Hi,

I am training the network on NVIDIA Tesla GPU with a batch size of 1. I am training for 500K iterations, it's taking huge time, around some 600 hours. I listed below the parameters I used.
batch_size = 1
sequence_max_length = 100
words_count = 256
word_size = 32
read_heads = 4
learning_rate = 1e-4
momentum = 0.9

Any suggestions on how to improve the training time?

Thanks

hi there
is it possible for you point me out some resorces to include externals embeddings from word2vec?, in order to transfer some learnign from a particular field in the bay task or any other.
thanks a lot

Hello,

The output sequence length in the implementation is the same as the input sequence length. Perhaps I have misunderstood, but is this a required feature? In the BaBi task for example, in the target you simply replace the "-" symbols with the correct word and leave all other words the same, thereby leaving the sequence length identical.

How could one predict an output sequence of different length to the input (many-to-many), or just 1 output timestep (many-to-one)? For the latter case, would you just take the last timestep in the output?

Thanks!

I would like to train a copy task for a non binary sequence. For example, for a sequence containing random numbers between [0, 1]. What loss function would you suggest? MSE? Iterations and lr should also be adjusted, right?

Trying to train a model that copies a 10x1 vector, the loss converges, however the read weights seem to be fade. Why is this happening? (I changed memory_words_num to 20, and memory_word_size to 20)

Hello. This is a very good code. But I am very curious about why use FeedforwardController instead of the original BaseController. Is there small specific function?

def pack_into_tensor(array, axis):
    """
    packs a given TensorArray into a tensor along a given axis
    Parameters:
    ----------
    array: TensorArray
        the tensor array to pack
    axis: int
        the axis to pack the array along
    Returns: Tensor
        the packed tensor
    """

    packed_tensor = array.pack()
    shape = packed_tensor.get_shape()
    rank = len(shape)

    dim_permutation = [axis] + range(1, axis) + [0]  + range(axis + 1, rank)
    correct_shape_tensor = tf.transpose(packed_tensor, dim_permutation)

    return correct_shape_tensor

Imagine I want to stack a tensorArray with 6 elements of shape [3,4,5] into a tensor of shape [3,4,5,6]. Axis is 3. After array.pack(), the shape of tensor is [6,3,4,5]. dim_permutation is [3] + [1,2] + [0] + [] = [3,1,2,0]. After transpose, the output shape is [5,3,4,6], which is wrong.

The correct formula should be

dim_permutation = range(1, axis+1) + [0] + range(axis+1, rank)

With this formula, the dim_permutation is [1,2,3] + [0] + [] = [1,2,3,0].

Similarly, the formula in unpack_into_tensorarray is also wrong. The correct code should be

dim_permutation = [axis] + range(0, axis) + range(axis+1, rank)

Please take a look. Thanks

We notice that in the paper, the memory is a 2D matrix, but in pratice, the memory is a 3D tensor ([batch size, cell number, memory size]). Maybe I ignore some import detail. Could you help me address my confusion? Thank you

While implementing bAbI task based on your code,
I've found that the sequence length is defined as a single integer for each batch in dnc.py.

For copy task, you fed the same length items for each batch (though its random),
but if each item in one batch varies in their length (like sentences in bAbI), shouldn't it be array of sequence lengths? (size of batch)

I successfully run the program.However, I found threre is something seen abnormal.

class RecurrentController(BaseController):
def network_vars(self):
self.lstm_cell = tf.nn.rnn_cell.BasicLSTMCell(256)
self.state = self.lstm_cell.zero_state(self.batch_size, tf.float32)

def network_op(self, X, state):
    X = tf.convert_to_tensor(X)
    return self.lstm_cell(X, state)

def get_state(self):
    return self.state

def update_state(self, new_state):
    return tf.no_op()

In the above, tf.nn.rnn_cell.BasicLSTMCell(256) make 256 lstm cells, but the code directly use return self.lstm_cell(X, state) without using tf.static_rnn or tf.nn.dynamic_rnn.
tf.static_rnn or tf.nn.dynamic_rnn can output state, but self.lstm_cell(X, state) can't.
I wonder whether it's wrong and needed to add tf.static_rnn or tf.nn.dynamic_rnn as following:

def network_op(self, X, state):
X = tf.convert_to_tensor(X)
return return tf.nn.dynamic_rnn(self.lstm_cell, X, initial_state=state, time_major=False)

Hi @Mostafa-Samir,

thanks a lot for your code, it has not only helped me to understand the topic, but it also provides a really nice and clean approach for solving the problem of having different sequence lengths.

