Using Machine Learning and NodeJS to detect the gender of Instagram Users

The goal of this article is to provide a very practical guide to deploying a machine learning solution at scale. Not everything is proven right or optimal, and as with any real-life deployment, we made some trade-offs and took some shortcuts on the go without necessarily building all the evidence that would have been required in an academic setting. We apologize for that, and we will try to clearly point out throughout the post the places where we did so and hope that it will be helpful to you nonetheless.
