WALD-EM: Wald accumulation for locations and durations of eye movements.

Abraham Wald

This paper grew out of a lecture presented at the 54th Session of the International Statistical Institute in Berlin, August 13 20, 2003, Schneeweiss (2003). It intends not only to outline the eventful life of Abraham Wald (1902 1950) in Austria and in the United States but also to present his extensive scientific work. In particular, the two main subjects, where he earned most of his fame, are ...

Biochemistry: Wald and Brown

(P being the pulsation period) could, therefore, assume any value. Moreover, if the disturbing force were periodic, a resonance of the free and forced periods would be immediately established and the amplitude of the oscillation greatly enhanced. Second-order effects, ignored in the present investigation, would thus probably soon become appreciable and could operate to destroy the resonance. Sh...

The Decentralized Wald Problem

Two detectors making independent observations must decide which one of two hypotheses is true. The decisions are coupled through a common cost function. It is shown that the detectors’ optimal decisions are characterized by thresholds which are coupled and whose computation requires the solution of two coupled sets of dynamic programming equations. An approximate computation of the thresholds i...

Towards Machine Wald

The past century has seen a steady increase in the need of estimating and predicting complex systems and making (possibly critical) decisions with limited information. Although computers have made possible the numerical evaluation of sophisticated statistical models, these models are still designed by humans because there is currently no known recipe or algorithm for dividing the design of a st...
