ROC Curve Explained using a COVID-19 hypothetical example: Binary & Multi-Class Classification… In this post I clearly explain what a ROC curve is and how to read it. I use a COVID-19 example to make my point and I… towardsdatascience.com Support Vector Mach...
How to make both class and probability predictions with a final model required by the scikit-learn API. How to calculate precision, recall, F1-score, ROC AUC, and more with the scikit-learn API for a model. Kick-start your project with my new book Deep Learning With Python, including...
This can be achieved using statistical techniques where the training dataset is carefully used to estimate the performance of the model on new and unseen data. In this tutorial you will discover how you can evaluate the performance of your gradient boosting models with XGBoost in Python. After co...
In other words, if you randomly select one observation from each class, what’s the probability that your model will be able to “rank” them correctly? We can import this metric from Scikit-Learn: Python 1 from sklearn.metrics import roc_auc_score To calculate AUROC, you’ll need predi...
Finally, the other tabs in this view show information about performance details (confusion matrix, precision recall curve, ROC curve), artifacts used for inputs and generated during the AutoML job, and network details. To get mo...
LIME in Python We will now use LIME to explain thevaderSentimentmodel. First, install and import both modules: # Install dependencies!pip install lime!pip install vaderSentiment# Import vader model and LIME for textfrom vaderSentiment.vaderSentiment import SentimentIntensityAnalyzerfrom lime.lime_text...
Because the optimal set of hyperparameters can go a long way to significantly boost the performance of your models. In this article, you will learn how to perform hyperparameter tuning of the random forest model in Python using the scikit-learn library. ...
Now the prediction of the base random forest model was used to obtain the classification report and also to evaluate the AUC score. from sklearn.metrics import classification_report,accuracy_score,roc_auc_score print('Classification report \n',classification_report(Y_test,rfc_pred)) ...

ROC Curve provides a comprehensive visual representation of a classifier's performance at all thresholds, letting analysts choose a threshold that balances sensitivity and specificity according to the business context. Lift Curve focuses more on the effectiveness of a predictive model in terms of "lifti...
