"機械學習" (The random-forest approach)預測世界盃足球賽盟主 Machine learning predicts World Cup winner

世界盃足球賽周四登場，觀眾人數可能勝奧運。
預測盟主是場大賭，投注站以巴西、德國、西班牙圍主流說法。
除了上述各種傳統的戰局統計分析法，現在加入"機械學習"新預測工具：

The random-forest approach is different. Instead of calculating the outcome at every branch, the process calculates the outcome of random branches. And it does this many times, each time with a different set of randomly selected branches. The final result is the average of all these randomly constructed decision trees.
