Understanding Topic Modelling using LSA || Singular Value Decomposition || NLP Data Science

"How would you manage a large corpus of documents??"

There are 2 approaches to it
** Manually segregate the documents into groups or clusters
** Use data science to reduce your burden by 80%

In this video , we try to understand the solution for segregating the documents into groups using topic modelling, an unsupervised clustering approach

We shall also understand
* what latent semantic analysis is
* how singular value decomposition works
