> Well the obvious example is RenTech's Medallion fund which consistently out-performs human stock traders. The article isn't critical of mathematical models, it's specifically critical of deep learning. Is there any evidence that the Medallion Fund uses deep learning? Are there any funds that have said they use deep learning that have a consistent track record of beating the market? My (admittedly anecdotal) understanding is that many, many people have tried using deep learning to predict the market and I'm not aware of anyone who has had long term, consistent success with it.
