data quality has become the fundamental law of training ✔️

So true! Having excellent data is one of those things that is overlooked until you try to build ML / AI models on real data. You can get so much signal from good feature engineering and leveraging domain knowledge to add fields that matter to the data.

lol this one is too real. Constantly have to explain to other people at my job that spending days reviewing the data is not low status and outsourcing someone else to do it that’s not responsible for model performance would be actively harmful
