Two new research papers explore the computational hardness of learning with halfspaces under Gaussian distributions. The first paper focuses on homogeneous halfspaces, proving near-optimal hardness results under the Learning With Errors assumption and extending prior work to this specific case. The second paper provides improved hardness results for learning intersections of halfspaces, offering unconditional bounds in the statistical query framework and narrowing the gap between upper and lower bounds for learning multiple halfspaces.
