Another way to normalize the input features/variables (apart from the standardization that scales the features so that they have μ=0and σ=1) is the Min-Max scaler. By doing so, all features will be transformed into the range [0,1] meaning that the minimum and maximum value of a...
Now that we have those values we can normalize our averages from table 1. So we do : (value-min)/(max-min) Table 3: John Karl Anna Speed 1 1 0 Stamina 1 0 0.89 We then do the same thing for value 2 which gives use another set of normalized values. I hope it's clearer, tha...
