Nonnegative matrix factorization (NMF) approximates a given data matrix using linear combinations of a small number of nonnegative basis vectors, weighted by nonnegative encoding coefficients.
On the other hand, BEM describes the doubly selective channel as the superpositions of time-varying basis functions weighted by time-invariant coefficients.
Elemental forms of Mg (Sigma Aldrich, ≥ 99%), Sc (Sigma Aldrich, 99.9%), or Y (Goodfellow, 99.9%), and Se (Sigma Aldrich 99.99% trace metal basis) are first weighted with the stoichiometric ratio.
Lipton said that after recent changes in global exchange rates, "We believe that it is no longer undervalued". That's on a trade weighted basis of course: that's how these things are worked out.
In addition, the patterns learned by the classifier are used as a basis for performing weighted clustering.
Since the data was collected on a per horizon basis, the weighted average of the SOC content of the different horizons was used to calculate the proportion of SOC in the first 30 cm.
In recent applications of MCDA [ 15- 19], it has been criticized for its quantitative nature - studies typically rank ordered interventions on the basis of weighted averages and, in this way, consider quantifiable criteria only.
In line with the study environment and with reference to other similar studies [ 1, 27], the socioeconomic status of each household was assessed using an index calculated on the basis of weighted categories (Table 1).
Hence, multiple surrogates such as response surface approximation, radial basis function, Kriging and weighted average surrogates were incorporated in this problem.
In every biannual report since its inception, the average actively managed fund has underperformed a comparable index in most categories on an equal-weighted basis and on an asset-weighted basis.
