Main notes
The DPX project provides easy solutions to interface AI with numerical simulations.
The project provides a Core
package with additional compatibility layers for external AI and simulations frameworks.
The project includes three main AI pipelines:
- Generate a dataset with synthetic data from numerical simulations;
- Train an artificial neural network with a synthetic dataset;
- Use the prediction of trained networks in a numerical simulation.
This version is the first stable release of the project.
It provides a Core
package with 2 corresponding SOFA & PyTorch compatible layers. It also provides a documentation page and examples with shared training data.
Features
Dataset
- Automatic training dataset storage and loading with multiple files management;
- Dataset shuffle and normalization;
- Multiple dataset modes: Training, Validation, Prediction;
- Customizable dataset fields.
Simulation
- Data generation achieved by several simulations running in multiprocessing with a client-server architecture;
- Operation with internal data, from the dataset or from the neural network;
- Increased interactions with other components (dataset, neural network, visualizer);
- Check the validity of the training data;
- A visualization Factory to init, update and render the simulated objects (written with Vedo).
Network
- Automatic storage and loading of networks during training;
- Customizable data transformations at each step (forward pass, optimization, prediction apply);
- Customizable optimization process with training data;
- An analysis of the evolution of the training session (written with Tensorboard);
- Already implemented architectures: FC, UNet.
