Leveraging autocatalytic reactions for chemical-domain image classification

MATLAB code for training and simulating the chemical-based image classification network detailed in our paper:

"Leveraging autocatalytic reactions for chemical-domain image classification" by Christopher E. Arcadia, Amanda Dombroski, Kady Oakley, Shui Ling Chen, Hokchhay Tann, Christopher Rose, Eunsuk Kim, Sherief Reda, Brenda M. Rubenstein, and Jacob K. Rosenstein. Chem. Sci. (2021). https://doi.org/10.1039/D0SC05860B

Requirements

To run this code, the following are required:

MATLAB (tested and developed on R2020b)
CalTech 101 Silhouettes Data Set (download the 16x16 version)

Usage

Download the CalTech 101 data set
update the field database_path in the configure_options.m file with the database location.
Review and optionally edit the other program settings in the configure_options.m file.
Run the script main.m in MATLAB to train and simulate the network.

Also included is a script to analyze the images in the provided dataset (analyze_dataset.m) as well as a script to run multiple classification tests (test_multiple_classifiers.m).

Example

Running the main.m script, after changing the default classes and epoch count to:

option.classes = {'revolver','lamp','mandolin','headphone','umbrella','helicopter','pyramid','chair','saxophone'};
option.epochs = 900;

results in the following weight maps:

and class predictions:
