I am always studying.
I'm trying Deep Q learning with Chainerrl.
Tell me about data standardization.
If a continuous variable takes a value between -10 or less and 10 or more across 0 as shown in the following list:
How should we standardize it?
Since we are going to use it with nominal variables separated by (0, 1), we want to make the values of other continuous variables also in the range of 0 to 1. What should I do?
Although it seems that the values are almost in the range of -10 to 10, the exact value is the minimum and maximum values.
Should I normalize -10 or less as -10 and 10 or more as 10?

Mathematically, if you want to change from -10 to 10 from 0 to 1, you will have to translate by a factor of 20 times from -0.5 to 0.5 and then the whole translation by 0.5.
I just feel that it has a standardized function.
If you don't know the maximum and minimum values, you can find each data.
