Explain

Sensitivity analysis

Perform sensitivity analysis to identify feature relevances

sensitivity_analysis(model, dataset[, std, ...])	Perform a sensitivity analysis using the partial derivatives method.
plot_sensitivity(results[, mode, per_class, ...])	Plot results of the sensitivity analysis.

Sparse linear model

Use sparse models to approximate classification/regression tasks

lasso_classification(dataset[, ...])	Perform sparse classification via LASSO on a given DictDataset (requires keys: "data" and "labels").
lasso_regression(dataset[, alphas, ...])	Perform sparse regression via LASSO on a given DictDataset (requires keys: "data" and "target").
plot_lasso_classification(classifier[, ...])	Plot results of the LASSO classification.
plot_lasso_regression(regressor[, feats, ...])	Plot the results of the LASSO regression.
