The sign of g ( x ) can be evaluated by a threshold element whose threshold value is equal to zero . For this reason the threshold element assumes an important role in pattern - classifying machines . We shall use the block diagram of ...

2.6 The threshold logic unit ( TLU ) If R = 2 , a linear machine employs a single linear discriminant function g ( x ) defined by g ( x ) = W1X1 + W2X2 + .. + WaXd + W2 + 1 ( 2:11 ) If g ( x ) > 0,20 = 1 ; if g ( x ) < 0,10 = 2.

The threshold o is chosen to be any convenient negative number if the image - space zero vector is a vertex belonging to I ( 1 ) ; otherwise is chosen to be any convenient positive number . In this way all the pattern vectors which map ...

Tietoja kirjailijasta (1965)

Nils John Nilsson was born in Saginaw, Michigan on February 6, 1933. He received a bachelor's degree and a Ph.D. in electrical engineering from Stanford University. He joined the Air Force and served three years at the Rome Air Development Center before joining the Stanford Research Institute in 1961. He helped develop the first general-purpose robot and was a co-inventor of algorithms that made it possible for the machine to move about efficiently and perform simple tasks. He later worked on the "Computer-based Consultant," which focused on natural language understanding. He wrote several books including Learning Machines: Foundations of Trainable Pattern-Classifying Systems and The Quest for Artificial Intelligence: A History of Ideas and Achievements. He died on April 21, 2019 at the age of 86.
