Topic modelling is a subsection of natural language processing (NLP) or text mining which aims to build models in order to parse various bodies of text with the goal of identifying topics mapped to the text. These models assist in identifying big picture topics associated with documents at sca...

Gensim can process arbitrarily large corpora, using data-streamed algorithms. There are no "dataset must fit in RAM" limitations. Platform independent Gensim runs on Linux, Windows and OS X, as well as any other platform that supports Python and NumPy. ...
python BERT topic 模型 bert pytorch源码 众所周知,BERT模型自2018年问世起就各种屠榜,开启了NLP领域预训练+微调的范式。到现在,BERT的相关衍生模型层出不穷(XL-Net、RoBERTa、ALBERT、ELECTRA、ERNIE等),要理解它们可以先从BERT这个始祖入手。 HuggingFace是一家总部位于纽约的聊天机器人初创服务商,很早就捕捉到BERT...
Each of the $$M$$ topics is represented by a vector of length $$V$$ that details which words are likely to occur, given a document on that topic. So for topic 1, 'learning', 'modelling' and 'statistics' might be some of the most common words. This means that you could then say...
