Fast Acquisition for Quantitative MRI Maps: Sparse Recovery from Non-linear Measurements
Anupriya Gogna, Angshul Majumdar
This work addresses the problem of estimating proton density and T1 maps from two partially sampled K-space scans such that the total acquisition time remains approximately the sam…
Analysis and Synthesis Prior Greedy Algorithms for Non-linear Sparse Recovery
Kavya Gupta, Ankita Raj, Angshul Majumdar
In this work we address the problem of recovering sparse solutions to non linear inverse problems. We look at two variants of the basic problem, the synthesis prior problem when th…
Blind Compressive Sensing Framework for Collaborative Filtering
Anupriya Gogna, Angshul Majumdar
Existing works based on latent factor models have focused on representing the rating matrix as a product of user and item latent factor matrices, both being dense. Latent (factor)…
Real-time Dynamic MRI Reconstruction using Stacked Denoising Autoencoder
Angshul Majumdar
In this work we address the problem of real-time dynamic MRI reconstruction. There are a handful of studies on this topic; these techniques are either based on compressed sensing o…
