End-to-End Machine Learning: model selection in R using summary results When training multiple machine learning models, it’s important to select the best one to use on new, unseen data. One way to do this is by using a tabular method called “summary results”. Summary results are a collection of statistics that summarize the performance of …
End-to-End Machine Learning: roc metric in R When training a machine learning model, it’s important to evaluate its performance to understand how well it will work on new, unseen data. One common way to evaluate the performance of a model for binary classification problems is by using a metric called “Receiver Operating Characteristic” (ROC) curve. …
End-to-End Machine Learning: kappa metric in R When training a machine learning model, it’s important to evaluate its performance to understand how well it will work on new, unseen data. One common way to evaluate the performance of a model is by using a metric called “kappa.” Kappa is a measure of the agreement between …
Evaluate Machine Learning Algorithm – leave one out cross validation in R Evaluating the performance of a machine learning algorithm is an important step in understanding how well it will work on new, unseen data. One popular method for evaluating the performance of an algorithm is called “leave-one-out cross validation” (LOOCV). In leave-one-out cross validation, …
Classification in R – SVM in R Support Vector Machine (SVM) is a popular method for classification in machine learning and data analysis. It’s a type of algorithm that can sort items into different categories based on their characteristics. An SVM works by finding the best boundary, or “decision boundary,” that separates the different classes …
