I have :
a matrix X with N lines
a vector Y
I've computed the Euclidean distance with Y for each line of X.
What I get is a vector of distances.
What I want is a vector of scores between 0 and 1, 1 meaning "very" high correlation, 0 meaning "no" correlation.
Here what I did :
I divided the vector of distances by the max distance inside it. I get vector D.
1 - D is the final result with values between 0 and 1.
The problem is that I get many values (75%) too close to 1. Do you think what I did is correct ?
How would you get a better result ? (Between 0 and 1 but not everything too close to 1)
For now, I tried to take the square of the result. (To stay between 0 and 1 but to minimize the values)
Here a picture of the distance values I want to turn in a score
