interesting is we can have an algorithm learn these things by itself and that there is such an algorithm very old ones like a what 16 year old result now do 200 thousand a few called sparse coding you talked about this a bit yesterday did you write cool so now go through this very quickly even a small coding was obviously conceived as like a theoretical neuroscience model so you know Brunello thousand will tell you right he never envisioned that this would be used as a machine learning algorithm this is like a theoretical
