Abstract Early cost estimation of machined parts is difficult as it requires detailed process information that not usually available during product design. Parametric methods address this issue by estimating machining time from predictors related to design choices. One them complexity, defined a function dimensions and tolerances an analogy with theory. However, complexity has only limited corr...

Abstract In order to effectively mine the structural features in time series and simplify complexity of analysis, equiprobable symbolization pattern entropy (EPSPE) is proposed this paper. The original are implemented through symbolic processing according an equal probability distribution. Then, sliding window technique used obtain a finite number different patterns, pairs determined by calcula...
