Successive Embedding and Classification Loss for Aerial Image Classification

1 code implementation5 Dec 2017 Jiayun Wang, Patrick Virtue, Stella X. Yu

To address the overfitting problem in aerial image classification, we consider the neural network as successive transformations of an input image into embedded feature representations and ultimately into a semantic class label, and train neural networks to optimize image representations in the embedded space in addition to optimizing the final classification score.

Better than Real: Complex-valued Neural Nets for MRI Fingerprinting

no code implementations1 Jul 2017 Patrick Virtue, Stella X. Yu, Michael Lustig

The task of MRI fingerprinting is to identify tissue parameters from complex-valued MRI signals.

On the Empirical Effect of Gaussian Noise in Under-sampled MRI Reconstruction

no code implementations3 Oct 2016 Patrick Virtue, Michael Lustig

The effects of lower SNR and the underdetermined system are coupled during reconstruction, making it difficult to isolate the impact of lower SNR on image quality.
