Stage 3: Learning Machine Learning Algorithms

Machine learning is at the heart of data science, enabling you to create predictive models and make data-driven decisions. This is the stage where you begin applying algorithms to solve complex problems.

Key Skills to Learn:

1. Supervised Learning

• Regression: Learn techniques such as Linear Regression and Logistic Regression for predicting continuous and categorical outcomes.

• Classification: Understand algorithms like K-Nearest Neighbors (KNN), Decision Trees, Random Forests, and Support Vector Machines (SVM) for classifying data into categories.

2. Unsupervised Learning

• Learn about Clustering algorithms like K-Means and Hierarchical Clustering, which are used to group similar data points together.

• Dimensionality Reduction techniques such as PCA (Principal Component Analysis) help reduce the complexity of large datasets.

3. Model Evaluation and Tuning
   Understand how to evaluate models using metrics like accuracy, precision, recall, F1 score, and ROC-AUC. Learn the importance of hyperparameter tuning and cross-validation to improve model performance.
