Study Notes
Supervised Learning: Overview
- Supervised learning is a type of machine learning that uses labeled data to train machine learning models.
- Labels are provided, and the model maps inputs to respective outputs.
- Supervised learning algorithm works by analyzing labeled training data and produces/builds a function/model that predicts target outputs for new examples.
Supervised Learning: Examples
- Example 1: A supervised machine learning algorithm is used to identify patients as "healthy" or "sick" based on their age and gender parameters.
- Example 2: A supervised learning algorithm is used to train a system that identifies images of animals.
Supervised Learning: Why "Supervised Learning"?
- Supervised learning methods need external supervision to train machine learning models.
- The algorithm is guided by a teacher that corrects its predictions until it achieves an acceptable level of performance.
Supervised Learning: Types of Problems
- Classification and regression problems are the most common types of supervised learning problems.
Supervised Learning: Classification
- Classification: predicting categorical labels.
- Works by pattern recognition.
- Examples: face recognition, optical character recognition, credit scoring.
Supervised Learning: Regression
- Regression: predicting continuous labels.
- Examples: predicting the price of a car from its mileage, credit scoring.
Supervised Learning: Algorithms
- A wide range of supervised learning algorithms are available, each with its strengths and weaknesses.
- Popular algorithms include Linear Regression, Logistic Regression, Support Vector Machine, K Nearest Neighbor, Decision Tree, Random Forest, and Naive Bayes.
Supervised Learning: Applications
- Supervised learning algorithms are used for classification and regression problems.
- Applications include weather prediction, sales forecasting, and stock price analysis.
Unsupervised Learning
- Unsupervised learning is a type of machine learning that uses unlabeled data.
