Learning Systems

• Another way to get the knowledge is to use an AI program that automatically learns the knowledge.
• A neural net is a system that can be used to automatically learn knowledge.
• Feed forward nets learn functions from inputs to outputs by training on existing data.
• There are also symbolic knowledge acquisition systems. This is called machine learning.
• Machine learning can be used when there are no experts, or expertise is expensive.
• This machine learning is almost the same thing as data mining.
• Currently, an expert is better in almost all things than a machine learning system.
