A convex optimization model predicts an output from an input by solving a convex optimization problem. The class of convex optimization models is large, and includes as special cases many well-known models like linear and logistic regression. We propose a heuristic for learning the parameters in ...
The idea is to describe user comfort zone by a Convex Piecewise Linear Classifier (CPLC), which is directly pluggable for the optimization in MPC. We analyze the theoretical generalization performance of the classifier and propose a cost sensitive large margin learning formulation. The learning ...
博士刚开始主要接触了很多Numerical optimization, Convex optimization,Nonlinear programming的知识,用来解决实际工业过程中的优化问题。随着近几年来,人工智能机器学习火了起来,逐渐研究的重心也从数学优化转到机器学习相关领域了,但是我一直还是认为优化是自己的老本行,也一直从优化的角度去看待机器学习的问题去尝试做一些...
predictive models for energy consumption including Markov’s decision process and NN’s can be incorporated with IoT- enabled devices [8]. 补充说明一下,为啥我觉得本文作者写的文章引用量太少;下面这么多篇幅的内容,却没有引用相关文献。 support vector machine (SVM) provides effective data classification...
REINFORCEMENT LEARNING FOR LINEAR-CONVEX MODELS WITH JUMPS VIA STABILITY ANALYSIS OF FEEDBACK CONTROLS We study finite-time horizon continuous-time linear-convex reinforcement learning problems in an episodic setting. In this problem, the unknown linear jump... X Guo,A Hu,Y Zhang - 《Siam Journal...

This is especially true of algorithms that operate in high-dimensional spaces or that train non-linear models such as tensor models and deep networks. The freedom to express the learning problem as a non-convex optimization problem gives immense modeling power to the algorithm designer, but often...
Technically, Tangram is based on nonconvex optimization (Methods), in which the Tangram optimization function rewards the spatial alignment of sc/snRNA-seq data using two similarity functions: cell-density distributions are compared using Kullback–Leibler (KL) divergence, whereas gene expression is ass...
Training Many Similar Models A Single Value Structure 用计数去替换学习率的计算中的累计梯度,可以又快又省。 对负样本重采样。但会改变数据分布,所以可以给重采样的样本加上权重。 具体细节可以看这篇文章:各大公司广泛使用的在线学习算法FTRL详解 ,讲的很好,细节不再赘述。也可以直接看原论文:Ad Click Predicti...
