Clustering Gene Expression Data in SQL Using Locally Adaptive Metrics
- …groups of data according to a certain similarity measure. Clustering suers from the curse of dimensionality. It is not meaningful to look for clusters in high dimensional spaces as the average density of points anywhere in input space is likely to be low. As a consequence, distance functions that eq…

Distributed Deviation Detection in Sensor Networks
- …Sensor networks have recently attracted much attention, because of their potential applications in a number of different settings. The sensors can be deployed in large numbers in wide geographical areas, and can be used to monitor physical phenomena, or to detect certain events. An interesting probl…

Locally adaptive metrics for clustering high dimensional data
- …Abstract. Clustering suffers from the curse of dimensionality, and similarity functions that use all input features with equal relevance may not be effective. We introduce an algorithm that discovers clusters in subspaces spanned by different combinations of dimensions via local weightings of featur…
