Many clustering algorithms fail when clusters are of arbitrary shapes, varying densities, or the data classes unbalanced and close to each other, even in two dimensions. A novel algorithm, DenMune is presented meet this challenge. It based on identifying dense regions using mutual nearest neighborhoods size K, where K only parameter required from user, besides obeying neighbor consistency princ...
dimensional Euclidean space. Given N points {xj} in Rd, the algorithm attempts to find k nearest neighbors for each of xj , where k is a user-specified integer parameter. The algorithm is iterative, and its CPU time requirements are proportional to T ·N ·(d ·(log d)+ k · (d + log k) · (log N)) + N · k2 · (d + log k), with T the number of iterations performed. The memory requirements of the proc...
As the healthcare industry becomes more reliant upon electronic records, the amount of medical data available for analysis increases exponentially. While this information contains valuable statistics, the sheer volume makes it difficult to analyze without efficient algorithms. By using machine learning to classify medical data, diagnoses can become more efficient, accurate, and accessible for t...
Distributional similarity is a useful notion in estimating the probabilities of rare joint events. It has been employed both to cluster events according to their distributions, and to directly compute averages of estimates for distributional neighbors of a target event. Here, we examine the tradeoffs between model size and prediction accuracy for cluster-based and nearest neighbors distribution...
