Study Notes
Machine Learning Terminology
- Features are unique characteristics or details that help identify or describe something, such as a car's color, model, and year.
- A sample is a single piece of data used to study or learn from, like a photo, sound clip, or spreadsheet row.
- A feature vector is a list of feature values representing an object, such as a car's feature vector being ["Red", "Toyota", "2015"].
- Feature extraction is the process of simplifying or transforming data to make it easier to work with, like reducing an image's resolution.
Machine Learning Concepts
- Learning is the process where a machine learning model improves its predictions based on feedback.
- Intelligence is the ability to make correct decisions or predictions, such as diagnosing a disease based on symptoms.
- Artificial Intelligence is when a computer is programmed to make intelligent decisions, like diagnosing diseases.
Importance of Machine Learning
- Machine learning is useful in situations where it's hard for humans to explicitly program correct behavior or when the correct behavior might change over time.
- Examples include programming a car to drive or a spam filter to identify spam emails.
Machine Learning Process
- The learning system model involves a training set, predictions, and updates based on performance.
- Training and testing involve using a training set to teach a model and a testing set to evaluate its performance.
Types of Machine Learning
- Machine learning is a field of Artificial Intelligence that tries to make computers learn from data.
- Learning means improving at a task based on experience, such as a spam filter learning to identify spam emails.
- Types of learning include:
- Rote learning: simple memorization
- Learning from instruction: being told what to do
- Learning by analogy: applying learned concepts to new contexts
- Learning from observation and discovery (unsupervised learning): learning from data without explicit instructions
- Learning from examples (inductive learning): learning from specific examples and generalizing to new situations
Inductive and Deductive Learning
- Inductive learning involves learning general rules from specific examples.
- Deductive learning involves using known facts and rules to learn new rules.
