Deep neural networks building blocks

In this section, we are going to present the key functions that will allow our deep learning project to work. Starting from batch feeding (providing chunks of data to learn to the deep neural network) we will prepare the building blocks of a complex LSTM architecture.

The first function we start working with is the prepare_batches one. This function takes the question sequences and based on a step value (the batch size), returns a list of lists, where the internal lists are the sequence batches to be learned:

def prepare_batches(seq, step):
    n = len(seq)
    res = []
    for i in range(0, n, step):
        res.append(seq[i:i+step])
    return res

The dense function...
