Our 2020 paper "Forecasting with time series imaging" reached its 100th citation 👏👏👏 We transform time series into images so local features are extracted using CV algorithms & for forecast combinations. Less human intervention but better performance. @XixiLi07 @YanfeiKang 🏆

I asked my son what the biggest number is with three nines? He quickly answered 9^9^9. Then he asked what exactly the number was. I calculated with Python and totally lost. Interestingly I found Python DOES NOT proceed left to right with math 3^3^3 = 3^(3^3) != (3^3)^3.

Went to stat conference: too theorectical, no one will use it in practice; went to data mining conference: where are all the theorectical foundations? A tale of two tastes.
