F-Beta Score in Machine Learning

F-Beta Score in Machine Learning

F-beta is the weighted harmonic mean of the precision and recall. It is used as a performance evaluation measure for classification-based machine learning models. If you’ve never used this performance measurement metric before to evaluate your classification models, this article…

Calculation of Accuracy using Python

Calculation of Accuracy using Python

In machine learning, accuracy is one of the most important performance evaluation metrics for a classification model. The mathematical formula for calculating the accuracy of a machine learning model is 1 – (Number of misclassified samples / Total number of…

R2 Score in Machine Learning

R2 Score in Machine Learning

The R2 score is one of the performance evaluation measures for regression-based machine learning models. It is also known as the coefficient of determination. If you want to learn how to evaluate the performance of a machine learning model using…

Evaluate a Machine Learning Model

Evaluate a Machine Learning Model

When you make an accurate prediction using your trained Machine Learning model, then the next step is often to measure the performance of your model. Data Scientists and other Machine Learning Experts spend a larger part to evaluate a Machine…

ROC Curve in Machine Learning

The Receiver Operating Characteristic (ROC) curve is a popular tool used with binary classifiers. It is very similar to the precision/recall curve. Still, instead of plotting precision versus recall, the ROC curve plots the true positive rate (another name for…

Precision and Recall

In Machine Learning, Precision and Recall are the two most important metrics for Model Evaluation. Precision represents the percentage of the results of your model, which are relevant to your model. The recall represents the percentage total of total pertinent…
