Detection of a signal in linear subspace with bounded mismatch [PDF]

open access: yes, 2006
We consider the problem of detecting a signal of interest in a background of noise with unknown covariance matrix, taking into account a possible mismatch between the actual steering vector and the presumed one.

SIGNAL PROBABILITY, REINFORCEMENT AND SIGNAL DETECTION [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1979
Five pigeons were trained to detect differences in light intensity. Two stimuli, S1 and S2, differing in intensity, were arranged on the center key of a three‐key chamber according to set probabilities. A peck on the center key turned on the two side keys.
