ABSTRACT
In simulations that are frequently used for examining/describing physical characteristics and are usually time-consuming since there is a large variety of possible input combinations, the appropriate input values are often uncertain and making accurate predictions of system behaviour requires that this uncertainty be propagated to the model's output. When no details on the functional behaviour of the response parameters are available, it is important to be able to obtain information that accurately represents the entire design space. Therefore, design points should be "evenly spread" over the entire region, that is, the design should be space-filling. In this work, we consider Latin Hypercube Sampling and focus on Binning Optimal Symmetric designs which guarantee the space-filling property. We show that the appropriate selection of design points is connected to coding theory, in particular to the selection of appropriate cosets of a Hadamard code, propose techniques to optimally and with low complexity select the best Hadamard cosets, and compare with various alternatives sampling techniques.
