and compute they do some engineering some engineering tricks right here and their results are pretty good so the results in various tasks and we'll we'll look at some of the tasks right here so these are def set results using base size models for example where you can see they do outperform basic roberta models they outperform long former which may mean that the random attention is useful but you know in these things it also always may just mean that you've thrown more compute at it um at least i'm not really looking that
