Deep Studying : Write your personal Bible

An Software of Generative Adversarial Networks (GAN)

If you’re planning to begin your personal faith the primary thigh you would want is a holy e book! Now, writing a Holy e book is from scratch is a sedulous job. To finish this drawback you possibly can prepare the GANs mannequin and it’ll do the job for you.

Principally, What I’m making an attempt to indicate is that you just prepare a GANs mannequin to study from any textual content and generate comparable txt out of it.

Right here on this instance, we’re going to use the Holly Bible as coaching information, which is in plain textual content format and will be downloaded from given hyperlink. (https://uncooked.githubusercontent.com/mxw/grmr/grasp/src/finaltests/bible.txt)

Right here is the output(with begin string=’A’) after coaching a single layer GRU for 20 epochs with the default settings under:

And the third a part of the regulation of the Lord Jesus Christ, the God of Israel, and the son of Joseph, and the son of Joseph have been scattered and stated, The primary known as the issues that are within the first day, and the son of man, and the heavens and of the earth, and the sons of Joseph was an organization of the Lord Jesus Christ, and the son of Joseph stated unto him, Lord, what thou hast seen within the LORD our God, and the son of man will not be afraid.

1:15 And the son of man, and the son of Joseph, which is within the religion of the Lord Jesus Christ, and the son of Joseph stated unto him, Lord, what thou hast seen within the LORD our God, and the son of man will not be afraid.

1:15 And the son of man, and the son of Joseph, which is within the religion of the Lord Jesus Christ, and the son of Joseph stated unto him, Lord, what thou hast seen within the LORD our God, and the son of man will not be afraid.

1:15 And the son of man, and the son of Joseph, which is within the religion of the Lord Jesus Christ, and the son of Joseph stated unto him, L

In fact, among the sentences don’t make sense. However, contemplating they seem to similar to the Bible itself.

Creating the mannequin

Prepare the mannequin

This most time taking the duty, and dependents upon the variety of epochs for which you wish to prepare your mannequin. For this instance, we are going to set epochs to solely 20. For every epoch, it took about 100 seconds for me.

for epoch in vary(EPOCHS):
begin = time.time()

# initializing the hidden state initially of each epoch
hidden = mannequin.reset_states()

for (batch, (inp, goal)) in enumerate(dataset):

# feeding the hidden state again into the mannequin
# That is the attention-grabbing step
predictions, hidden = mannequin(inp, hidden)

# reshaping the goal as a result of that is how the
# loss perform expects it
goal = tf.reshape(goal, (-1,))
loss = loss_function(goal, predictions)

grads = tape.gradient(loss, mannequin.variables)
optimizer.apply_gradients(zip(grads, mannequin.variables))

if batch % 100 == 0:
print ('Epoch {} Batch {} Loss {:.4f}'.format(epoch+1,
batch,
loss))
# saving (checkpoint) the mannequin each 5 epochs
if (epoch + 1) % 5 == 0:
checkpoint.save(file_prefix = checkpoint_prefix)
