Experiments in thermonuclear fusion generate thousands of signals. Machine learning techniques have shown to be very suitable for implementing pattern recognition systems to fusion databases. The huge amount of data involves performing the analysis in high-dimensional spaces. This makes difficult the searching of patterns with similar properties, which normally produces overfitting. During last years, the use of boosting algorithms has become very popular for avoiding overfitting and building generalized data-driven models. Boosting allows achieving a highly accurate, robust and fast classification by combining many relatively simple rules. In this work, we propose the use of Adaboost algorithm to classify Thomson Scattering images of the fusion device. The results are compared with previous works on similar databases.
