The primary objective of this paper is to classify the operator functional states (OFS) in the control of human-machine system. In a lab environment, 11 subjects were employed to simulate a set of process control tasks in an automated cabin air management system (aCAMS), recording psychophysiological signal and performance appearance. The fuzzy C means classification algorithm is used to classify...
Aiming at multi-classification and multi-label in text categorization, an apery algorithm is proposed which judges whether document has multi-classification and multi-label by estimating the similarity difference among final classifier values. If the quotient of the biggest category's classifier value divided by the second biggest category's classifier value is less than or equal to a threshold, the...
Key words are expressions that indicate and express the subject concept of a text, the major property of key words is to denote subject. Based on the domainal inhomogeneity and critical region of key words, subject degree is brought up and calculated by statistical model to cue textpsila subject concept. Based on key words and itspsila subject degree, constructed a comprehensive auto-indexing system,...
