def autoencoder_training (X_train, Y_train, epochs):
history autoencoder.fit (# YOUR CODE HERE)
return history

Options:

i. autoencoder.fit(X_train, Y_train, epochs=epochs)

ii. autoencoder.fit(Y_train, Y_train, epochs=epochs)

iii. autoencoder.fit(Y_train, X_train, epochs=epochs)

iv. autoencoder.fit(X_train, X_train, epochs=epochs)
