Topic modeling ~= Soft clustering? #2

Open ShiyuZhangGH opened 6 years ago

ShiyuZhangGH commented 6 years ago

I wonder if the topic modeling Blei discussed can be regarded to be similar to the soft clustering (e.g., model-based clustering) discussed in the "flat clustering" chapter?

I would say that topic modeling would fall under soft clustering, since documents don't fit in exactly one cluster ("topic" in this case) but are distributions over clusters/topics
