two new threads on Kaggle

[radekosmulski]

Posted two new threads to kaggle with my thoughts on the birdcall competition:

• what works in this competition?!
• tackling domain adaptation head on is tough - what else can we do?

Cross posting them here as I feel they give a good update on where I find myself in the competition and on the next steps (in particular, test driving improving the train set through the use of dl-annotator)
