Machine Learning NYC Neighborhoods

Check out the NYC Neighborhood Predictor!

It uses AWS Machine Learning to predict which neighborhood a string of text originates from.

Overview

• Uses a simple Elixir and Phoenix Web app to expose an AWS Machine Learning Real-Time Endpoint.
• Source Code

Machine Learning What?

• Using a dataset of ~1G of geo-tagged tweets, we create a CSV with two columns: text and neighborhood.
• After training and evaluating a machine learning (ML) model with this data, we expose the real-time endpoint via this elixir application.

Takeaways

• Molding the training data to create a better model is the real challenge here.
• Does my data even have statistical correlations or is it just noise?
• Iterate, iterate, and iterate again on the model and evaluation data is what needs to be done here.
