This is the Tensorflow (Version 0.11) implementation of AAAI-17 paper "Collective Deep Quantization for Efficient Cross-modal Retrieval". The descriptions of files in this directory are listed below:

• cdq.py: contains the main implementation of the proposed approach cdq.
• train_script.py: gives an example to show how to train cdq model.
• validation_script.py: gives an example to show how to evaluate the trained quantization model.
• run_cdq.sh: gives an example to show the full procedure of training and evaluating the proposed approach cdq.

In data/nuswide/train.txt and data/nuswide/text_train.txt, we give an example to show how to prepare image/text training data. In data/nuswide/test.txt, data/nuswide/text_test.txt, data/nuswide/database.txt and data/nuswide/text_database.txt, the list of testing and database images/texts could be processed during predicting procedure.

The AlexNet is used as the pre-trained model. If the NUS_WIDE dataset and pre-trained caffemodel is prepared, the example can be run with the following command:

"./run_cdq.sh"
