In 1996: computer called deep blue became first machine to beat a reigning world chess champion, garry karparov. Origin dates back to 1985 feng hsiung hsu, thomas. The study of computer systems that attempt to model and apply the intelligence of. What is artificial intelligence? the human mind. Alphago is based on a recently developed deep artificial neural networks (anns) Take inspiration from the human brain (visual system), neural networks are software systems that can train themselves to make sense of the human world. Receive information from other units (like biological neuron through dendrites) Integrate inputs (similar to ipsps and epsps in real neurons) Each unit has a preferred threshold (like excitation for action potential in neurons) If summed signals are greater than the threshold, the unit will pass information forward in the network. Note: all of this is a set of equations (code), not physical objects. Step 2: create many units and many layers and connect them.
