Tensorflow models for Olympic Sports dataset trained with our approach

All models were trained from scratch without Imagenet pretraining and without any supervision.

1. The model trained on all frames from Olympic sports dataset: olympic_sports_all_cat_convnet_scratch_strip.ckpt
2. Using the same method we finetuned the previous model for each sport independently w/o any supervision (we again used only grouping and posets that we build without GT information).
   Single models for each sport: olympic_sports_models_from_scratch

Requirements

• Python 2.7
• Tensorflow r1.*

Example
