Solution to HackerRank WalmartLabs Codesprint (Machine Learning)

Problem Name: Products on Virtual Shelves

For now this repo only contains the abridged version of code that generated my final submission, with non-essential analytics and visualization removed. In the future I might do some cleanup and put in those code for reference.

Suggestions and PR are welcomed.

Prerequisites

• R
  • pacman
• Python
  • pandas >= 0.19.0
  • scikit-learn >= 0.18
  • keras (latest)
  • scipy >= 0.18.1
  • numpy >= 1.11.2
  • jupyter >= 1.0.0

How to reproduce

1. Put train.tsv and test.tsv into data folder
2. Rscript prepare_labels.R
3. Run FinalSubmission.ipynb in Jupyter

Possible Future Works

1. Ensemble with other models
2. Advanced Text Processing: nltk, spacy...
