pipeline.match(X_train, y_train)

16. Consider the perfect mannequin with a number of metrics.

  • We consider the efficiency of the optimized mannequin on the check set utilizing the identical efficiency metrics as earlier than (accuracy, precision, recall, and F1-score). This lets you examine the efficiency of the optimized mannequin with the preliminary mannequin.
  • We save every of the scores of the tuned mannequin on our Neptune run.
y_pred = pipeline.predict(X_test)
accuracy = accuracy_score(y_test, y_pred)
precision = precision_score(y_test, y_pred)
recall = recall_score(y_test, y_pred)
f1 = f1_score(y_test, y_pred)

run["accuracy_tuned"] = accuracy
run["precision_tuned"] = precision
run["recall_tuned"] = recall
run["f1_tuned"] = f1

  • In case you run this code and look solely on the efficiency of those metrics, we would suppose that the tuned mannequin is worse than earlier than. Nonetheless, when you have a look at the imply cross-validated rating, a extra strong method to consider your mannequin, you’ll understand that the tuned mannequin performs nicely on the entire dataset, making it extra dependable.

y_pred = pipeline.predict(X_test)

report = classification_report(y_test, y_pred, output_dict=True)
for label, metrics in report.objects():
    if isinstance(metrics, dict):
        for metric, worth in metrics.objects():
            run[f'classification_report/{label}/{metric}'] = worth
        run[f'classification_report/{label}'] = metrics

conf_mat = confusion_matrix(y_test, y_pred)
conf_mat_plot = px.imshow(conf_mat, labels=dict(x="Predict", y="Goal"), x=[x+1 for x in range(len(conf_mat[0]))], y=[x+1 for x in range(len(conf_mat[0]))])
