Genetic Algorithm is a division of machine learning, where the computers are programmed to teach themselves to complete the given task over time. In our project, we simulate many rockets to fly towards the targe
In machine learning (ML), a gradient is a vector that gives the direction of the steepest ascent of the loss function. Gradient descent is an optimization algorithm that is used to train complex machine learning and deep learning models. The cost function within gradient descent measures the acc...

alpha: Initial step size (learning rate), a typical value is 0.001. beta1: Decay factor for first momentum, a typical value is 0.9. beta2: Decay factor for infinity norm, a typical value is 0.999. And that’s it. For full derivation of the Adam algorithm in the context of the Adam...
The learning algorithm’s job is to find from the training examples a correlation between the feature values and the optimal optimization decision. The learned model can then be used to predict, for a new set of features, what the optimal optimization option should be.Because the performance of...

DSMs are the control layout in these grids, and they aim at optimizing loads in various ways. The SMG includes batteries and distributed photovoltaics. This paper combines an Elephant Herding optimization algorithm (EHOA) and support sector machine (SVM) to the decision-making method in batteries...
4.1.2. Nonconvex Optimization in the Deep Neural Networks 有两种思路解决这一问题,一种是将非凸优化问题松弛化为凸优化问题,再用凸优化算法解决;另一种是直接解决非凸优化问题,包括projection gradient descent,expectation maximization algorithm等方法。 4.2. Difficulties in Sequential Models with Large-Scale Da...
