When the term Artificial Intelligence (AI) is mentioned, most of us immediately think of the self-aware machines depicted within our favorite books or movies.
We imagine robots that can think for themselves such as R2-D2, machines that fight crime and defend humans like Astroboy; or we envision a world in which these thinking machines have turned against us, where the HAL 9000 attacks its crew or Skynet launches an offensive against all mankind.
Whether we see AI as good or bad, many of us see AI as an inevitable progression of computer science, where computer systems are ultimately able to think and problem solve as well or better than humans do.
The reality of modern AI is both less glamorous and more fascinating.
Artificial intelligence is being used in an increasing number of ways, from providing online help to interpreting handwriting to driving cars, but none of these quite compare to the Hollywood vision. It is easy to overlook the tremendous advances we have made or the incredible science behind these achievements.
In computer science, AI programming involves designing systems that can "rationalize" a problem, evaluating multiple possible outcomes and selecting a path with the highest potential for success.
Once an AI program chooses its solution, it should then be able to evaluate the results of that action, and refer back to that information the next time it has to make a similar decision. In this way, an AI system "learns" and "problem-solves" within the bounds of its programming.
Unlike traditional programming, which relies primarily on math and logic, AI programming requires computer scientists to incorporate a variety of other disciplines, such as psychology, neuroscience, and linguistics, in order to develop systems that can replicate human-like thought processes and behaviors.
AI research tends to focus on specific areas of intelligence, such as reasoning, planning, communication, creativity, and object manipulation. For many, this is where AI falls short of our expectations.
Rather than acting like fully-functioning humans, AI programs typically have a very narrow focus, such as learning to play a specific game or providing logical responses to typed or asked questions.
But these accomplishments should not be overlooked, as each small advancement tasks takes AI one-step closer to the ultimate goal of General Intelligence.
History of AI Programming
While stories have been created and theories proposed about the possibility of AI for centuries, there was little formalized study of AI until the 1956 Dartmouth Summer Research Project on Artificial Intelligence established AI as a legitimate field of research.
For the next fifteen years, AI research took several major leaps forward, during which time computers were taught to win at checkers, solve advanced math problems, and even speak.
When government funding dried up in the mid-1970s, AI research slowed for several years. But during the 1980s our interest in AI was revitalized, largely based on the success of expert systems, mainframe computers designed for decision making tasks.
These expert machines utilized a knowledge base of rules and known facts along with an inference engine in order to apply pre-existing knowledge to infer new fact.
At the same time, the rise of the PC created a whole new arena for AI research.
The client-server model allowed programmers the freedom to forego the massive mainframes — a considerable savings in terms of time and budget.
And as computers become more interconnected throughout the 1980s and 1990s, AI researchers were able to take advantage of the power of shared computing environments.
During this entire period, the field of AI was expanding and gaining notoriety. One of the most recognizable developments occurred in 1997, when IBM's Deep Blue defeated the reigning world chess champion, Garry Kasparov.
This event marked a significant turning point for AI, as it demonstrated that a computer could not only learn a game but could achieve a level of mastery previously thought only available to humans.
Today, the field of AI has seen many real-world applications from computerized personal assistance on our smartphones to self-driving cars, and the demand for further automation is on the rise.
While general intelligence may still be reserved for sci-fi films, computers are able to tackle more complex decision-making processes every day.
