Nettet4. mar. 2024 · My goal is to find the best solution with a restricted number of non-zero coefficients, e.g. when I know beforehand, the data contains two Gaussians. So far, I used the grid search over the parameter space of number of features (or their spacing) and the width of the features, as well as the alpha parameter. NettetMathematically, an S-box is a vectorial Boolean function. [1] In general, an S-box takes some number of input bits, m, and transforms them into some number of output bits, n, where n is not necessarily equal to m. [2] An m × n S-box can be implemented as a lookup table with 2 m words of n bits each. Fixed tables are normally used, as in the ...
