WitrynaThe effect of changing the maximum and minimum clusters for a running warehouse depends on whether it is running in Maximized or Auto-scale mode: Maximized: ↑ … Witryna23 mar 2024 · In fact, min-max scaling can also be said to a type of normalization. In machine learning, the following are most commonly used. #1 Standardization (also called z-score normalization) transforms your data such that the resulting distribution has a mean of 0 and a standard deviation of 1. It’s the definition that we read in the last …
