Agnostic Learning of Halfspaces with Gradient Descent via Soft Margins

Spencer Frei, Yuan Cao, Quanquan Gu

We analyze the properties of gradient descent on convex surrogates for the zero-one loss for the agnostic learning of linear halfspaces. If $OPT$ is the best classificatio…

Agnostic Learning of a Single Neuron with Gradient Descent

Spencer Frei, Yuan Cao, Quanquan Gu

We consider the problem of learning the best-fitting single neuron as measured by the expected square loss $E_{(x, y) \sim D} [(σ (w^{⊤} x) - y)^{2}]$ over some unknown…
