Realized I had been feeding my AI training data backwards for 6 months
Last week I ran a model validation and got a 20% accuracy hit. Turned out I was feeding the training data in reverse chronological order the whole time. Anyone else deal with a basic setup mistake that took forever to catch?

Hold up, you were feeding it in reverse for SIX MONTHS? That's insane. The model must have been basically learning a time-reversed version of the data, which is wild to think about. What kind of weird patterns or predictions did it spit out before you caught it?
