Unsupervised Topographic Learning for Spatiotemporal Data Mining

Abstract EN

In recent years, the size and complexity of datasets have shown an exponential growth.

In many application areas, huge amounts of data are generated, explicitly or implicitly containing spatial or spatiotemporal information.

However, the ability to analyze these data remains inadequate, and the need for adapted data mining tools becomes a major challenge.

In this paper, we propose a new unsupervised algorithm, suitable for the analysis of noisy spatiotemporal Radio Frequency IDentification (RFID) data.

Two real applications show that this algorithm is an efficient data-mining tool for behavioral studies based on RFID technology.

It allows discovering and comparing stable patterns in an RFID signal and is suitable for continuous learning.
