Feature extraction gardenEdit
When supporting an ecosystem with multiple models that use similar features, it's important that features are (1) well defined and (2) don't duplicate work. #Feature dependencies depicts a set of example features, their dependencies on datasources and other features. By using a dependency injection strategy for specifying and actualizing relationships between features/datasources, we can allow for easy development of new features based on old features and datasources. We can also minimize the work that the system will need to perform when building feature sets for a large set of different models.
