I work with partial_fit of Birch because the dataset is too huge to load
into memory.

So I cluster data batch by batch. eg: I have 50000 samples and every batch
contain 1000 samples.

I found clustering result is better if I cluster data which contain part of
last batch better than cluster data which doesn't contain previous data.

So I want to know how partail_fit works.
