Abstract. Given an undirected graph G, the classical Cheeger constant, hG, measures the optimal partition of the vertices into 2 parts with relatively few edges between them based upon the sizes of the parts. The wellknown Cheeger’s inequality states that 2λ1 ≤ hG ≤ √ 2λ1 where λ1 is the minimum nontrivial eigenvalue of the normalized Laplacian matrix. Recent work has generalized the concept of...

Cross-validation type of methods have been widely used to facilitate model estimation and variable selection. In this work, we suggest a new K-fold cross validation procedure to select a candidate 'optimal' model from each hold-out fold and average the K candidate 'optimal' models to obtain the ultimate model. Due to the averaging effect, the variance of the proposed estimates can be significan...

A k-fold x-coloring of a graph G is an assignment of (at least) k distinct colors from the set {1, 2, . . . , x} to each vertex such that any two adjacent vertices are assigned disjoint sets of colors. The k-th chromatic number of G, denoted by χk(G), is the smallest x such that G admits a k-fold x-coloring. We present an ILP formulation to determine χk(G) and study the facial structure of the ...

The known O(dk log k) bound on the VC dimension of k-fold unions or intersections of a given concept class with VC dimension d is shown to be asymptotically tight.

The numerical value of k in a k-fold cross-validation training technique machine learning predictive models is an essential element that impacts the model’s performance. A right choice results better accuracy, while poorly chosen for might affect In literature, most commonly used values are five (5) or ten (10), as these two believed to give test error rate estimates suffer neither from extreme...
