Abstract NOMENCLATURE I.INTRODUCTION A.Learning from Data 未完待续 Abstract Multilayer Neural Networks trained with the backpropagation algorithm constitute the best example of a successful Gradient-Based Learning technique. Given an appropriate network architecture, Gradient-Based Learning algorithms can be ...
In this paper, we use an intuitive gradient-based algorithm to select a preferred action. The algorithm is developed in the reinforcement learning paradigm, where the reward as a feedback from the environment is modeled by the gradient of the features and the value of actions are estimated ...

1. Sequential Ensemble Learning It is a boosting technique where the outputs from individual weak learners associate sequentially during the training phase. The performance of the model is boosted by assigning higher weights to the samples that are incorrectly classified. AdaBoost algorithm is an examp...

It says there's a big problem with recurrent nets and a wider class of learning machines and what is the problem? So you digging into fundamentally what is going on and doing experiments whose purpose was not to compare algorithm A with algorithm B, but really answer the question of what'...
