Examples

# NOT RUN {
library(keras)

# input layer
inputs <- layer_input(shape = c(784))

# outputs compose input + dense layers
predictions <- inputs %>%
  layer_dense(units = 64, activation = 'relu') %>%
  layer_dense(units = 64, activation = 'relu') %>%
  layer_dense(units = 10, activation = 'softmax')

# create and compile model
model <- keras_model(inputs = inputs, outputs = predictions)
model %>% compile(
  optimizer = 'rmsprop',
  loss = 'categorical_crossentropy',
