Foveation-based Mechanisms Alleviate Adversarial Examples

2015 · arXiv (Cornell University)

We show that adversarial examples, i.e., the visually imperceptible perturbations that result in Convolutional Neural Networks (CNNs) fail, can be alleviated with a mechanism based on foveations---applying the CNN in different image regions. To see …

Detecting multipartite entanglement structure with minimal resources

2019 · npj Quantum Information

Abstract Recently, there are tremendous developments on the number of controllable qubits in several quantum computing systems. For these implementations, it is crucial to determine the entanglement structure of the prepared multipartite quantum state as …

Quantum coherence via conditional entropy

2018 · Journal of Physics A Mathematical and Theoretical

Abstract Quantum coherence characterizes the non-classical feature of a single party system with respect to a local basis. Based on a recently introduced resource framework, coherence can be regarded as a resource and be systematically …

Learning to Predict Trustworthiness with Steep Slope Loss

2021 · arXiv (Cornell University)

Understanding the trustworthiness of a prediction yielded by a classifier is critical for the safe and effective use of AI models. Prior efforts have been proven to be reliable on small-scale datasets. In this work, …

A Partitioning Method for Gamma Gaussian inverse Wishart Probability Hypothesis Density Filter using Kolmogorov-Smirnov Test

2021 · 2021 2nd International Conference on Artificial Intelligence and Computer Engineering (ICAICE)

In multiple extended objects tracking, objects produce more than one measurement per time step. When objects are spatially close or maneuvering, the performance of typical partitioning methods will be reduced. This paper presents a partitioning …

Distributed Evolution Strategies With Multi-Level Learning for Large-Scale Black-Box Optimization

2024 · IEEE Transactions on Parallel and Distributed Systems

In the post-Moore era, main performance gains of black-box optimizers are increasingly depending on parallelism, especially for large-scale optimization (LSO). Here we propose to parallelize the well-established covariance matrix adaptation evolution strategy (CMA-ES) and in …

PQPU: A 4.4-<i>μ</i>J/Op 69.4-kOPS Agile Post-Quantum Crypto-Processor Across Multiple Mathematical Problems

2024 · IEEE Journal of Solid-State Circuits

Post-quantum cryptography (PQC) is currently being standardized to replace the existing public-key cryptography for data security in the era of quantum computing. PQC algorithms exhibit considerable diversity in their underlying mathematical problems, storage requirements, and …
