In many cases (a differentiable model with a gradient), you can use integrated gradients (IG) to get a more certain and possibly faster explanation of feature importance for a prediction. However, a Shapley-value-based method is required for other (non-differentiable) model types. At Fiddler, we support both SHAP and IG. tabby maths

It assigns importance scores to features by propagating scores from the output of the model back to the input. Similar to integrated gradients, deepLIFT also defines importance scores relative to a baseline, which they call the “reference”.

NettetIn this video, we discuss another attribution method called Integrated Gradients that can be used to explain predictions made by deep neural networks (or any differentiable model for that matter). It can be implemented in a few lines of code, and is much faster than Shapley values.
