Harmonization-guided deep residual network for imputing under clouds with multi-sensor satellite imagery

PROCEEDINGS OF 2023 18TH INTERNATIONAL SYMPOSIUM ON SPATIAL AND TEMPORAL DATA, SSTD 2023, pp. 151–160.

By: X. Yang n , Y. Zhao n & R. Vatsavai n 

author keywords: Neural Networks; Imputation; Remote Sensing; Multi-sensor; Knowledge-guided ML
TL;DR: This work presents a knowledge-guided harmonization model that maps the reflectance response from one satellite collection to another based on the spectral distribution of the cloud-free pixels, and presents a novel harmonization-guided residual network to impute the areas under clouds.

Deep Residual Network with Multi-Image Attention for Imputing Under Clouds in Satellite Imagery

2022 26TH INTERNATIONAL CONFERENCE ON PATTERN RECOGNITION (ICPR), pp. 643–649.

By: X. Yang n , Y. Zhao n & R. Vatsavai n 

TL;DR: A novel deep learning-based imputation technique for inferring spectral values under the clouds using nearby cloud-free satellite image observations is presented and it is demonstrated that the ECA method is consistently better than all other methods. (via Semantic Scholar)

2022 article

Multi-stream Deep Residual Network for Cloud Imputation Using Multi-resolution Remote Sensing Imagery

2022 21ST IEEE INTERNATIONAL CONFERENCE ON MACHINE LEARNING AND APPLICATIONS, ICMLA, pp. 97–104.

By: Y. Zhao n, X. Yang n  & R. Vatsavai n 

author keywords: Remote sensing; Cloud imputation; Benchmark; Multi-resolution; Deep learning
TL;DR: A new benchmark data set consisting of images from two widely used and publicly available satellite images, Landsat-8 and Sentinel-2, and a new multi-stream deep residual network (MDRN) fills an important gap in the existing benchmark datasets, which allows exploitation of multi-resolution spectral information from the cloud-free regions of temporally nearby images.

Predictive models with end user preference

Zhao, Y., Yang, X., Bolnykh, C., Harenberg, S., Korchiev, N., Yerramsetty, S. R., … Samatova, N. F. (2021, August 26). STATISTICAL ANALYSIS AND DATA MINING, Vol. 8.

By: Y. Zhao n, X. Yang n , C. Bolnykh n, S. Harenberg*, N. Korchiev n , S. Yerramsetty*, B. Vellanki, R. Kodumagulla, N. Samatova n

author keywords: child support; decision tree; predictive model; regularization; relative ranking; user preference
TL;DR: A generic modeling method that respects end user preferences via a relative ranking system to express multi‐criteria preferences and a regularization term in the model's objective function to incorporate the ranked preferences is proposed. (via Semantic Scholar)
