Implementation for our paper "Conditional Image-Text Embedding Networks"

Conditional Image-Text Embedding Networks

cite contains a Tensorflow implementation for our paper. If you find this code useful in your research, please consider citing:

This code was tested on an Ubuntu 16.04 system using Tensorflow 1.2.1.

We recommend using the data/cache_cite_features.sh script from the phrase detection repository to obtain the precomputed features to use with our model. These will obtain better performance than our original paper as seen in this paper, i.e. about 72/54 localization accuracy on Flickr30K Entities and Referit, respectively. You can also find an explanation of the format of the dataset in the data_processing_example.

You can also find precomputed HGLMM features used in our work here

Training New Models

Our code contains everything required to train or test models using precomputed features. You can train a model using:

python main.py --name <name of experiment>

When it completes training it will output the localization accuracy using the best model on the testing and validation sets. Note that the above does not use the spatial features we used in our paper (needs the --spatial flag). You can see a listing and description of many tuneable parameters with:

python main.py --help

Phrase Localization Evaluation

When testing a model you need to use the same settings as used during training. For example afer training with spatial features, you would have to test using:

python main.py --test --spatial --resume runs/<experiment_name>/model_best

Many thanks to Kevin Shih and Liwei Wang for providing to their implementation of the Similarity Network that was used as the basis for this repo.
