Spectral Synthesis for Satellite-to-Satellite Translation

1 code implementation12 Oct 2020 Thomas Vandal, Daniel McDuff, Weile Wang, Andrew Michaelis, Ramakrishna Nemani

These satellites have different vantage points above the earth and different spectral imaging bands resulting in inconsistent imagery from one to another.

High-Dimensional Similarity Search with Quantum-Assisted Variational Autoencoder

no code implementations13 Jun 2020 Nicholas Gao, Max Wilson, Thomas Vandal, Walter Vinci, Ramakrishna Nemani, Eleanor Rieffel

Quantum machine learning is touted as a potential approach to demonstrate quantum advantage within both the gate-model and the adiabatic schemes.

A framework for deep learning emulation of numerical models with a case study in satellite remote sensing

1 code implementation29 Oct 2019 Kate Duffy, Thomas Vandal, Weile Wang, Ramakrishna Nemani, Auroop R. Ganguly

A difficult test for deep learning-based emulation, which refers to function approximation of numerical models, is to understand whether they can be comparable to traditional forms of surrogate models in terms of computational efficiency while simultaneously reproducing model results in a credible manner.

Temporal Interpolation of Geostationary Satellite Imagery with Task Specific Optical Flow

no code implementations28 Jul 2019 Thomas Vandal, Ramakrishna Nemani

Applications of satellite data in areas such as weather tracking and modeling, ecosystem monitoring, wildfire detection, and land-cover change are heavily dependent on the trade-offs to spatial, spectral and temporal resolutions of observations.

Quantifying Uncertainty in Discrete-Continuous and Skewed Data with Bayesian Deep Learning

1 code implementation13 Feb 2018 Thomas Vandal, Evan Kodra, Jennifer Dy, Sangram Ganguly, Ramakrishna Nemani, Auroop R. Ganguly

Furthermore, we find that the lognormal distribution, which can handle skewed distributions, produces quality uncertainty estimates at the extremes.

A Theoretical Analysis of Deep Neural Networks for Texture Classification

no code implementations9 May 2016 Saikat Basu, Manohar Karki, Robert DiBiano, Supratik Mukhopadhyay, Sangram Ganguly, Ramakrishna Nemani, Shreekant Gayaka

To this end, we first derive the size of the feature space for some standard textural features extracted from the input dataset and then use the theory of Vapnik-Chervonenkis dimension to show that hand-crafted feature extraction creates low-dimensional representations which help in reducing the overall excess error rate.

DeepSat - A Learning framework for Satellite Imagery

1 code implementation11 Sep 2015 Saikat Basu, Sangram Ganguly, Supratik Mukhopadhyay, Robert DiBiano, Manohar Karki, Ramakrishna Nemani

Satellite image classification is a challenging problem that lies at the crossroads of remote sensing, computer vision, and machine learning.
