About Us:

We are a team based in Chicago. We encourage Open Source contributions, especially with the tools we use. We write solid, easily reproducible, testable code. We don’t release on Fridays. 5thColumn offers company sponsored professional training including bootcamps, courseware, books, and conferences. We offer excellent health, dental and vision insurance.

About You:

Ideally, you have experience in machine learning. A 'big tent' term, but we're primarily interested in your ability to find the 'right tool' for the 'right job'. There are projects in the realm of natural language processing (NLP), anomaly detection, time-series forecasting, and beyond!

  • ANOVA
• Experience with linear regression analysis
• A grasp of non- and paramtric classification techniques
  • Discriminant analysis
  • Ensemble methods
  • Neural networks
• Experience with dimensionality reduction
  • Principle Components Analysis (PCA)/Online PCA
  • Singular Value Decomposition (SVD)
• Unsupervised Learning
  • Hierarchical (Agglomarative/Divisive) Clustering
