Everything Flows yet is Traceable – I explore this aspect in the context of data mining as well in the context of software projects.
ABOUT MY WORK
Multi Algorithm Voting for better Segmentation. Multi Algorithm Voting (MAV) is a decision support method and tool, enables presentation, comparison and evaluation of multi-algorithm outputs derived from widely diverse algorithms.
Cluster Evolution Analysis. Cluster analysis is often performed at a specific point in time, without taking into account previous cluster analysis products. Cluster Evolution Analysis proposes a model that addresses three phenomena likely to occur over time: 1) changes in the number of clusters; 2) changes in cluster characteristics; 3) between-cluster migration of objects.
Dynamic Updating of Classifier Rules via Small Memory Buffers. In big data environment, training of a classifier cannot use “brute-force-processing” (in real-time nor off-line). For this purpose we propose a method and a system for an ongoing updating of classification rules based on incremental processing of “dynamic “samples” stored in the small memory buffers.
