concept intelligent algorithm in category machine learning

This is an excerpt from Manning's book Algorithms of the Intelligent Web, Second Edition.
Intelligent algorithms are very good at learning a specific concept given relevant data, but they’re poor at learning new concepts outside their initial programming. Consequently, intelligent algorithms or solutions must be carefully constructed and combined to provide a satisfactory experience.
If you recall, we used the phrase intelligent algorithm to describe any algorithm that can use data to modify its behavior. We use this very broad term in this book to encompass all aspects of intelligence and learning. If you were to look to the literature, you’d more likely see several other terms, all of which share a degree of overlap with each other: machine learning (ML), predictive analytics (PA), and artificial intelligence (AI). Figure 1.4 shows the relationship among these fields.
