Learning From Examples
- Learn general concepts or categories from examples
-
- Learn a task (drive a vehicle, win a game of backgammon)
-
- Examples of objects or tasks are gathered and stored in a database
-
- Each example is described by a set of attributes or features
-
- Each example used for training is classified with its correct label (chair, not chair, horse, not horse, 1 vs. 2 vs. 3, good move, bad move, etc.)
-
- The machine learning program learns general concept description from these specific examples
-
- The ML program should be applied to classify or perform tasks never before seen from learned concept
