Write Program to Plan AI - In the very beginning, artificial intelligence  used something called the symbolic systems approach.  This approach allowed machines to act in a way  that seemed intelligent,  but in reality it was just complex pattern matching.  The symbolic systems approach allowed early programmers  to create expert systems.  These machines could do things  that were normally left to experts.  They could diagnose illnesses, give you a credit score,  and even help you with your taxes. The problem with these systems is that they  created long lists of matching patterns. Plan AI  They also required experts to create these patterns.  You needed someone who knew Chinese  to match every possible phrase.  Maybe you'd need a doctor who would  come up with an answer  to every one of a patient's questions.  You had to create these long lists of matching patterns. Sometimes this is ca...

Strong vs. weak AI - The philosopher John Searle pointed out  that you can think of artificial intelligence  in two different ways.  There's strong AI, and weak AI.  Strong AI is when you have a machine  that displays all the behavior  that you'd expect from a full fledged artificial person.  This is usually what you see in science fiction movies.  These are artificial beings that have emotions,  a sense of purpose and can even tell jokes.  Some computer scientists also refer to strong AI  as general artificial intelligence.  General AI is a broad intelligence  that doesn't just apply to one narrow task. Strong vs. weak AI Think of it this way, a strong AI machine  might learn a new language just for the joy  of learning a new language.  On the flip side, there's weak AI,  often called narrow AI.  This is AI that is confined to a very narrow task.  It might be like trying to process  your...

Define general intelligence : Smart Patterns  - Back in 1955, Dartmouth Professor John McCarthy  coined the term artificial intelligence.  He created the term as part of an academic grant  to fund the first AI workshop.  This workshop was to see if early computers  could behave in ways that everyday people  would identify as intelligent.  In the early 1950s, single computers  were taking up entire floors.  Even with their enormous size,  they had much less processing power  than modern smartphones. Define general intelligence So they didn't make much progress  creating a fully intelligent artificial person.  What they did do was create a new term  that ignited everyone's imagination.  The term, artificial intelligence, inspired a new generation  of journalists, writers, academics, and computer scientists.  It opened the door to large grants  that early computer scientists  used to build o...
