This code was tested on an Ubuntu 16.04 system using Pytorch version 0.1.12. It is based on the official implementation of the Conditional Similarity Networks paper.

Usage

You can download the Polyvore Outfits dataset including the splits and questions for the compatibility and fill-in-the-blank tasks from here (6G). The code assumes you unpacked it in a dictory called data, but if you choose a different directory simply set the --datadir argument. You can see a listing and description of the model options with:

    python main.py --help

Using a pre-trained model

We have provided a pre-trained model for the nondisjoint data split which you can download here (11M). This model learns diagonal projections from the general embedding to a type-specific compatibility space which is L2 normalized after appying the projection. You can test this model using:

    python main.py --test --l2_embed --resume runs/nondisjoint_l2norm/model_best.pth.tar

This code includes some minor modifications resulting in better perfromance than the version used for our camera ready. For example, our pre-trained model should provide a compatibility AUC of 0.88 and fill-in-the-blank accuracy of 57.6, which is a little better than the 0.86 AUC/55.3 accuracy for our best model reported in our paper.

Training a new model

To train the pre-trained model above we used the following command.

    python main.py --name {your experiment name} --learned --l2_embed

By default the code outputs the results on the test set after training. However, if you wanted to re-run the test for many settings you have to use the same flags during testing as you had during training. For example, if you trained with the --use_fc to train fully connected type-specific embeddings rather than a (diagonal) mask, at test time you would use:

   python main.py --test --use_fc --resume runs/{your experiment name}/model_best.pth.tar