I used your code structure and organization to replicate the initial Neural Turing Machine approach. You can find it here. I made all the proper references, hope you don't mind.

Best.,

In the train.py code, it is possible to train a sequence with random length. Would it be possible to train a sequence with random input_size?

Hey guys!

Thanks a lot for sharing this! I switched to TF 1.0 and upgrading your code is not entirely straightforward (the upgrade script leaves several places to be dealt with manually). I can probably manage but perhaps others have similar issues and it would help us if you released also a 1.0 version.

Thanks for considering this!

I am trying to fallow Project Structure and Usage but complete running examples would help
I ran the code with no output to Initial Transformation Weights that I skipped the defalts would probably be ok.
I tried
import dnc/dnc
this seems to import dnc
import dnc
that had errors
I am here and it shows errors when I put this at the end of my code.
How to prepare some data for this would help if that is what I need to do to make use of it.

Congratulations, @Mostafa-Samir.

This implementation of the DeepMind DNC works like a charm. I've tested it with a new task for the model learning and generalizing a pseudo-code like this:

function(x):
if (x == 1)
return (near) 1.0 (float values)
else
return (near) 0.0 (float values)

I did it in this way (the model learns this function in less than 1000 iterations!!):

Common Settings

The model is trained on 2-layer feedforward controller (with hidden sizes 128 and 256 respectively) with the following set of hyperparameters:

• RMSProp Optimizer with learning rate of 10⁻⁴, momentum of 0.9.
• Memory word size of 10, with a single read head.
• A batch size of 1.
• input_size = 3.
• output_size = 1.
• sequence_max_length = 100.
• words_count = 15.
• word_size = 10.
• read_heads = 1.

A square loss function of the form: (y - y_)**2 is used. Where both 'y' and 'y_' are scalar numbers.

The input is a (1, random_length, 3) tensor, where the 3 is for a one-hot encoding vector of size 3, where:

010 is a '0'
100 is a '1'
001 is the end mark

So, and example of an input of length 10 will be the next 3D-tensor:

[[[ 0. 1. 0.]
[ 0. 1. 0.]
[ 0. 1. 0.]
[ 1. 0. 0.]
[ 0. 1. 0.]
[ 0. 1. 0.]
[ 1. 0. 0.]
[ 0. 1. 0.]
[ 0. 1. 0.]
[ 0. 0. 1.]]]

This input is a represenation of a sequence of adding 0 or 1 values in the form of:

0 + 0 + 1 + 0 + 0 + 1 + 0 + 0 + (end_mark)

The target outoput is a 3D-tensor with the result of this adding task. In the example above:

[[[2.0]]]

The DNC output is a 3D-tensor of shape (1, random_length, 1). For example:

[[[ 0.45]
[ -0.11]
[ 1.3]
[ 5.0]
[ 0.5]
[ 0.1]
[ 1.0]
[ -0.5]
[ 0.33]
[ 0.12]]]

The target output and the DNC output are both then reduced with tf.reduce_sum() so we end up with two scalar values. For example:

Target_output: 2.0
DNC_output: 5.89

And we apply then the square loss function:

loss = (Target_o - DNC_o)**2

and finally the gradient update.

Results

The model is going to recieve as input a random length sequence of 0 or 1 values like:

Input: 1 + 0 + 1 + 1 + 0 + 0 + 0 + 0 + 1

Then it will return a scalar value for this input adding proccess. For example, the DNC will output something like: 3.98824.
This value will be the predicted result for the input adding sequence (we are going to truncate the integer part of the result):

DNC prediction: 1 + 0 + 1 + 1 + 0 + 0 + 0 + 0 + 1 = 3 [3.98824]

Once we train the model with:

$python tasks/copy/train.py --iterations=50000

we can see that the model learns in less than 1000 iterations to compute this adding function, and the loss drop from:

Iteration 0/1000
Avg. Logistic Loss: 24.9968

to:

Iteration 1000/1000
Avg. Logistic Loss: 0.0076

It seems like the DNC model is able to learn this pseudo-code:

function(x):
if (x == [ 1. 0. 0.])
return (near) 1.0 (float values)
else
return (near) 0.0 (float values)

Generalization test

We use for the model a sequence_max_length = 100, but in the training proccess we use just random length sequences up to 10 (sequence_max_length/10). Once the train is finished, we let the trained model to generalize to random length sequences up to 100 (sequence_max_length).

Results show that the model successfully generalize the adding task even with sequence 10 times larger than the training ones.
