That it is 90% cleaning, and only 10% modeling. Never had a dataset that was ready to use like the ones on Kaggle. Most of the time I get a mixture of Excel Sheets with weird formatting, .csv files and SQL dumps that have questionably encoding, and lots of unnecessary information and missing values.
- apohn 8y agoI think Kaggle participants miss out on some of the best parts of being a Data Scientist. Fiddling with data, writing scripts to clean/transform/ingest data, interacting with data owners and subject matter experts, etc. IME that's actually a lot more fun than fiddling with parameters and looking at model performance metrics.
