Matricial Free Energy as a Gaussianizing Regularizer: Enhancing Autoencoders for Gaussian Code Generation
Rishi Sonthalia, Raj Rao Nadakuditi
We introduce a novel regularization scheme for autoencoders based on matricial free energy. Our approach defines a differentiable loss function in terms of the singular values of t…
Free Component Analysis: Theory, Algorithms & Applications
Hao Wu, Raj Rao Nadakuditi
We describe a method for unmixing mixtures of freely independent random variables in a manner analogous to the independent component analysis (ICA) based method for unmixing indepe…
Efficient Sum of Outer Products Dictionary Learning (SOUP-DIL) - The Method
Saiprasad Ravishankar, Raj Rao Nadakuditi, Jeffrey A. Fessler
The sparsity of natural signals and images in a transform domain or dictionary has been extensively exploited in several applications such as compression, denoising and inverse pro…
Efficient Sum of Outer Products Dictionary Learning (SOUP-DIL) and Its Application to Inverse Problems
Saiprasad Ravishankar, Raj Rao Nadakuditi, Jeffrey A. Fessler
The sparsity of signals in a transform domain or dictionary has been exploited in applications such as compression, denoising and inverse problems. More recently, data-driven adapt…
