Super-resolution with Fourier measurements
S. A. Wadood, Shaurya Aarav, Kevin Liang +1
Resolving sources beyond the diffraction limit is important in imaging, communications, and metrology. Current image-based methods of super-resolution require phase information (ei…
New scattering zones in quantum speckle propagation
Shaurya Aarav, S. A. Wadood, Jason W Fleischer
Quantum speckles exhibit significantly richer behavior than their classical counterparts due to their higher dimensionality. A simple example is the far-field speckle pattern in 1D…
The Shape of Attraction in UMAP: Exploring the Embedding Forces in Dimensionality Reduction
Mohammad Tariqul Islam, Jason W. Fleischer
Uniform manifold approximation and projection (UMAP) is among the most popular neighbor embedding methods. The method samples pairs of point indices according to similarities in th…
Outlier Detection in Large Radiological Datasets using UMAP
Mohammad Tariqul Islam, Jason W. Fleischer
The success of machine learning algorithms heavily relies on the quality of samples and the accuracy of their corresponding labels. However, building and maintaining large, high-qu…
