History of AI
- 27. Types of Artificial Intelligence: • Artificial Intelligence can be divided in various types, there are mainly two types of main categorization which are based on capabilities and based on functionally of AI. • Following is flow diagram which explain the types of AI
- 28. AI type-1: Based on Capabilities 1. Weak AI or Narrow AI: • Narrow AI is a type of AI which is able to perform a dedicated task with intelligence. • The most common and currently available AI is Narrow AI in the world of Artificial Intelligence. • Narrow AI cannot perform beyond its field or limitations, as it is only trained for one specific task. Hence it is also termed as weak AI. • Narrow AI can fail in unpredictable ways if it goes beyond its limits. • Apple Siri is a good example of Narrow AI, but it operates with a limited pre-defined range of functions. • IBM's Watson supercomputer also comes under Narrow AI, as it uses an Expert system approach combined with Machine learning and natural language processing. • Some Examples of Narrow AI are playing chess, purchasing suggestions on e-commerce site, self-driving cars, speech recognition, and image recognition.
- 29. 2. General AI: • General AI is a type of intelligence which could perform any intellectual task with efficiency like a human. • The idea behind the general AI to make such a system which could be smarter and think like a human by its own. • Currently, there is no such system exist which could come under general AI and can perform any task as perfect as a human. • The worldwide researchers are now focused on developing machines with General AI. • As systems with general AI are still under research, and it will take lots of efforts and time to develop such systems.
- 30. 3. Super AI: • Super AI is a level of Intelligence of Systems at which machines could surpass human intelligence, and can perform any task better than human with cognitive properties. • It is an outcome of general AI. • Some key characteristics of strong AI include capability include the ability to think, to reason, solve the puzzle, make judgments, plan, learn, and communicate by its own. • Super AI is still a hypothetical concept of Artificial Intelligence. • Development of such systems in real is still world changing task.
- 31. Artificial Intelligence type-2: Based on functionality 1. Reactive Machines • Purely reactive machines are the most basic types of Artificial Intelligence. • Such AI systems do not store memories or past experiences for future actions. • These machines only focus on current scenarios and react on it as per possible best action. • IBM's Deep Blue system is an example of reactive machines. • Google's AlphaGo is also an example of reactive machines. 2. Limited Memory • Limited memory machines can store past experiences or some data for a short period of time. • These machines can use stored data for a limited time period only. • Self-driving cars are one of the best examples of Limited Memory systems. • These cars can store recent speed of nearby cars, the distance of other cars, speed limit, and other information to navigate the road.
- 32. 3. Theory of Mind • Theory of Mind AI should understand the human emotions, people, beliefs, and be able to interact socially like humans. • This type of AI machines are still not developed, but researchers are making lots of efforts and improvement for developing such AI machines. 4. Self-Awareness • Self-awareness AI is the future of Artificial Intelligence. • These machines will be super intelligent, and will have their own consciousness, sentiments, and self-awareness. • These machines will be smarter than human mind. • Self-Awareness AI does not exist in reality still and it is a hypothetical concept.
- 34. The state of the ART: What can AI do today? A concise answer is difficult because there are so many activities in so many subfields. Robotic vehicles: A driverless robotic car named STANLEY sped through the rough terrain of the Mojave dessert at 22 mph, finishing the 132-mile course first to win the 2005 DARPA Grand Challenge. Speech recognition: A traveler calling United Airlines to book a flight can have the entire conversation guided by an automated speech recognition and dialog management system. Autonomous planning and scheduling: A hundred million miles from Earth, NASA’s Remote Agent program became the first on-board autonomous planning program to control the scheduling of operations for a spacecraft (Jonsson et al., 2000). Game playing: IBM’s DEEP BLUE became the first computer program to defeat the world champion in a chess match when it bested Garry Kasparov by a score of 3.5 to 2.5 in an exhibition match (Goodman and Keene, 1997)
- 35. • Spam fighting: Each day, learning algorithms classify over a billion messages as spam, saving the recipient from having to waste time deleting what, for many users, could comprise 80% or 90% of all messages, if not classified away by algorithms. • Logistics planning: During the Persian Gulf crisis of 1991, U.S. forces deployed a Dynamic Analysis and Replanning Tool, DART (Cross and Walker, 1994), to do automated logistics planning and scheduling for transportation. 🡪This involved up to 50,000 vehicles, cargo, and people at a time, and had to account for starting points, destinations, routes, and conflict resolution among all parameters. • Robotics: The iRobot Corporation has sold over two million Roomba robotic vacuum cleaners for home use. • Machine Translation: A computer program automatically translates from Arabic to English, allowing an English speaker to see the headline “Ardogan Confirms That Turkey Would Not Accept Any Pressure, Urging Them to Recognize Cyprus.”
