This paper shows how to quantify and test for the information flow between two time series with Shannon transfer entropy and Rényi transfer entropy using the R package RTransferEntropy. We discuss the methodology, the bias correction applied to calculate effective transfer entropy and outline how to...
ENTROPYDEEP learningThis paper explores the application of Transfer Entropy (TE) in deep neural networks as a tool to improve training efficiency and analyze causal information flow. TE is a measure of directed information transfer that captures nonlinear dependencies and temporal dynamics between sys...

迁移学习(Transfer Learning)是一种机器学习方法,就是把为任务 A 开发的模型作为初始点,重新使用在为任务 B 开发模型的过程中。迁移学习是通过从已学习的相关任务中转移知识来改进学习的新任务,虽然大多数机器学习算法都是为了解决单个任务而设计的,但是促进迁移学习的算法的开发是机器学习社区持续关注的话题。 迁移学...
