StrategyAtlas is a visual analytics system to enable understanding of complex models by identifying and interpreting different model strategies.
What is a model strategy?
- model⋅strategy [ˈmɒdl ˈstratɪʤi]
- different treatments by a machine learning model of distinct groups in the input data.
How do we find data clusters?
Traditionally, we can find clusters in the data by applying a 2D projection technique (e.g., UMAP).
How do we find strategy clusters?
We propose using the same approach on feature importance values to find model strategies.
