A New Perspective on Adversarial PerturbationsFrontiers of Deep Learning 20192019-07-15
Claim: adversarial examples come from non-robust features in the data that reliably predict labels but flip under tiny perturbations. Specific experiment…

Is AI human-ready?O'Reilly Artificial Intelligence Conference 2019 - New York, New York2019-04-15
State-of-the-art classifiers flip from “pig” to “airliner” with 99% confidence after a small, carefully chosen noise pattern, and MIT students print a turtle…

Interior Point Methods 1Bridging Continuous and Discrete Optimization Boot Camp 20172017-08-21
Lecture claims simple Newton-style primal‑dual schemes solve LP by following the central path and driving the duality gap mu to zero, using only linear solves…

Interior Point Methods 2Bridging Continuous and Discrete Optimization Boot Camp 20172017-08-21
Covers concrete algorithms and guarantees: path-following Newton steps on the log barrier give the usual sqrt(n) iteration bound for short-step primal‑dual…

Interior Point Methods 3Bridging Continuous and Discrete Optimization Boot Camp 20172017-08-21
Derives a path-following interior‑point method that minimizes the barrier f_mu = (c^T x)/mu + sum_j -log(slack_j) using Newton steps in the local Hessian norm…

Interior Point Methods 4Bridging Continuous and Discrete Optimization Boot Camp 20172017-08-21
Claims an interior-point framework that gets sqrt(d) iterations while keeping each step as cheap as a projection-based Newton solve, yielding runtimes about…
