The data preparation phase is a critical step in the KDD (Knowledge Discovery in Databases) process. This phase is crucial for a good data mining result because if data is not correctly prepared, all the next phases of the process are compromised. DMPML is a framework that stores preprocessed data for different data mining algorithms in an XML document and(More)
This paper proposes a new reinforcement learning algorithm called TD-GNG that uses the Growing Neural Gas (GNG) network to deal with environments of large domains. The proposed algorithm is capable to reduce the dimensionality of the problem by aggregating similar states. In experimental comparison against tile-coding in mountain car and puddle world, the(More)
