  • Abstract: In this paper, we introduce a new auxiliary Lorentzian space called Kinematic Space, as a geometrical inductive for deep representation learning. Using the non-Euclidean realm for learning representations has gained traction due to their general appeal of handling anatomically hierarchical data. We propose a Gaussian-like distribution that is compatible with gradient-based learning methods and as an application, we formulate a Kinematic space analog of Variational Auto Encoder called $\mathcal{K}_s$-VAE which uses Gaussian-like priors to learn latent representations in our prescribed geometry. We perform experiments on binarized MNIST dataset and report log-likelihood as our evaluation metric. Our experiments are evidentiary for the utility of Kinematic Space in machine learning pipelines.
