Facets is an open source visualization tool for machine learning and training data. It has two visualizations for understanding and analyzing machine learning datasets, Facets Overview and Facets Dive.
It provides users understanding of the distribution of values across the features of their datasets. Multiple datasets, such as a training set and a test set, can be compared on the same visualization. It analyzes features and visualizes the analysis.
Facets visualizations are implemented as Polymer web components and backed by Typescript code and can be easily embedded into Jupyter notebooks or webpages.
