for miss…
Signal recovery in the polychromatic computed tomography model: Injectivity and complexity
Xuanzhou Chen, Ashwin Pananjady
We consider a nonlinear model motivated by polychromatic computed tomography (CT). Here, distinct -dimensional signals must be recove…
Toward individual-level calibration in affect recognition with perceptual adjustment queries
Xuanzhou Chen, Sankaraleengam Alagapan, Ashwin Pananjady
Behavioral tasks measuring facial affect perception assume that identical stimuli impose equivalent perceptual difficulty across participants. However, this assumption is systemati…
Next-token functional estimation
Milind Nakul, Vidya Muthukumar, Ashwin Pananjady
Suppose we observe the first points of a sequence of random variables having length , and wish to estimate a functional of the unobserved final point and the empirical mea…
Leave a Window Out: Modifying the Jackknife for Predictive Inference in Time Series
Hanyang Jiang, Rina Foygel Barber, Ashwin Pananjady +1
Conformal prediction methods enjoy strong theoretical and empirical predictive inference performance, provided the data is exchangeable and is treated symmetrically during training…
Instance-optimal stochastic convex optimization: Can we improve upon sample-average and robust stochastic approximation?
Liwei Jiang, Ashwin Pananjady
We study the unconstrained minimization of a smooth and strongly convex population loss function under a stochastic oracle that introduces both additive and multiplicative noise; t…
