Yesterday night I finished Stanford’s Machile Learning Course. The last two lessons did not include any coding exercise, but the Photo OCR lesson was invaluable: the description of a real problem with the introduction of the pipeline, an engineering concept uncommon in academic world, was a surprise. Also, the cost related questions in the test were fairly basic, but useful to understand how research decisions modify research costs.


Finally, to Prof. Ng: a big thanks from Barcelona. It was great to go back to university and to find such a wonderful teacher.
