The processes machines use to learn are known as algorithms. Different algorithms learn in different ways. As new data regarding observed responses or changes to the environment are provided to the “machine” the algorithm's performance improves. Thereby resulting in increasing “intelligence” over time.
Machines learn by studying data to detect patterns or by applying known rules to:
- Categorize or catalog like people or things
- Predict likely outcomes or actions based on identified patterns
- Identify hitherto unknown patterns and relationships
- Detect anomalous or unexpected behaviorsÂ
