PANACHE - Physics-based artificial neural network framework for adsorption and chromatography emulation

The python code TrainPANACHE.py trains the physics-based neural network model for constituent steps in cyclic adsorption processes. The code follows the methodology proposed in Physics-based neural networks for simulation and synthesis of cyclic adsorption processes (https://doi.org/10.1021/acs.iecr.1c04731). As an example, relevant training data is provided here to train blowdown step neural network using this code.

FILE LIST

  1. TrainPANACHE.py: Trains physics-based neural networks for constituent steps.
  2. trainfcn.m: Parser function loads train_data.mat and generates train_ads.mat file required for running TrainPANACHE.py.
  3. train_data.mat: .mat data file containing blowdown step spatiotemporal solutions of all state variables.
  4. train_ads.mat: .mat file containing training data for neural network training.

SOFTWARE REQUIREMENTS AND INSTALLATION

Dependencies

The following dependencies are required for the proper execution of this program.

  1. MATLAB version 2019b onwards [required]
  2. Python 3 [required]
  3. Tensorflow v1.15 (GPU) [required]

Installation

  1. Clone the full software package from the GitHub server into the preferred installation directory using:
git clone https://github.com/ArvindRajendran/PANACHE.git

INSTRUCTIONS

  1. Run trainfcn.m (with train_data.mat in the same directory) in MATLAB to generate train_ads.mat.
  2. Run TrainPANACHE.ipyb (with train_ads.mat in the same directory) in Python notebook 3.
  3. Save the weights and biases of the trained model for subsequent use in model predictions.
