New algorithm learns halfspaces without synthetic data

Researchers have developed a new algorithm for learning halfspaces without relying on synthetic data, addressing a long-standing challenge in computational geometry. The algorithm achieves tight bounds of $\Theta(D + \log n)$ for learning halfspaces with normal vectors from a set of size $D$. This approach also yields nearly optimal algorithms for PAC-learning, requiring $O(\min(D + \log(1/\varepsilon), 1/\varepsilon) \cdot \log D)$ queries to learn a function within error $\varepsilon$, even with adversarial corruption.
