WebSep 27, 2024 · Here, we consider majority rule dynamics on organisations modelled as hierarchical directed graphs, where the directed edges indicate influence. We utilise a topological measure called the trophic incoherence parameter, q, which effectively gauges the stratification of power structure in an organisation. Webincoherence parameter. (For a technical description of these measures, see Methods.) Significance The fact that large, complex ecosystems are particularly robust is mysterious in the light of mathematical arguments that suggest they should be unstable; i.e., susceptible to runaway fluctuations in species’ abundances. Here we show that food

WebHere C is a numerical constant that only depends on the condition number of X* and on its incoherence parameter. Its time complexity is only Cmqnr log 2 (1/∈). Since even the linear (with phase) version of the above problem is not fully solved, the above result is also the first complete solution and guarantee for the linear case. Web2. I am having two different definitions of matrix coherence. Wikipedia (and its assorted references) defines it as follows: "the coherence or mutual coherence of a matrix A is defined as the maximum absolute value of the cross-correlations between the columns of A." However, there are machine learning paper (s) that define it as "Matrix ... WebThen the incoherence parameter (X(L)) defined in [22] is at least cos(ˇ=6). However under our new definition, it is not difficult to show that (X(L)) 2 q 6log(L) n with high probability 3. The result also depends on the smallest singular value of a rank-dmatrix (denoted by ˙ d) and the inradius of a convex body as defined below. cityfitnessworld.com
