Generalised Spherical Text Embedding
Souvik Banerjee, Bamdev Mishra, Pratik Jawanpuria +1
This paper aims to provide an unsupervised modelling approach that allows for a more flexible representation of text embeddings. It jointly encodes the words and the paragraphs as…
Rieoptax: Riemannian Optimization in JAX
Saiteja Utpala, Andi Han, Pratik Jawanpuria +1
We present Rieoptax, an open source Python library for Riemannian optimization in JAX. We show that many differential geometric primitives, such as Riemannian exponential and logar…
Differentially private Riemannian optimization
Andi Han, Bamdev Mishra, Pratik Jawanpuria +1
In this paper, we study the differentially private empirical risk minimization problem where the parameter is constrained to a Riemannian manifold. We introduce a framework of diff…
Confidence Score for Unsupervised Foreground Background Separation of Document Images
Soumyadeep Dey, Pratik Jawanpuria
Foreground-background separation is an important problem in document image analysis. Popular unsupervised binarization methods (such as the Sauvola's algorithm) employ adaptive thr…
On Riemannian Optimization over Positive Definite Matrices with the Bures-Wasserstein Geometry
Andi Han, Bamdev Mishra, Pratik Jawanpuria +1
In this paper, we comparatively analyze the Bures-Wasserstein (BW) geometry with the popular Affine-Invariant (AI) geometry for Riemannian optimization on the symmetric positive de…
Light-weight Document Image Cleanup using Perceptual Loss
Soumyadeep Dey, Pratik Jawanpuria
Smartphones have enabled effortless capturing and sharing of documents in digital form. The documents, however, often undergo various types of degradation due to aging, stains, or…
