New algorithm achieves optimal error for robust Boolean concept learning

Researchers have developed a polynomial-time algorithm for robustly learning Boolean concept classes, improving upon a previous computationally inefficient method. This new algorithm achieves an optimal error rate of $\eta + \varepsilon$, where $\eta$ is the noise rate, by leveraging no-regret learners. Additionally, the paper presents an efficient algorithm for learning any function class that can be sandwiched by hypercontractive distributions, including the first polynomial-time approach for robustly learning half-spaces with respect to Gaussian marginals.
