https://github.com/wechaty/wechaty-puppet-padplus/issues/226#issuecomment-630093877 @su-chang it's essential in our use case to show proper large thumbnail and Mini App name. If it is feasible, can you point the direction? we can submit PR.

@su-chang I see. We are using `donut` in our daily work now, since `donut` is still under development, we compared `padplus` to see if it's more robust.

Rephased my question, also found some discussion here: http://stats.stackexchange.com/a/108990

@DrDub thanks for your reply. I set smoothing to 0.01 and keep different training set balanced, overall it works well. Still, looking forward to the new Good Turing smoothing. 👍
