How to do Topic Modelling in Python using PySpark LDA
Pyspark integrates the power of spark with python. Latent Dirichlet Allocation is a popular method of Topic Modelling. But it's computation intensive and involves several comparisons.
Topic Modelling is much easier and faster with the integration of Spark & Python.
This video demonstrates with code, how to generate a Topic Model in Python using PySpark for a set of tokenized headlines.
It depicts data flow diagram of Topic Modelling at every stage. Covers the data transformations during data preparation phaseof Pyspark Latent Dirichlet Allocation.
