摘要

在本文中，我们提供了一种新的方法来分析标签切换的动力学模型，该模型用于可以在不同能量景观中在梯度流之间随机切换的粒子系统。除了生物学和物理学中的问题，我们还证明了随机梯度下降，机器学习中最流行的技术，在考虑时间连续变量时，可以在这种情况下被理解。我们的分析集中在外部势集合的演化情况下，为此我们提供了关于演化以及平稳问题的分析和数值结果。

Analysis of kinetic models for label switching and stochastic gradient descent

In this paper we provide a novel approach to the analysis of kinetic models for label switching, which are used for particle systems that can randomly switch between gradient flows in different energy landscapes. Besides problems in biology and physics, we also demonstrate that stochastic gradient descent, the most popular technique in machine learning, can be understood in this setting, when considering a time-continuous variant.Our analysis is focusing on the case of evolution in a collection of external potentials, for which we provide analytical and numerical results about the evolution as well as the stationary problem.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
