Certifying some distributional robustness with principled adversarial training

A Sinha, H Namkoong, R Volpi, J Duchi - arXiv preprint arXiv:1710.10571, 2017 - arxiv.org
Neural networks are vulnerable to adversarial examples and researchers have proposed
many heuristic attack and defense mechanisms. We address this problem through the …

Scalable end-to-end autonomous vehicle testing via rare-event simulation

M O'Kelly, A Sinha, H Namkoong… - Advances in neural …, 2018 - proceedings.neurips.cc
While recent developments in autonomous vehicle (AV) technology highlight substantial
progress, we lack tools for rigorous and scalable testing. Real-world testing, the de facto …

Learning kernels with random features

A Sinha, JC Duchi - Advances in neural information …, 2016 - proceedings.neurips.cc
Randomized features provide a computationally efficient way to approximate kernel machines
in machine learning tasks. However, such methods require a user-defined kernel as input. …

Visualizing the very-large-scale motions in turbulent pipe flow

LHO Hellström, A Sinha, AJ Smits - Physics of Fluids, 2011 - pubs.aip.org
Time-resolved stereoscopic particle image velocimetry is used to investigate the structure of
the very-large-scale motions (VLSMs) in fully developed turbulent pipe flow. The motions …

Efficient black-box assessment of autonomous vehicle safety

J Norden, M O'Kelly, A Sinha - arXiv preprint arXiv:1912.03618, 2019 - arxiv.org
While autonomous vehicle (AV) technology has shown substantial progress, we still lack
tools for rigorous and scalable testing. Real-world testing, the $\textit{de-facto}$ evaluation …

C-net: Contextual network for sarcasm detection

AK Jena, A Sinha, R Agarwal - Proceedings of the second …, 2020 - aclanthology.org
Automatic Sarcasm Detection in conversations is a difficult and tricky task. Classifying an
utterance as sarcastic or not in isolation can be futile since most of the time the sarcastic nature …

Objective measurement of function following lumbar spinal stenosis decompression reveals improved functional capacity with stagnant real-life physical activity

M Smuck, A Muaremi, P Zheng, J Norden, A Sinha… - The Spine Journal, 2018 - Elsevier
Background Context Lumbar spinal stenosis (LSS) is a prevalent and costly condition
associated with significant dysfunction. Alleviation of pain and improvement of function are the …

Neural bridge sampling for evaluating safety-critical autonomous systems

A Sinha, M O'Kelly, R Tedrake… - Advances in Neural …, 2020 - proceedings.neurips.cc
Learning-based methodologies increasingly find applications in safety-critical domains like
autonomous driving and medical robotics. Due to the rare nature of dangerous events, real-…

FormulaZero: Distributionally robust online adaptation via offline population synthesis

A Sinha, M O'Kelly, H Zheng… - International …, 2020 - proceedings.mlr.press
Balancing performance and safety is crucial to deploying autonomous vehicles in multi-agent
environments. In particular, autonomous racing is a domain that penalizes safe but …

Adaptive sampling probabilities for non-smooth optimization

H Namkoong, A Sinha, S Yadlowsky… - … on Machine Learning, 2017 - proceedings.mlr.press
Standard forms of coordinate and stochastic gradient methods do not adapt to structure in
data; their good behavior under random sampling is predicated on uniformity in data. When …
