Artificial Intelligence Flashcards
what is AL?
it considers all aspects of intelligence and models these using computer systems. the aim is to create intelligent machines which can function like humans by learning and adapting
what is turing test?
its a test to determine a machines behaviour is indistinguishable from human’s response. the test involves a player, human and machine. the player does not know which is the human and computer. the player asks questions of the human and the machine tries to discover which is human
what are the main features of a neural network?
a netural network models athe human brain. it consists of a cllection of nodes linked by one-way connections. each node calculates the weighted sum of its inputs and provides an output. backward popagation may be used
what is a netural network?
its deisgned to stimulate lots of density interconnected brain cells to support learning, pattern recognition and the decision making process in the same way a human being would
how does netural network learn?
patterns of information flowing into netural network will enter the network via the input units, triggering layers of hidden units until they arrive at the output units
what is feedforward network?
the weighted inputs are added together and if the sum is above a given threshold vlue that unit will fire the units connected to it
what is the aim of backpropagation?
it reduces the difference between the actual and tended output, causing learning to occur
