F1-Score The F1 Score is a metric used to evaluate the performance of a classification model by combining both precision and recall into a single score. It provides a balance between precision and recall, especially when there is an uneven class distribution or when both false positives and false negatives …
Read More »Precision Score
Precision Score Precision Score is a metric used in classification tasks to measure how many of the positive predictions made by a model are actually correct. In simpler terms, it answers the question: Out of all the instances the model predicted as positive, how many were truly positive? The formula …
Read More »Recall Score
Recall Score The Recall Score (also known as Sensitivity or True Positive Rate) measures the ability of a classification model to correctly identify all relevant (positive) instances. In other words, it answers the question: Out of all the actual positive cases, how many did the model correctly predict? The formula …
Read More »Accuracy, Precision, Recall, and F1-Score
Accuracy, Precision, Recall, and F1-Score Accuracy, precision, recall, and F1-score are commonly used performance metrics to evaluate the effectiveness of a classification model. These metrics provide insights into different aspects of the model’s performance in predicting class labels. Here’s a brief explanation of each metric: 1. Accuracy: Accuracy measures the …

K-NN K-Nearest Neighbors (K-NN) is a simple machine learning algorithm used for both classification and regression tasks. It’s based on the idea that things that are similar to each other are likely to be in the same category. Key Concepts of K-NN:¶ What is K-NN? K-NN is an algorithm that …
Read More »Naive Bayes Classification
Naive Bayes Naive Bayes is a simple but powerful machine learning algorithm used for classification tasks. It’s based on applying Bayes’ Theorem with the assumption that features are independent of each other, which is why it’s called “naive.” Key Concepts of Naive Bayes:¶ What is Naive Bayes? Naive Bayes is …

Logistic Regression Logistic Regression is a method used in machine learning to predict if something belongs to one of two categories, like “Yes” or “No.” Key Ideas:¶ What does it do? Logistic regression helps answer questions like, “Will a customer buy this product?” or “Is this email spam?” It takes …
