Class-Balanced Loss Based on Effective Number of Samples

and large-scale datasets including ImageNet and iNatural-ist. Our results show that when trained with the proposed class-balanced loss, the network is able to achieve signifi-cant performance gains on long-tailed datasets. 1.

LECTURE NOTES ON APPLIED MATHEMATICS

Jun 17, 2009 · Introduction The source of all great mathematics is the special case, the con-crete example. It is frequent in mathematics that every instance of a concept of seemingly great generality is in essence the same as a small and concrete special case.1 We begin by describing a rather general framework for the derivation of PDEs

Optimal Control Theory - homes.cs.washington.edu

Equations (1, 3, 4) generalize to the stochastic case in the same way as equation (2) does. An optimal control problem with discrete states and actions and probabilistic state transitions is called a Markov decision process (MDP).
