Estimating Joint Probability Distribution With Low-Rank Tensor Decomposition, Radon Transforms and Dictionaries
Pranava Singhal, Waqar Mirza, Ajit Rajwade +1
In this paper, we describe a method for estimating the joint probability density from data samples by assuming that the underlying distribution can be decomposed as a mixture of pr…
Efficient Data Representation by Selecting Prototypes with Importance Weights
Karthik S. Gurumoorthy, Amit Dhurandhar, Guillermo Cecchi +1
Prototypical examples that best summarizes and compactly represents an underlying complex data distribution communicate meaningful insights to humans in domains where simple explan…
Gradient density estimation in arbitrary finite dimensions using the method of stationary phase
Karthik S. Gurumoorthy, Anand Rangarajan, John Corring
We prove that the density function of the gradient of a sufficiently smooth function , obtained via a random variable transformati…
An application of the stationary phase method for estimating probability densities of function derivatives
Karthik S. Gurumoorthy, Anand Rangarajan, Arunava Banerjee
We prove a novel result wherein the density function of the gradients---corresponding to density function of the derivatives in one dimension---of a thrice differentiable function…
Distance Transform Gradient Density Estimation using the Stationary Phase Approximation
Karthik S. Gurumoorthy, Anand Rangarajan
The complex wave representation (CWR) converts unsigned 2D distance transforms into their corresponding wave functions. Here, the distance transform S(X) appears as the phase of th…
