Lung cancer early detection is a vital task which is made difficult by the small size of 
pulmonary nodules, the detection of which on thousands of 
CT scans every day is excessively time-consuming. 
Computer-aided lung nodule classification can dramatically boost the speed of diagnosis. Recommended solution starts from bidimensional images obtained from CT scan and displaying 
suspicious nodules areas: these are inserted into an 
autoencoder, from which two hundred dimensional features are extracted. These 
learned features are then confronted with a 
trained classifier to produce the final lung nodules classification.
