Cluster analysis Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense or another) to each other than to those in other groups (clusters).

- The idea of fixed point clusters (FPCs) is to formalize a cluster as a data subset that does not contain any outlier and with respect to which all other data points are outliers. It is rooted in robust statistics as explained in Section 2. The concept is applied to clusterwise linear regression in this paper.

Clustering: A neural network approach â The FCM clustering (Bezdek, 1974 and Bezdek, 1981), also known as the fuzzy ISODATA (Dunn, 1974), treats each cluster as a fuzzy set, and each feature vector is assigned to multiple clusters with some degree of certainty measured by the membership function.

Marshalling (computer science) Marshalling (computer science) In computer science, marshalling or marshaling is the process of transforming the memory representation of an object to a data format suitable for storage or transmission, and it is typically used when data must be moved between different parts of a computer program or from one program to another.

K-means clustering Clustering is the process of partitioning a group of data points into a small number of clusters. For instance, the items in a supermarket are clustered in categories (butter, cheese and milk are grouped in dairy products). Of course this is a qualitative kind of partitioning.lustering is the process of partitioning a group of data points into a small number of clusters.

DEFINITION of 'Bunching' Often, bunching occurs on the floor of an exchange when multiple round-lot orders or odd-lot orders are combined into one trade execution. The term bunching also refers to a pattern that appears on a ticker tape when a series of same-security trades print one after the other.

Cancer cluster Cancer cluster. A cancer cluster is a disease cluster in which a high number of cancer cases occurs in a group of people in a particular geographic area over a limited period of time. Historical examples of work-related cancer clusters are well documented in the medical literature. Notable examples include: scrotal cancer among chimney sweeps in 18th century London; osteosarcoma among female watch dial painters in the 20th century; skin cancer in farmers; bladder cancer in dye workers exposed to aniline compoun

Cluster analysis When the number of clusters is fixed to k, k-means clustering gives a formal definition as an optimization problem: find the k cluster centers and assign the objects to the nearest cluster center, such that the squared distances from the cluster are minimized.

Difference Between Cluster and Stratified Sampling This would mean additional costs to researchers. Cluster sampling, on the other hand, is a sampling method wherein the population is divided into groups that are already clustered in certain areas or time, and a sample is taken from each group. It can either be a two-stage sampling or multi-stage sampling.

Medical Definition of Cluster headache Cluster headache: A distinctive episodic syndrome of headaches. The most common cluster headache pattern, acute cluster headache, is characterized by one to three short attacks of pain each day around the eyes, clustered over a stretch of 1 to 2 months, and followed by a pain-free period that averages 1 year.

- 1. A cluster is a subset of objects which are “similar”2. A subset of objects such that the distance between any two objects in the cluster is less than the distance between any object in the cluster and any object not located inside it.3. A connected region of a multidimensional space containing a relatively high density of objects.

- In cognitive psychology, chunking is a process by which individual pieces of information are bound together into a meaningful whole (Neath & Surprenant, 2003). A chunk is defined as a familiar collection of more elementary units that have been inter-associated and stored in memory repeatedly and act as a coherent, integrated group when retrieved (Tulving & Craik, 2000).

Pigeonholing Pigeonholing is any process that attempts to classify disparate entities into a small number of categories (usually, mutually exclusive ones). The term usually carries connotations of criticism, implying that the classification scheme referred to inadequately reflects the entities being sorted, or that it is based on stereotypes. Common failings of pigeonholing schemes include: Categories are poorly defined (often because they are subjective). Entities may be suited to more than one category. Example: rhubarb is both 'poisonous' and 'edible'. Entities may not fit into any available category. Example: asking somebody from Washington, DC which state they live in.

Data binning Data binning or bucketing is a data pre-processing technique used to reduce the effects of minor observation errors. The original data values which fall in a given small interval, a bin, are replaced by a value representative of that interval, often the central value. It is a form of quantization. Statistical data binning is a way to group a number of more or less continuous values into a smaller number of bins.

ring topology Definition. Network cabling scheme in which one cable sequentially connects all nodes and forms a closed loop. A data packet starting from the originating node is examined by the next active node if it is addressed to that node. If it does, it is copied, otherwise it is regenerated and passed on to the next node until it reaches back the originating node and is discarded. The ability to regenerate data packets allows a ring topology to span far greater distance than bus or star topologies.
