请问有大神知道"
Calculating a score for each item in each step would make the algorithm scale with the product of the number of items and the number of events. This would be unusable in practice. Therefore we have to sample the output and only compute the score for a small subset of the items. This also entails that only some of the weights will be updated " 这个怎么理解?就是为什么计算项目得分来就可以跟新这个权重,或者说这个过程是什么样的?有没有大神解释一下的啊
