Study Design Flowchart

The study was designed in 3 phases consisting of data collection, development of the neural network, and assessment of the network. Development of the neural network was divided into 2 stages. Stage 1 involved selecting the optimal network design. Stage 2 involved training the “final” model, which is then assessed using the unseen “test set”, allowing a comparison with humans.
