ARTIFICIAL INTELLIGENT


           The modern definition of artificial intelligence (or AI) is "the study and design of intelligent agents" where an intelligent agent is a system that perceives its environment and takes actions which maximizes its chances of success.
John McCarthy, who coined the term in 1956, defines it as "the science and engineering of making intelligent machines."
Other names for the field have been proposed, such as computational intelligence, synthetic intelligence or computational rationality.
The term artificial intelligence is also used to describe a property of machines or programs: the intelligence that the system demonstrates.
AI research uses tools and insights from many fields, including computer science, psychology, philosophy, neuroscience, cognitive science, linguistics, operations research, economics, control theory, probability, optimization and logic.
AI research also overlaps with tasks such as robotics, control systems, scheduling, data mining, logistics, speech recognition, facial recognition and many others.
Computational intelligence Computational intelligence involves iterative development or learning (e.g., parameter tuning in connectionist systems).
Learning is based on empirical data and is associated with non-symbolic AI, scruffy AI and soft computing.
Subjects in computational intelligence as defined by IEEE Computational Intelligence Society mainly include: Neural networks: trainable systems with very strong pattern recognition capabilities.
Fuzzy systems: techniques for reasoning under uncertainty, have been widely used in modern industrial and consumer product control systems; capable of working with concepts such as 'hot', 'cold', 'warm' and 'boiling'.
Evolutionary computation: applies biologically inspired concepts such as populations, mutation and survival of the fittest to generate increasingly better solutions to the problem.




These methods most notably divide into evolutionary algorithms (e.g., genetic algorithms) and swarm intelligence (e.g., ant algorithms).
With hybrid intelligent systems, attempts are made to combine these two groups.
Expert inference rules can be generated through neural network or production rules from statistical learning such as in ACT-R or CLARION.
It is thought that the human brain uses multiple techniques to both formulate and cross-check results.
Thus, systems integration is seen as promising and perhaps necessary for true AI, especially the integration of symbolic and connectionist models.

This is what 24 of the world's most iconic flags mean

F rom the skull and bones at the top of a pirate ship to a white flag on a battlefield, a single piece of fabric can be interpreted in a multitude of ways. Depending on where they fly, flags can represent freedom or control, danger or safety. In the context of modern times, flags are best known as national symbols — and they’re used to air a country’s past, present, and future vision all rolled into one. The Meaning of Flags Today’s infographic from Just the Flight looks at some the world’s most iconic flags, and the intricate stories and ideals that can be found in their designs. The Americas Since 1777, the star-spangled banner of the United States has gone through several facelifts. The current version has been in use since Hawaii gained statehood in 1960. Puerto Rico has been voting to become the 51st state in recent years — and if the U.S. government proved to accept such a resolution, the flag would be amended onc...

Scientists break record for highest-temperature superconductor

University of Chicago scientists are part of an international research team that has discovered superconductivity -- the ability to conduct electricity perfectly -- at the highest temperatures ever recorded. Using advanced technology at UChicago-affiliated Argonne National Laboratory, the team studied a class of materials in which they observed superconductivity at temperatures of about minus-23 degrees Celsius (minus-9 degrees Fahrenheit) -- a jump of about 50 degrees compared to the previous confirmed record. Though the superconductivity happened under extremely high pressure, the result still represents a big step toward creating superconductivity at room temperature -- the ultimate goal for scientists to be able to use this phenomenon for advanced technologies. The results were published May 23 in the journal  Nature ; Vitali Prakapenka, a research professor at the University of Chicago, and Eran Greenberg, a postdoctoral scholar at the University of Chicago, are co-au...
