The training period needed 512 GB of memory and 8 days on a 64-core Intel Xeon E5-8860 server for a total of 12,288 CPU core hours. If you bought that much processing power on cloud computing it would only cost you $144. After the training period was complete and a winning strategy was found on how to play Poker at a superhuman level then during a real game in real time against real opponents the program only needed 128 GB of memory. </font></div></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div style="font-family:"comic sans ms",sans-serif;font-size:small;color:rgb(0,0,0)"><span class="gmail_default" style="font-family:arial,helvetica,sans-serif">> </span>Can we learn<span class="gmail_default" style="font-family:arial,helvetica,sans-serif"> </span>what it learned? </div></div></blockquote><div> </div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><font size="4">Not really, the program can't tell us why it's so good at what it does for the same reason a human genius can't tell us why he's so good at what he does, neither of them knows.</font></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><font size="4"><br></font></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><font size="4"> John K Clark</font></div>
