Additionally, to ensure that advertisers don’t unintentionally encourage such behaviour, they must openly question the platforms about the placement, frequency, and audience of their ads. In terms of policymaking, CCDH notes the U.S. government’s failure to hold social media platforms accountable ...
An absolute value of an ASR exceeding two indicates that the observed frequency in a cell is significantly larger or smaller than expected27. For rational appeals, videos uploaded by amateurs were significantly more likely to include self-efficacy appeals (ASR = 3.5) compared to those ...
附一段原论文,个人感觉理解这一段就可以了。 ok,上面得到了item y的出现间隔预估B,那么frequency estimate就等于 1 / B[y]。 到这里,整篇论文的精华就解释完了。 之后,论文提到了一个streaming frequency estimate的改进方法,主要解决算法2中hash碰撞的问题。也很简单,就是用多个hash,记录多个B,最后用max(Bi)。
