Webb31 aug. 2024 · Let’s wrap things up in the next section. Before you go. That’s pretty much it for data standardization and why it is important. We’ll compare StandardScaler with other scalers some other time. The take-home point of this article is that you should use StandardScalerwhenever you need normally distributed (relatively) features. WebbThere’s a lot of increasing performance just by selecting only important features. What I think is more commonly, the reason to do automatic feature selection is you want to shrink your model to make faster predictions, to train your model faster, to store fewer data and possibly to collect fewer data. If you’re collecting the data or to ...
