A Python toolbox using deep belief networks for topic modeling on document data, producing latent representations for content-based recommendation.
Deep Belief Nets for Topic Modeling is a Python toolbox that implements deep belief networks for discovering topics in document collections. It transforms bag-of-words representations into latent features that capture semantic relationships between documents, enabling applications like content-based recommendation systems. The project serves as a proof-of-concept implementation based on research presented at the ICML2014 workshop.
Researchers and data scientists working on text mining, topic modeling, and deep learning applications for document analysis. It's particularly relevant for those exploring neural network approaches to natural language processing.
This toolbox provides a specialized implementation of deep belief networks specifically optimized for topic modeling, with tested configurations that work across multiple datasets. It offers a complete pipeline from data preprocessing to visualization, making it easier to experiment with deep learning approaches to document analysis compared to building from scratch.
This repository is a proof of concept toolbox for using Deep Belief Nets for Topic Modeling in Python.

Provides a full workflow from document stemming and bag-of-words generation to DBN training and evaluation, as detailed in the execution order examples in the README.
Saves all intermediate data to disk, allowing training to resume from any point and preventing memory issues, as emphasized in the toolbox philosophy.
Based on a Master's thesis and published research, with clear parameters and execution steps for academic reproducibility, as shown in the linked articles.
Includes PCA-based visualization of document categories in the latent space, with examples like the 20 newsgroups output image in the README.
Many parameters are fixed in the code, limiting flexibility for custom experiments, as admitted in the README's note on hardcoded settings.
Requires manual dataset downloads, specific prerequisite packages, and additional tools like MENCODER for 3D plots, making it less accessible for quick deployment.
Tested on older OS versions like Ubuntu 14.04 and relies on packages that may not be actively maintained, potentially causing compatibility issues.
