Hey all,
I just posted my results to the Kaggle forums, https://www.kaggle.com/c/favorita-grocery-sales-forecasting/discussion/47185#266883
tl;dr - I never got better than .547 on the LB with a simple NN using just 4 features, although I learned a ton trying to replicate the approach @jeremy outlined in the Rossman example. Above I shared what I tried and what did/didn’t work.
Happy to share one of my many other notebooks if it helps.
