Digital signals, features construction, optimization algorithms


Two ways of efficient features construction for linear local description of one-dimension signal are considered in the work. These approaches use global optimization algorithms for determination of feature parameters. The comparison of these ways is performed as well as the comparison with the way which uses pseudogradient algorithm. The quality criterion used for comparison is the value which describes cumulatively the correlation degree of sequences that define impulse responses of features computation algorithm and the precision of representation of given signals set with the help of this sequences.
