Due to difficulties in converging the two-level model, we tested the differences between one- and two-level models and found that the variances between GPs were small, and differences in PR estimates were therefore negligible (below 2%).
However, k-means algorithm had difficulty to converge on the same cluster assignments for 69 vectors.
When using the concentration-error minimization, simultaneous optimization met great difficulty to converge due to stiff ODE integrations.
Last week, I asked Mark Fitzpatrick, senior fellow for nonproliferation at the International Institute for Strategic Studies here, and a former State Department expert on nuclear issues, about where he saw the difficulties converging next year.
First, despite the difficulty in proving the convergence of full IFEM algorithms, both IFEM-1 and IFEM-2 are always observed to converge.
This is a very challenging problem and often inexact Newton solvers present severe difficulties to converge.
In contrast, converging evidence showed that task difficulty (i.e., the complexity of the cognitive process) could activate a set of typically cognitive subdivisions, including the dorsolateral prefrontal cortex, dorsal anterior cingulated cortex, and parietal cortex [37] [40].
Some in Europe and America are converging in the direction of protectionism.
Regardless of its cause, running so many platforms failing to converge on a single enterprise solution adds to the difficulty in training, leads to confusion and, in general, greatly reduces adoption rates.
Difficulty in keeping hatband exclusive.
