[英]visualization for output of topic modelling
For topic modelling I use the method called nmf(Non-negative matrix factorisation). 对于主题建模,我使用一种称为nmf(非负矩阵分解)的方法。 Now, I want to visualise it.So, can someone tell me visualisation techniques for topic modelling.
现在,我想对其进行可视化,所以有人可以告诉我用于主题建模的可视化技术。
Check LDAvis if you're using R; 如果使用的是R,请检查LDAvis。 pyLDAvis if Python.
pyLDAvis如果是Python。 It was developed for LDA.
它是为LDA开发的。 But I guess it also works for NMF, by treating one matrix as topic_word_matrix and the other as topic proportion in each document.
但是我猜想它也适用于NMF,方法是将一个矩阵作为topic_word_matrix,将另一个矩阵作为每个文档中的主题比例。
