You need to normalize a NumPy array so that the values range between 0 and 1. How would you achieve this?

  • Using Exponential Transformation: np.exp(arr)
  • Using Min-Max Scaling: (arr - arr.min()) / (arr.max() - arr.min())
  • Using Square Root Transformation: np.sqrt(arr)
  • Using Standardization: (arr - arr.mean()) / arr.std()
To normalize a NumPy array to the range [0, 1], you should use Min-Max Scaling. It involves subtracting the minimum value of the array from each element and then dividing by the range (the difference between the maximum and minimum values). This method scales the data linearly to the desired range.
