Encoding Cyclical Features for Deep Learning

7 years ago 3 min read deep learning data science feature engineering

A key concern when dealing with cyclical features is how we can encode the values such that it is clear to the deep learning algorithm that the features occur in cycles. This post looks at a strategy to encode cyclical features in order to clearly express their cyclical nature.
