• Abstract summary: The model is fully interpretable and is able to do state prediction for both climate and crop dynamics in the greenhouse over a long time horizon. We propose a procedure to solve the differential equations, handle the problem of missing unobservable states in the data, and train the model efficiently.

• Abstract: We present a differentiable greenhouse simulation model based on physical processes whose parameters can be obtained by training from real data. The physics-based simulation model is fully interpretable and is able to do state prediction for both climate and crop dynamics in the greenhouse over very a long time horizon. The model works by constructing a system of linear differential equations and solving them to obtain the next state. We propose a procedure to solve the differential equations, handle the problem of missing unobservable states in the data, and train the model efficiently. Our experiment shows the procedure is effective. The model improves significantly after training and can simulate a greenhouse that grows cucumbers accurately.

  Simulation-based inference ( SBI) is capable of approximating the posterior distribution that relates input parameters to a given observation. In this work, we consider a tall data extension in which multiple observations are available to better infer the parameters of the model. We compare our method to recently proposed competing approaches on various numerical experiments and demonstrate its superiority in terms of numerical stability and computational cost.

  upcoming exascale era will provide a new generation of physics simulations with high resolution. These simulations will have a high resolution, which will impact the training of machine learning models since storing a high amount of simulation data on disk is nearly impossible. This work presents an approach that trains a neural network concurrently to a running simulation without data on a disk.

• Long-term stability and generalization of observationally-constrained stochastic data-driven models for geophysical turbulence [0.19686770963118383]
  Deep learning models can mitigate certain biases in current state-of-the-art weather models. Data-driven models require a lot of training data which may not be available from reanalysis (observational data) products. deterministic data-driven forecasting models suffer from issues with long-term stability and unphysical climate drift. We propose a convolutional variational autoencoder-based data-driven model that is pre-trained on an imperfect climate model simulation.
