Supervised Machine Learning - Crash Course Statistics

Adriene Hill introduces machine learning in statistics, focusing on predicting future data. She explains supervised learning models like logistic regression, linear discriminant analysis (LDA), and k-nearest neighbors (k-NN). Logistic regression predicts probabilities, LDA uses Bayes' theorem for classification, and k-NN classifies based on proximity to data points. The video emphasizes the importance of testing models with unseen data and discusses accuracy and dimensionality reduction. Machine learning's role in handling large data sets and its everyday applications are highlighted.
