The ability to predict short-term electric energy demand would provide several benefits, both at the economic and environmental level. For example, it allow for an efficient use of resources in order face actual demand, reducing costs associated production as well emission CO 2 . To this aim, paper we propose a strategy based on ensemble learning tackle load forecasting problem. In particular, our approach is stacking scheme, where predictions produced by three base methods are used top...

Smart buildings are equipped with sensors that allow monitoring a range of building systems including heating and air conditioning, lighting the general electric energy consumption. Thees data can then be stored analyzed. The ability to use historical regarding consumption could improving efficiency such buildings, as well help spot problems related wasting energy. This problem is even more important when considering some largest consumers In this paper, we interested in forecasting smart...

Feature selection is becoming more and a challenging task due to the increase of dimensionality data. The complexity interactions among features size search space make it unfeasible find optimal subset features. In order reduce space, feature grouping has arisen as an approach that allows cluster according shared information about class. On other hand, metaheuristic algorithms have proven achieve sub-optimal solutions within reasonable time. this work we propose Scatter Search (SS) strategy...

The main motivation for using a multi-objective evolutionary algorithm finding biclusters in gene expression data is motivated by the fact that when looking matrix, several objectives have to be optimized simultaneously, and often these are conflict with each other. Moreover, use of computation justified huge dimensionality search space, since it known algorithms great exploration power.We focus our attention on high quality large variation. This because, analysis, most important goal may...

The electric energy production would be much more efficient if accurate estimations of the future demand were available, since these allow allocating only resources needed for right amount required. With this motivation in mind, we propose a strategy, based on neuroevolution, that can used to aim.
