You would expect the high age
high hours-per-week
to be "high-earning". This is what the 2d plot shows (in red). The plot_tree
(tree diagram) says value = [637, 572]
so in the same order as all the other leaves.
Not clear where the problem is, plot_tree
(scikit-learn) or plot_tree_decision_function
(function in the notebook).
Maybe instead we could have a CI job that check that the notebook render without errors and another CI jobs that run the rendering of the notebooks only on merge commits in master and commits and push the results into a dedicated "rendered" branch that we then use for nbviewer links. We could also render the HTML to make the rendered notebooks directly browsable as a website on https://lesteve.github.io/scikit-learn-tutorial
This way we would never have the diff with spurious output changes in pull request.
WDYT?
I have some minor suggestions:
01_tabular_data_exploration:
adult_census.profile_report()
tells us that there are a few duplicate rows. It may be worthwhile explaining how these duplicate entries may affect/not affect prediction?02_basic_preprocessing
StandardScaler
does? Maybe not everyone knows the equation?04_basic_parameters_tuning:
C
. Maybe even just give them a useful link to read on regularisation and overfitting?model = make_pipeline(
preprocessor, LogisticRegressionCV(max_iter=1000, solver='lbfgs', cv=5)
)
score = cross_val_score(model, data, target, n_jobs=4, cv=5)
you don't provide a Cs
argument like you do above and it might be worth mentioning that by default it tests a grid of 10 C
values.
https://github.com/lesteve/scikit-learn-tutorial/runs/315274429. This has failed for a few days see https://github.com/lesteve/scikit-learn-tutorial/actions. There seems to be a TimeoutError, the PDF export takes 50s and does not complete. Maybe there is a timeout that can be increased with github actions ? ping @brospars.

This is not very structured, so feel free to edit, comment, open other issues for bigger chunks of work:
