About Alfonso

Enthusiast of data and Machine Learning, I have developed models for CERN, where I helped predict failures in the hard drives where LHC information was stored, and for Draper & Dash, in London, helping hospitals in England and Wales predict everything from the expected number of emergencies in a day to the expected length of stay for a patient on the day of admission.
