Riassunto analitico
The aim of this thesis is the deepening of the principal clustering techniques and frameworks to process data in streaming and the implementation of a novel fuzzy density based algorithm .
Thesis evolves in three parts.The first part is dedicated to the study and description of principal Apache open source frameworks used for streaming. The second part is devoted to development and comparison between a crisp and a fuzzy version of a streaming algorithm in absence of temporal fading.
In the last part is discussed an online-offline version of the algorithm with temporal fading . In this part online phase collects some aggregations in form of vector of neighbours and vector of borders and offline phase computes clusters at some time intervals.
