SEQUENTIAL PATTERN ANALYSIS IN DYNAMIC BUSINESS
... Our major contribution is to identify the right granularity for sequential pattern analysis. We first show that the right pattern granularity for sequential pattern mining is often unclear due to the so-called “curse of cardinality”, which corresponds to a variety of difficulties in mining sequentia ...

Clustering Techniques Data Clustering Outline
... – The best known neural network approach to clustering is the SOM (self-organizing feature map) method, proposed by Kohonen in 1981. – It can be viewed as a nonlinear projection from an mdimensional input space onto a lower-order (typically 2-dimensional) regular lattice of cells. Such a mapping is ...

An immediate implication of this result is that two individuals who observe the same sequence of signals will ultimately agree, even if they start with very different priors. Despite this powerful intuition, disagreement is the rule rather than the exce ...
