Character Wise Generation From The Little Book Of Calm

If you saw the show black books, you saw the calming powers of the little book of calm.
Surprisingly the book actually exists. I extracted the text from the Kindle version and will now train an LSTM with it in order to generate an infinity stream of calming advice. The actual code can be found as a Gist.
For copyright reasons I can not attach the text. So if you want to train this too, you need to buy the Kindle version.
I split all the text into windows of 40 characters and train an LSTM to predict the following character. I use a bidirectional LSTM with a 128 dimensional cell-state. The output mode for the LSTM is many-2-many, which means each input at each time step (the current character) also has an output (the next character). The output is pushed through a dense softmax layer. The LSTM is shown below:
length = 40
step   = 1
model = Sequential()
model.add(Bidirectional(LSTM(128, input_shape=(length, n_char), return_sequences=True), input_shape=(length, n_char)))
model.add(TimeDistributed(Dense(n_char, activation='softmax')))
optimizer = RMSprop(lr=0.01)
model.compile(loss='categorical_crossentropy', optimizer=optimizer)

The Training log is interesting. One can see that the LSTM gets better and better at generation text which can be seen in the notebook. Below I listed some samples. For the sampling, we initialise the generation with a random sequence of 40 characters and let the LSTM generate the rest. The details of the sampling can be seen in the notebook. The text is not great but one can see that the LSTM aims to generate sentences similar to the ones in the book. One might be able to improve it's performance with more layers or more epochs.

However, since the model works on a character level, I am not unhappy with the results:
