ClimateLearn: A machine learning approach for climate prediction using network measures
Abstract. We present the toolbox ClimateLearn to tackle problems in climate prediction using machine learning techniques and climate network analysis. The package allows basic operations of data mining, i.e. reading, merging, and cleaning data, and running machine learning algorithms such as multilayer artificial neural networks and symbolic regression with genetic programming. Because spatial temporal information on climate variability can be efficiently represented by complex network measures, such data are considered here as input to the machine learning algorithms. As an example, the toolbox is applied to the prediction of the occurrence and the development of El Nino in the equatorial Pacific, first concentrating on the occurrence of El Nino events one year ahead and second on the evolution of sea surface temperature anomalies with a lead time of three months.
