We propose the weighted optimality criterion using the geometric mean as the objective function for the genetic algorithms. We generate a robust mixture design using genetic algorithms (GAs) of which the region of interest is an irregularly shaped polyhedral region formed by constraints on proportions...
If provided an input value x, the accumulator function returns an updated geometric mean. If not provided an input value x, the accumulator function returns the current geometric-mean. var accumulator = incrmgmean( 3 ); var v = accumulator(); // returns null // Fill the window... v =...
torch.scatter_reduce(torch.zeros(2), dim=0, index=idx, src=x, reduce="mean") gives: >>> tensor([-0.5841, 0.4428]) However, this is not what one would get by taking the mean of[-1.7451, -1.6061, 1.0150]and[0.8855]respectively: x[:3].mean(), x[3:].mean() >>> (tensor(-0....
Geometric meanHarmonic meanPower meanSubstitutive meanScholars often consider the arithmetic mean as the only mean available. This gives rise to several mistakes. Thus, in a first course in statistics, it is necessary to introduce them to a more general concept of mean. In this work we ...

I had to make some assumptions about how to measure "yellowness"; I decided to use the geometric mean of red and green, sqrt(R*G). Possibly min(R,G) would be a better measure, but one more difficult to work with analytically. For black versus white, I used the typical luminance, ...
In this paper, I will be employing a pseudo-geometric series approach to derive a new formula for calculating which includes other equally fascinating mathematical constants √2, golden ratio, silver ratio and Euler's Constant in an infinite series. By pseudo-geometric, I mean that the tools em...
