I have been working on implementing a model called Poincaré embeddings over the last month or so. The model is from an interesting paper by Facebook AI Research – Poincaré Embeddings for Learning Hierarchical Representations [1]. This post describes the model at a relatively high level of abstraction, and the detailed technical challenges faced in the process of implementing it. If your goal is instead to understand how and where the model can be used, this tutorial notebook is a more appropriate resource.
