Celebrating 10 million downloads of Facebook Prophet! By the time this reaches your feed, PePy will be reporting that #facebook's #prophet package will have been downloaded an astonishing 10,000,000 times (https://lnkd.in/grs6cyiV). I don't remember the author's exact words when responding to my critique of the package, but it was along the lines of "this post rips prophet to shreds and I agree with all of it". It is also true that nobody has been able to build anything resembling a remotely convincing case for Prophet's efficacy. But you can't deny the success based on user adoption. This paradox requires an explanation, and if that means pushing back on my observations, that's fine by me. (I also think it was an original contribution, with many interesting generalizations). What explains the popularity? #timeseries #timeseriesanalysis #forecasting #opensource
