"WebConvert categorical variable into dummy/indicator variables and drop one in each category: X = pd.get_dummies (data=X, drop_first=True) So now if you check shape of X with drop_first=True you will see that it has 4 columns less - one for each of your categorical variables. You can now continue to use them in your linear model. " - Normalizing variables in regression

Web11 de nov. de 2024 · A technique to scale data is to squeeze it into a predefined interval. In normalization, we map the minimum feature value to 0 and the maximum to 1. Hence, the feature values are mapped into the [0, 1] range: In standardization, we don’t enforce the data into a definite range. Instead, we transform to have a mean of 0 and a standard … Web16 de fev. de 2024 · Second there are two general classes of machine learning problems: classification and regression.
