| dc.description.abstract | The explosion of data volume and its expansion speed make tasks of finding knowledge and analyzing data challenging, even more so when non-stationary bases are considered. Although the future values prediction plays a fundamental role in areas such as climate, routing problems and economics, among others, classification seems to be still the most exploited task. Recently, some value-regression algorithms have been launched, for example: FIMT-DD, AMRules, IBLStreams and SFNRegressor; however, their investigative studies have explored more aspects of innovation and analysis of error prediction than exploring their capabilities through criteria that are considered fundamental to data stream, such as elapsed time and memory. In this way, the objective of this work is to present an investigative study about these algorithms that treat regression considering dynamic environments, using massive databases, and also explore the algorithm's adaptability capacity with the presence of concept drift. In order to do this, three databases were analyzed and extended to explore the main evaluation criteria adopted. A wide experiment was carried out, which produced a comparison of the results obtained with the chosen algorithms, allowing to generate behavior indication of each one through the different scenarios to which were exposed. Thus, the main contributions of this work are: evaluation of fundamental criteria: memory, execution time and power of generalization, related to regression to data stream; production of a critical analysis of the algorithms investigated; and the possibility of reproducing and extending the studies carried out by making available the parametrizations applyed. | en |
