Probabilistic Size-constrained Microclustering
"... Abstract Microclustering refers to clustering models that produce small clusters or, equivalently, to models where the size of the clusters grows sublinearly with the number of samples. We formulate probabilistic microclustering models by assigning a prior distribution on the size of the clusters, ..."

Size-constrained 2-clustering in the plane with
"... Abstract. We present an algorithm for the 2-clustering problem with cluster size constraints in the plane assuming `1-norm, that works in O(n3 logn) time and O(n) space. Such a procedure also solves a full version of the problem, computing the optimal solutions for all possible constraints on cluste ..."

Partitioning Complex Networks via Size-constrained Clustering
- in Proceedings of the 13th International Symposium on Experimental Algorithms (SEA’14), ser. LNCS
, 2014
"... Abstract. The most commonly used method to tackle the graph partitioning problem in practice is the multilevel approach. During a coarsening phase, a mul-tilevel graph partitioning algorithm reduces the graph size by iteratively contract-ing nodes and edges until the graph is small enough to be part ..."

-pecially if the networks have a highly irregular structure. More precisely, our algorithm provides graph coarsening by iteratively contracting size-constrained clusterings that are computed using a label propagation algorithm. The same al-gorithm that provides the size-constrained clusterings can also be used during
Abstract Modifying XCS for Size-Constrained Systems
"... Extended Classifier Systems, or XCS, is a soft-computing approach to machine learning in rule-based systems. While XCS has been shown effective in learning accurate, compact and complete mappings of an environment’s payoff landscape, it can require significant resources to do so. This paper presents ..."

presents four modifications that allow XCS to achieve high performance even in highly size-constrained populations. By modifying the genetic algorithm trigger function, the classifier deletion-selection mechanism, the frequency of classifier parameter updates and the genetic algorithm selection function
A Fast and Elitist Multi-Objective Genetic Algorithm: NSGA-II
, 2000
"... Multi-objective evolutionary algorithms which use non-dominated sorting and sharing have been mainly criticized for their (i) O(MN computational complexity (where M is the number of objectives and N is the population size), (ii) non-elitism approach, and (iii) the need for specifying a sharing param ..."

Tracking Leukocytes In Vivo With Shape And Size Constrained Active Contours
, 2002
"... Inflammatory disease is initiated by leukocytes (white blood cells) rolling along the inner surface Hning of small blood vessels called postcapillary venules. Studying the number and velocity of rolling leukocytes is essential to understanding and successfully treating inflammatory diseases. Potent ..."

method Hes in the energy functional that constrains the shape and size of the active contour. This paper introduces a significant enhancement over existing gradientbased snakes in the form of a modified gradient vector flow. Using the gradient vector flow, we can track leukocytes rolling at high speeds

Fast texture synthesis using tree-structured vector quantization

Figure 1: Our texture generation process takes an example texture patch (left) and a random noise (middle) as input, and modifies this random noise to make it look like the given example texture. The synthesized texture (right) can be of arbitrary size, and is perceived as very similar to the given ..."
