Resuming training on a Brain.js Neural Network Model

Question

I am looking to incrementally train a neural net using Brain.js, but can't find a solution using the current version. There is a similar answer to this same problem but it uses a deprecated function parameter keepNetworkIntact. How is this done?

Answer 1

You simply need to import the json into the neural network, and continue training:

const net = new brain.NeuralNetwork();
net.fromJSON(json);
net.train(trainingData, trainingOptions);

The feature was deprecated because we only want to keep the options we absolutely need to keep the api as simple as possible and based off importing json the net can determine what you intend to do next.
