What is public lb in Kaggle?

Actually the public LB is computed on a portion of the test set, the private is computed on the remainder of the test set (not the whole test set). “Fitting the LB” is a Kaggle term used to describe when you’re tuning your models to perform well on the public LB.

How is Kaggle score calculated?

The score you get is calculated on a subset of testing set, which is commonly referred to as a Public LB score. Whereas the final result will use the remaining data in the testing set, which is referred to as a Private LB score. The score you get by local cross validation is commonly referred to as a CV score.

What’s the difference between public and private Kagglers?

There is an art and a science in doing so and experience Kagglers are able to make the most out of it without overfitting. If not done well, that usually lends itself to worse scores on the private LB, sometimes disasters. In general the key is to build a model that generalizes well. Local cross validation is essential for that. But t
