Overview
The exam tests supervised learning, the foundation for many machine learning applications. Supervised learning involves training models on labeled data – data where the correct output is already known. The goal is for the model to learn the relationship between the input features and the output, enabling it to predict outcomes for new, unseen data.
Core Concepts
- **Regression vs. Classification:** Regression predicts continuous values; classification predicts discrete categories. Recognize the difference based on the problem you're trying to solve.
- **Feature Scaling:** Techniques like Min-Max scaling and Z-score normalization transform features to a similar scale. This is vital for algorithms sensitive to feature ranges, like gradient descent and distance-based methods.
- **Gradient Descent:** An iterative optimization algorithm used to minimize cost functions. Understanding the learning rate and its impact on convergence is key. A learning rate that is too large can cause divergence.
Exam Tips
- Carefully read the problem description to determine whether it requires regression or classification.
- Pay close attention to the ranges of features and the potential impact of outliers when choosing a feature scaling method.
