Latent Dirichlet Allocation(LDA) is one of the most common algorithms in topic modelling. LDA was proposed by J. K. Pritchard, M. Stephens and P. Donnelly in 2000 and rediscovered by David M. Blei…
I think there are some very interesting new approaches to topic modelling right now, and BERTopic is a great example of that. Another option you can explore is Top2Vec (https://github.com/ddangelov/Top2Vec) which…...Read More 1 reply Reply More from Dan Robinson and Towards Data ...

So for topic 1, 'learning', 'modelling' and 'statistics' might be some of the most common words. This means that you could then say that this is the 'data science' topic. For topic 2, the words 'GPU', 'compute' and 'storage' could be the most common words. You could interpret ...
