[PDF][PDF] Fast rates in statistical and online learning

T Van Erven, PD Grünwald, NA Mehta, MD Reid… - The Journal of Machine …, 2015 - jmlr.org
The speed with which a learning algorithm converges as it is presented with more data is a
central problem in machine learning—a fast rate of convergence means less data is needed …

[PDF][PDF] Enhanced safety and efficacy of protease-regulated CAR-T cell receptors

…, P Xu, JH Hui, T Murty, J Theruvath, N Mehta… - Cell, 2022 - cell.com
Regulatable CAR platforms could circumvent toxicities associated with CAR-T therapy, but

Fast rates for general unbounded loss functions: from ERM to generalized Bayes

PD Grünwald, NA Mehta - Journal of Machine Learning Research, 2020 - jmlr.org
We present new excess risk bounds for general unbounded loss functions including log
loss and squared loss, where the distribution of the losses may be heavy-tailed. The bounds …

[PDF][PDF] Structure and functional binding epitope of V-domain Ig suppressor of T cell activation

N Mehta, S Maddineni, II Mathews, RAP Sperberg… - Cell reports, 2019 - cell.com
V-domain immunoglobulin (Ig) suppressor of T cell activation (VISTA) is an immune checkpoint
