ARIMA is not very good for anything but highly predictable time series (of the summer-hot winter-cold kind).

ARIMA is not very good for anything but highly predictable time series (of the summer-hot winter-cold kind).
- aerhardt 3y agoOk but the claim is about high training times… Wtf?
- ugh123 3y agoHigh training times could be cost prohibitive. Currently, its over $100mil to train GPT4 from scratch (which possibly includes other costs related to RLHF and data acquisition). Not sure how this model compares, but its likely not cheap.
- warkdarrior 3y agoThe claim in the paper was the ARIMA has high training times.
- cozzyd 3y agoMaybe they're using a pure Python implementation or something...
- carbocation 3y agoIf true, then beating it and looking good will be easy. Having trained ARIMA models in my day, I will say that long training times and training cost -- compared to any deep learning model -- is not something that ever crossed my mind.
