What is Learning? How can Learning be measured?
Any change in the knowledge of a system that allows it to perform better on subsequent tasks.
Knowledge. How should knowledge be represented? Does anybody know how it is represented in the human brain?
Think for a moment about how knowledge might be represented in a computer.
If I told you what subjects would come up in the exam, you might do very well. Would you do so well if I then set randomly chosen subjects from the syllabus? (This illustrates the notion called ‘overfitting’ - something one should guard against.)
