python min_max_scaler

The `MinMaxScaler` is a data preprocessing technique used for feature scaling in machine learning. It scales the values of a feature to a given range, typically from 0 to 1.

The `MinMaxScaler` function is available in the `sklearn.preprocessing` module in Python. Here's an example of how to use it:

from sklearn.preprocessing import MinMaxScaler

# create an instance of the scaler
scaler = MinMaxScaler()

# fit the scaler to the data and transform it
scaled_data = scaler.fit_transform(data)

In the code above, `data` is the data that we want to scale. We create an instance of the `MinMaxScaler` and then fit it to the data using the `fit_transform` method. This method scales the data and returns the scaled data as a numpy array.

The `MinMaxScaler` works by subtracting the minimum value of the feature and then dividing by the range (the difference between the maximum and minimum values). This ensures that the minimum value of the feature is scaled to 0 and the maximum value is scaled to 1.
