Study Notes
Machine Learning Introduction
- Machine learning is programming computers to optimize a performance criterion using example data or past experience.
- It is used when human expertise does not exist, when humans are unable to explain their expertise, when the solution changes over time, or when the solution needs to be adapted to particular cases.
Types of Machine Learning
-
Supervised Learning: Uses labeled data to learn a mapping between input and output variables, with the goal of making predictions on new, unseen data.
- Examples: Image classification, speech recognition, credit scoring
- Applications: Biometrics, face recognition, signature verification
-
Unsupervised Learning: Finds patterns or structure in unlabeled data, with no target output.
- Examples: Customer segmentation, image compression, bioinformatics
- Applications: Market basket analysis, customer relationship management (CRM), anomaly detection
-
Reinforcement Learning: Learns a policy through trial and error, with a delayed reward signal.
- Examples: Game playing, robot navigation, autonomous vehicles
- Applications: Robotics, game playing, recommendation systems
Machine Learning Applications
-
Classification: Predicting a categorical label or class.
- Examples: Credit scoring, medical diagnosis, speech recognition
- Applications: Pattern recognition, face recognition, character recognition
-
Regression: Predicting a continuous value or range.
- Examples: Predicting the price of a used car, kinematics of a robot arm
- Applications: Predicting continuous outcomes, optimization problems
-
Regression Types
- Univariate Regression: One input feature.
- Multivariate Regression: Multiple input features.
- Time Series Prediction: Predicting future values in a sequence.
Big Data and Learning
- Big Data: The widespread use of personal computers and wireless communication has led to an explosion of data.
- Machine Learning is Needed: To extract structure from data, understand processes, and make predictions for the future.
Biometrics and Face Recognition
- Biometrics: Recognition and authentication using physical and/or behavioral characteristics, such as face, iris, signature, etc.
- Face Recognition: Uses training examples of a person to recognize them in test images, with applications in security and authentication.
