Recent questions
What is supervised learning?
Supervised learning involves using labeled data to predict new labels. Tasks include classification (predicting discrete classes) and regression (predicting continuous values).
How does logistic regression differ from linear regression?
Logistic regression estimates probabilities between 0 and 1 for classification tasks, transforming probabilities using the odds ratio and log of odds.
What is the purpose of K Nearest Neighbors (KNN)?
K Nearest Neighbors (KNN) predicts a point's label based on its proximity to other points, extending to higher dimensions by considering multiple features.
What is the role of Principal Component Analysis (PCA) in unsupervised learning?
PCA helps reduce data dimensions to increase discrimination between points, projecting data onto dimensions with the largest variance to minimize residuals.
How does neural network training differ from linear regression?
Neural network training involves feeding loss back into the model, adjusting weights using gradient descent, and utilizing activation functions to introduce nonlinearity.
