Web7 jan. 2024 · 4 Answers. Normalization across instances should be done after splitting the data between training and test set, using only the data from the training set. This is because the test set plays the role of fresh unseen data, so it's not supposed to be accessible at the training stage. Using any information coming from the test set before … WebWhen you are training a Supervised Machine Learning model, such as a Support Vector Machine or Neural Network, it is important that you split your dataset into at least a training dataset and a testing dataset. This can be done in many ways, and I often see a variety of manual approaches for doing this.
