• Visualize your data with Facets | Yufeng G - Towards Data Science

Facets contains two robust visualizations to aid in understanding and analyzing machine learning datasets.

• Facets Overview - get a sense of the shape of each feature of your dataset
• Facets Dive - explore individual observations

Facets Overview

Overview takes input feature data from any number of datasets, analyzes them feature by feature and visualizes the analysis. Overview gives users a quick understanding of the distribution of values across the features of their dataset(s). Uncover several uncommon and common issues such as unexpected feature values, missing feature values for a large number of observation, training/serving skew and train/test/validation set skew.

Facets Dive

Dive is a tool for interactively exploring large numbers of data points at once. Dive provides an interactive interface for exploring the relationship between data points across all of the different features of a dataset. Each individual item in the visualization represents a data point. Position items by "faceting" or bucketing them in multiple dimensions by their feature values. Success stories of Dive include the detection of classifier failure, identification of systematic errors, evaluating ground truth and potential new signals for ranking.
