• I have been using Machine-Learning (Support Vector Regression) to predict
CO2 fluxes across Asia etc.
• I have huge data volume of satellite-data. I really would like to extract some
big changes of terrestrial status. However, not many ideas.
• I have huge data volume of outputs from multiple models. I need to find an
efficient ways to summarize results in a simple way.
• I would like to work model-data integration (data-model fusion) using
satellite-based data as constraints. It takes too much computation time if
we do optimization of parameter.
