This project is a cleaned up version of our PAMI submission "Deep Metric Learning with BIER: Boosting Independent Embeddings Robustly" in tensorflow. It extends our original ICCV version with an adversarial auxiliary loss during training, which improves results. you are planning to use this work, please cite one of the following papers:

To run the code, see ./run.sh and ./run_eval.sh. The train-images file is a numpy file consisting of images of size 256x256 and train-labels are the corresponding labels. The label indices should be between [0, total-number-of-labels) (i.e. they should be non-negative, and continuous).

The initial weights for the GoogLeNet InceptionV1 model (dumped from the caffe model) is available at: https://files.icg.tugraz.at/d/c3e1a047fc/
