Chaii - Hindi and Tamil Question Answering Kaggle Competition Solution
I trained all my models via jupyter notebooks. The notebooks used to train the models from my final ensemble are saved in the training_notebooks folder.
The notebooks refer to the following csv files:
tydiqa_train.csv.zip- this file can be recreated by executing this notebook: https://www.kaggle.com/thedrcat/tydi-qa-downloadnq_small.csv.zip- I published this dataset here: https://www.kaggle.com/thedrcat/nqsmallchaii_mlqa_xquad_5folds.csv- this comes from the following dataset: https://www.kaggle.com/zacchaeus/chaiimlqaxquad
In some instances I used an interim checkpoint when both local CV and public LB indicated it's better than final checkpoint. The following table illustrates that. Note that due to some potential randomness I'd recommend to watch validation when reproducing the results.
