Create a computer vision system using decision tree algorithms to solve a real-world problem : [Activity] Logistic Regre

The video tutorial covers logistic regression, a classification technique similar to linear regression, but used for binary classification problems. It demonstrates how to fabricate test data using Scikit-learn's make_blobs function, visualize it with Matplotlib, and train a logistic regression model. The tutorial also explains how to evaluate the model's performance using train-test split and cross-validation, achieving an accuracy of 84.2%. The video emphasizes the importance of model evaluation to prevent overfitting and highlights logistic regression as a useful tool for linear relationships in data.
