1st Place Solution in Google Universal Images Embedding

Understand

This paper presents the 1st place solution for the Google Universal Images Embedding Competition on Kaggle.

• The highlighted part of our solution is based on 1) A novel way to conduct training and fine-tuning; 2) The idea of a better ensemble in the pool of models that make embedding; 3) The potential trade-off between fine-tuning on high-resolution and overlapping patches; 4) The potential factors to work for the dynamic margin.
• Our solution reaches 0.728 in the private leader board, which achieve 1st place in Google Universal Images Embedding Competition.
