Web10 jul. 2024 · Normalization methods: (a) Mapminmax normalization; (b) Mapstd normalization. 4.2. Input feature selection. In order to develop predictive history match machine learning models during the training process, key input variables are needed to form a mapping relationship between the dependent response variables. Web11 dec. 2013 · If you want to normalize every row of your training dataset, the appropriate method is mapminmax method from Neural Network toolbox. If you tend to normalize based on each column (feature), there are too many ways. If your dataset consists of different boundary, it is better to normalize between [-1 1], otherwise [0 1] is appropriate.
