WebFigure 1: Our feature importance ranking model. (a) Dual-net architecture. (b) Parameter update. Ideally, an FIR approach should be able to: 1) detect any functional dependence between input features and targets; 2) rank the importance of all the selected features to reﬂect their contributions WebSep 16, 2024 · What you can do though is to derive the feature importance locally, as you can locally approximate the neural network by a linear function. This can be used to explain the behaviour and the feature importance, but only in small neighborhood around the current position. If you go to another position, the behaviour could be completely different!
