WebDec 27, 2024 · These coefficients can provide the basis for a crude feature importance score. This assumes that the input variables have the same scale or have been scaled prior to fitting a model. What about Bert? Can we get coef_ variable from the model and use it to calculate feature importance like LinearRegression model in text classification task? nlp WebFeature importance provides a highly compressed, global insight into the model’s behavior. A positive aspect of using the error ratio instead of the error difference is that the feature importance measurements are comparable across different problems. The importance measure automatically takes into account all interactions with other features.
