Phrase Localization Evaluation Demo

This code was tested using Matlab R2016a on a system with Ubuntu 14.04.

Clone the pl-clc repository

git clone --recursive https://github.com/BryanPlummer/pl-clc.git

Follow installation requirements for external code which includes:
On the system this code was tested on only Caffe (in Faster RCNN) and LIBSVM required any compiling to use the evaluation script.
Optional, download the Stanford Parser, putting the code in the external folder naming it stanford-parser. Note that the version of the Stanford Parser used for the precomputed data was 3.4.1.
Download the precomputed data (8.3G): pl-clc models
Get the Flickr30k Entities dataset and put it in the datasets folder. The code also assumes the images have been placed in datasets/Flickr30kEntities/Images.
After unpacking the precomputed data you can run our evaluation code
```
>> evalAllCuesFlickr30K
```
This step took about 45 minutes using a single Tesla K40 GPU on a system with an Intel(R) Xeon(R) CPU E5-2687W v2 processor.

Training new models

There are example scripts that was used to create all the precomputed data in the trainScripts folder. Training these models from scratch requires about 100G of memory. This can be reduced by simply removing some parfor loops, but training the CCA model requires about 70G memory by itself.
