Let $G$ be a finite group and $pi_{e}(G)$ be the set of orders of all elements in $G$. The set $pi_{e}(G)$ determines the prime graph (or Grunberg-Kegel graph) $Gamma(G)$ whose vertex set is $pi(G)$, the set of primes dividing the order of $G$, and two vertices $p$ and $q$ are adjacent if and only if $pqinpi_{e}(G)$. The degree $deg(p)$ of a vertex $pin pi(G)$, is the number of edges incident...

Although K-fold cross-validation (CV) is widely used for model evaluation and selection, there has been limited understanding of how to perform CV non-iid data, including those from sampling designs with unequal selection probabilities. We introduce methodology that appropriate design-based inference complex survey designs. For such we claim will tend make better inferences when choose the fold...

We present some applications of the deformation theory toric Fano varieties to K-(semi/poly)stability varieties. First, we two examples K-polystable 3-fold with obstructed deformations. In one case, K-moduli spaces and stacks are reducible near closed point associated 3-fold, while in other they non-reduced 3-fold. Second, study K-stability general members families smooth 3-folds by building de...

abstract in this presentation, a case of bilateral choroidal folds in patient with diabetic retinopathy was reported. by our knowledge, this case presentation is the first report of choroidal folds in diabetic retinopathy, which bilateral symmetric and horizontal folds arranged in macula. the thick choroid that is developed in diabetics may be a cause of these folds but the source of difference...

This study analyzes the performance of k-Nearest Neighbor method with k-Fold Cross Validation algorithm as an evaluation model and Analytic Hierarchy Process feature selection for data classification process in order to obtain best level accuracy machine learning model. The test results are fold-3, which is getting rate 95%. Evaluation can get a good also gets optimal reduce because it only use...
