A Comparative Analysis of Retrievability and PageRank Measures

no code implementations17 Nov 2023 Aman Sinha, Priyanshu Raj Mall, Dwaipayan Roy

Metrics such as PageRank, Hub, and Authority illuminate the pathways through which documents can be discovered within the network of content while the concept of Retrievability is used to quantify the ease with which a document can be found by a retrieval model.

Embedding Synthetic Off-Policy Experience for Autonomous Driving via Zero-Shot Curricula

no code implementations2 Dec 2022 Eli Bronstein, Sirish Srinivasan, Supratik Paul, Aman Sinha, Matthew O'Kelly, Payam Nikdel, Shimon Whiteson

However, this approach produces agents that do not perform robustly in safety-critical settings, an issue that cannot be addressed by simply adding more data to the training set - we show that an agent trained using only a 10% subset of the data performs just as well as an agent trained on the entire dataset.

Efficient Black-box Assessment of Autonomous Vehicle Safety

2 code implementations8 Dec 2019 Justin Norden, Matthew O'Kelly, Aman Sinha

Using this framework, we conduct the first independent evaluation of a full-stack commercial AV system, Comma AI's OpenPilot.

In-silico Risk Analysis of Personalized Artificial Pancreas Controllers via Rare-event Simulation

no code implementations2 Dec 2018 Matthew O'Kelly, Aman Sinha, Justin Norden, Hongseok Namkoong

Modern treatments for Type 1 diabetes (T1D) use devices known as artificial pancreata (APs), which combine an insulin pump with a continuous glucose monitor (CGM) operating in a closed-loop manner to control blood glucose levels.

Scalable End-to-End Autonomous Vehicle Testing via Rare-event Simulation

1 code implementation NeurIPS 2018 Matthew O'Kelly, Aman Sinha, Hongseok Namkoong, John Duchi, Russ Tedrake

While recent developments in autonomous vehicle (AV) technology highlight substantial progress, we lack tools for rigorous and scalable testing.

Catalog of Formalized Application Integration Patterns

1 code implementation6 Jul 2018 Daniel Ritter, Stefanie Rinderle-Ma, Marco Montali, Andrey Rivkin, Aman Sinha

Enterprise application integration (EAI) solutions are the centrepiece of current enterprise IT architectures (e. g., cloud and mobile computing, business networks), however, require the formalization of their building blocks, represented by integration patterns, verification and optimization.

Certifying Some Distributional Robustness with Principled Adversarial Training

1 code implementation ICLR 2018 Aman Sinha, Hongseok Namkoong, Riccardo Volpi, John Duchi

Neural networks are vulnerable to adversarial examples and researchers have proposed many heuristic attack and defense mechanisms.

Adaptive Sampling Probabilities for Non-Smooth Optimization

no code implementations ICML 2017 Hongseok Namkoong, Aman Sinha, Steve Yadlowsky, John C. Duchi

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.

Learning Kernels with Random Features

1 code implementation NeurIPS 2016 Aman Sinha, John C. Duchi

We extend the randomized-feature approach to the task of learning a kernel (via its associated random features).
