Mini-batch $k$ -means terminates within $O (d / ε)$ iterations

Gregory Schwartzman

We answer the question: "Does local progress (on batches) imply global progress (on the entire dataset) for mini-batch $k$ -means?". Specifically, we consider mini-batch $k$ -means w…

SGD Through the Lens of Kolmogorov Complexity

Gregory Schwartzman

We prove that stochastic gradient descent (SGD) finds a solution that achieves $(1 - ε)$ classification accuracy on the entire dataset. We do so under two main assumptions: (1. Local…
