The genotype distance between a brown hen and a white hen is relatively large such that the kernel value of those two genotypes by Equation (10) becomes small.
The distance can be divided into two parts: (2) If we change x, then k x,x i) = ϕ(x)· ϕ(x i) changes, which is the kernel value of x and x i.
Together, they generate all the multiplier values corresponding to all the kernel values of the considered transforms.

Intuitively, a k-spectrum kernel [24] captures a simple notion of string similarity: two strings are deemed similar (i.e., have a high k-spectrum kernel value) if they share many of the same k-mer substrings.
Thus, the latter can be obtained using the identity of the kernel value for an object pair (x, y) ∈ X × X and the inner product of the respective feature space projection φ (x) for x ∈ X: (5).
Second, to test if the curvilinear specification was accurately capturing the slope directions from negative to zero and zero to positive, we replaced the continuous and quadratic food environment terms with a piecewise linear spline with a knot at the kernel density value of zero.
Indeed, as mentioned before for the shrinking of the viability kernel, a high value of a means that agents rarely change their language and the effects of increasing or decreasing the prestige of a language become less effective.
The overlaying of kernel values over the median of WNV and USUV, produce two areas of strong simultaneous circulation of both viruses, whose centroids are approximately 20 km distant: one in Bologna province (6650 ha) and one in Ferrara province (5456 ha) (Figure 3).
The basic idea is to substitute the inner product in the high-dimensional space by the kernel function value of the input vectors to avoid complex calculation procedures of the high-dimensional vectors, i.e., the kernel trick.
