PCA for feature exploration
You'll use the PCA pipeline you've built in the previous exercise to visually explore how some categorical features relate to the variance in poke_df
.
These categorical features (Type
& Legendary
) can be found in a separate DataFrame poke_cat_df
.
All relevant packages and classes have been pre-loaded for you (Pipeline()
, StandardScaler()
, PCA()
)

Dimensionality Reduction in Python
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Build the pipeline
pipe = Pipeline([('scaler', StandardScaler()),
('reducer', PCA(n_components=2))])
# Fit the pipeline to poke_df and transform the data
pc = ____
print(pc)
