Tutorial

To run this tutorial you need to run jupyter.

If you run jupyter remotely, you can use jupyter notebook --ip=0.0.0.0

Main file: visual_turing_test.ipynb The reader is however encouraged to download the notebook together with the associated files and go through the tutorial on his own.

The tutorial should be run on a Linux machine. Please also make sure that all Installation requirements are fullfiled and you have similar versions of Theano and Keras (see 'Tested on').

Please contact mmalinow@mpi-inf.mpg.de if you encounter any problems.

Kraino - Keras-based RNN for Visual Turing Test

Keras implementation of the 'Ask Your Neurons'.

Free software: MIT license
If you use this library, please cite our "Ask Your Neurons" paper [1]
Note that we use a simplified version of Kraino for the purpose of the Tutorial

Installation

Requirements:

Theano
Keras (fchollet)
toolz
h5py
Bokeh (0.10.0)
nltk (required by WUPS metrics)
pydot
spacy

Additional:

VQA (VT-vision-lab/VQA) for Visual Question Answering
- vqaEvaluation for the evaluation metrics
- vqaTools for the dataset providers
- both should be placed in the kraino/utils folder

source code and local ouput
local
- stores logs (e.g. predictions) in the 'logs' folder
- stores weights of different models in the 'weights' folder
- stores model topologies as '.pkl' files
kraino
- stores the models in the 'core' folder
- stores functions (dataset providers or callbacks) in the 'utils' folder

Eras

It counts a computational cycle in eras (not epochs). Every era ends when "MAX EPOCH" is reached, then the training proceeds to the next era. Before and after each era the (callback) actions are executed.

Warning

The framework is under the continous development, and hence it is not warranted that API won't change in the future. To avoid adaptations to new API, you can clone from a specific commit hash.
