New to TensorFlow: Tails of 2-D Histogram

Hello,

I have data which essentially plots two tails in a 2-D histogram as shown below. I want to build a model that could either identify the two tails by fitting a linear regression between the tails, or something like SVM has been done in the past.

I am fairly new to TensorFlow, and I do not necessarily know where to start with this kind of project. I can provide sample code and data for this as well, if needed.

Thank you!
