Just-In-Time Analytics on Large File and Storage Systems

Traditional file systems, such as NTFS and ext3, often struggle to support complex analytics due to limited metadata and the absence of global views. Performing aggregate or top-k queries typically requires exhaustive scanning or pre-built indexes, which are time-consuming and resource-intensive. These limitations hinder efficient data management and...

Gaussian Process Modeling for Heterogeneous Functions

Many modern science and engineering applications, such as machine learning, hyperparameter optimization of neural networks, robotics, cyber-physical systems, etc., call for modeling techniques to model black-box functions. Gaussian Process (GP) modeling is a popular Bayesian non-parametric framework heavily employed to model expensive black-box functions...

Algorithm for Improved Differentiable Hyperspectral Unmixing

Background Hyperspectral unmixing—a method of imaging where light radiance is densely sampled at multiple wavelengths—is an important remote sensing task with applications including material identification and analysis. Characteristic spectral features make many pure materials identifiable from their visible-to-infrared spectra, but quantifying...
