Title: Heuristic learning on the border between success and failure Abstract: Many popular hypothesis classes, such as neural-networks or decision trees, are computationally hard to learn. In practice, however, heuristic algorithms are used to learn these classes with remarkable success. To better understand this gap, we explore probabilistic models where a small change in the ...

Title: Second-order Optimization Made Practical Abstract: Optimization in machine learning, both theoretical and applied, is presently dominated by first-order gradient methods such as stochastic gradient descent.  Higher-order (preconditioned) optimization methods have become far less prevalent, despite compelling theoretical properties, due to their impractical computation, memory and communication costs.  I will present some recent theoretical, algorithmic ...
