He continued this work at the Rutherford Appleton Laboratory and Yale University as a Postdoctoral Associate.
Data Science at Scale: Harmonized Landsat Sentinel (HLS) Case Study
Most people associate data science as the process of extracting knowledge and insights from data. While that is partly true, data science is a broader concept involving data collection, storage, integration, analysis, inference, communication, and ethics. Gaining a good grasp of these concepts is essential for anyone working in a data-rich field such as Earth science and remote sensing.
This session will explain the complexity of the data life cycle, the supporting data and analytical systems, and the research life cycle. The participants will get a "behind the curtain" view of science data production at scale using the Harmonized Landsat Sentinel-2 (HLS) data as a case study. The lectures will explain the challenges of designing and implementing large-scale processing pipelines on the cloud. A supporting cloud-native analytical platform to enable interactive analysis and visualization will be covered. The concepts of Foundation Model, pre-training, and fine-tuning the model will be covered. The participants will get hands-on experience fine-tuning a foundation model for specific use-cases using HLS data and deploy the trained model to an endpoint for inferencing.
