Random Projections Model Generation for Document Set

  • Share this:

Code introduction


This function uses the corpora and models modules from the gensim library to create a random projections model for a set of documents. It first converts the documents into a dictionary representation using the Dictionary object and then into a Bag-of-Words (BoW) representation using the doc2bow method. After that, it trains a RandomProjectionsModel instance, which is used for dimensionality reduction and noise reduction.
