train_model | R Documentation |
Trains a VAE or autoencoder model. This acts as a wrapper for keras::fit().
train_model( model, train_data, num_epochs = 10, batch_size = 1, validation_split = 0.15, shuffle = FALSE, verbose = 1 )
model |
the keras model to be trained; this should be the vae returned from |
train_data |
training data; this should be a binary |
num_epochs |
number of epochs to train for |
batch_size |
batch size for mini-batch stochastic gradient descent; default is 1, detailing pure SGD; if a larger batch size is used (e.g. 32), then a larger number of epochs should be set (e.g. 50) |
validation_split |
split percentage to use as validation data |
shuffle |
whether or not to shuffle data |
verbose |
verbosity levels; 0 = silent; 1 = progress bar and epoch message; 2 = epoch message |
a list containing training history; this holds the loss from each epoch which can be plotted
data <- matrix(c(1,1,0,0,1,0,1,1,0,1,1,0), nrow = 3, ncol = 4) Q <- matrix(c(1,0,1,1,0,1,1,0), nrow = 2, ncol = 4) models <- build_vae_independent(4, 2, Q) vae <- models[[3]] history <- train_model(vae, data, num_epochs = 3, validation_split = 0, verbose = 0) plot(history)
