AUC ROC Curve in Machine Learning

Evaluating machine learning models, especially for classification tasks, goes beyond measuring just accuracy. In real-world scenarios—such as fraud detection, medical diagnosis, or spam filtering—datasets are often imbalanced, making accuracy an unreliable metric. This is where the AUC-ROC Curve becomes essential. It provides a comprehensive view of a model’s ability to distinguish between classes across various ...

lasso regression

What is Lasso Regression?

Lasso Regression, short for Least Absolute Shrinkage and Selection Operator, is a linear regression technique that enhances prediction accuracy and model interpretability by performing both variable selection and regularization. Unlike traditional linear regression, which can overfit data when too many features are involved, Lasso adds a penalty to the regression equation to shrink some coefficients ...

generalization in machine learning

What is Generalization in Machine Learning?

Generalization in machine learning refers to a model’s ability to perform well on new, unseen data after being trained on a specific dataset. It determines how effectively a model applies learned patterns to make accurate predictions beyond the training data. A well-generalized model captures meaningful relationships within the data, ensuring reliability across different scenarios. However, ...
