Article on new collaborative platforms for software development
One of the most interesting insights from the results of the Netflix challenge is that while the algorithms, the psychology, and good knowledge of statistics goes a long way, it was ultimately the cross-team collaboration that ended the contest. "The Ensemble" team, appropriately named for the technique they used to merge their results consists of over 30 people. Likewise, the runner up team ("BellKor") is a collaborative effort of several distinct groups that merged their results. It is easy to overlook this fact, except that it is not a one-time occurrence. The leaderboard for the recent GitHub contest also clearly shows over half of the top ten entries as ensemble techniques!
