Kaggle

Kaggle Notebook

You can write up to 20 GB to the current directory (/kaggle/working/) that get preserved as output when creating a version with “Save & Run All”. You can also write temporary files to /kaggle/temp/ but they won’t be saved outside of the current session.

How to Win a Kaggle Competition

1. A good validation set
2. Solid baseline model
3. Ensembling: the final piece of the puzzle is ensembling. The idea behind it is very straightforward. We want to combine predictions from multiple models in the hopes that their errors are not correlated. If model A makes different errors than model B, some of them will cancel out each other. Using a diverse set of models helps. Kaggle Ensembling Guide
4. Use %%timeit to profile your code (see Jupyter tips)
