                         features or on expert knowledge have been proposed to classify 
                         galaxies. The amount of data to be processed in large scale 
                         surveys poses a new challenge for the classification. In this 
                         preliminary study, we investigate machine learning methods for 
                         galaxy image classification. Specifically, we evaluate 
                         convolutional neural networks as tools to be used in the 
                         classification process. Different ways of using convolutional 
                         neural networks has been experimented to classify galaxies as 
                         elliptical or spiral. Classification accuracy around 90-91% for 
                         the Sloan Digital Sky Survey (SDSS) galaxy images has been 
                         achieved.",
