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.

CHAPTER Logistic Regression

4.An algorithm for optimizing the objective function. We introduce the stochas-tic gradient descent algorithm. Logistic regression has two phases: training: we train the system (specifically the weights w and b) using stochastic gradient descent and the cross-entropy loss. test: Given a test example x we compute p(yjx) and return the higher ...

Rectified Linear Units Improve Restricted Boltzmann Machines

RBMs were originally developed using binary stochas-tic units for both the visible and hidden layers (Hinton, 2002). To deal with real-valued data such as the pixel intensities in natural images, (Hinton & Salakhutdinov, 2006) replaced the binary visible units by linear units with independent Gaus-sian noise as first suggested by (Freund ...

The paper [3] shows a Frank-Wolfe method for the structured SVM, and derive a stochas-tic block coordinate descent method.

posterior inference. However, the parameters of the VAE can be estimated efficiently in the stochas-tic gradient variational Bayes (SGVB) [16] framework, where the variational lower bound of the log-likelihood is used as a surrogate objective function. The variational lower bound is written as: logp (x) = KL(q ˚(zjx)kp (zjx))+E q ˚(zjx) logq ...
