Empirical Laws and Foreseeing the Future of Technological Progress

Abstract: The Moore's law (ML) is one of many empirical expressions that is used to characterize natural and artificial phenomena. The ML addresses technological progress and is expected to predict future trends. Yet, the "art" of predicting is often confused with the accurate fitting of trendlines to past events. Presently, data-series of multiple sources are available for scientific and computational processing. The data can be described by means of mathematical expressions that, in some cases, follow simple expressio… Show more

“…In the case of the DJIA, two data pre-processing schemes (also called normalizing, or data transformation), and , are considered: (i) subtracting the arithmetic average and dividing by the standard variation, that is by calculating , where and , and (ii) by applying a logarithm so that . The linear transformation is often adopted in statistics and signal processing [ 64 , 65 , 66 , 67 , 68 ], while the non-linear transformation can be adopted with signals revealing an exponential-like evolution [ 69 , 70 , 71 , 72 , 73 ]. Of course, other data transformations could be envisaged, but these two are commonly adopted.…”

“…We can adopt other fitting models, eventually with more parameters, that adjust better to some particular series x i (k). However, only simple analytical expressions, requiring a limited set of parameters, are considered [31], otherwise the interpretation of the parameters becomes unclear. Moreover, loosely speaking, with exception of Qu, these heuristic models reflect somehow fractional characteristics, embodied in their structures by the non-integer exponents.…”

“…Sigmoidal models have been shown to be compatible with technological evolution, even in the context of Moore’s Law of transistor performance [ 6 – 8 ], giving rise to decreasing growth rates as a technology matures. S-curves can describe the growth of technological performance [ 9 11 ].…”
