Those negative values are negative because you compute them previously so

I don't quite understand what you mean by this sentence, so the value I calculated at the beginning is negative? Also, I want to ask how should I get rid of my max min value?

Normalization can mean many things. What do you mean by it here and give specific examples.

Your responses suggest that you think negative values are an error. If so why are you asking about normalization and not fixing the error?

As said you end in a range of ]0..1] after you have normalized your rewards.

You can

  • filter negative values.
  • never compute negative values.
  • add an offset to your not normalized values to receive only an unsigned range.

After you have learned so much more in the past few month, it is a good idea to build a new model instead of adjusting your current working model now. This seems weird, but in fact you will build a different model, because you can consider your better knowledge.
