Opensource solutions and submissions for some of the Kaggle competitions I have participated in. I am ranked 1100th in competitions.
- Global Wheat by University of Saskatchewan - 73rd out of 2245 teams (Top 3%, Silver medal)
- Object detection competition in which we trained models to place bounding boxes over heads of wheat to allow wheat farmers to quickly and accurately gauge harvest size and density.
- My solution incorporated YOLOv4, while my teammates used Efficientdet. Together, we developed robust cross-validation and pseudo labelling to survive the private leaderboard shakedown.
- Writeup and Code
- RSNA-STR Pulmonary Embolism by the Radiological Society of North America - 54th out of 784 teams (top 6.8%)
- Image classification competition in which 3d DICOM CT images of a heart were provided to detect the likelihood of a pulmonary embolism. Provided a unique challenge in the size of the dataset (912gb)
- LSTM stacked ResNeSt to make both 2d (image level) and 3d (CT exam level) predictions.
- Writeup and Code
- Halite by Two Sigma Hedge Fund - 62nd out of 1088 teams (top 6%, bronze medal)
- "Game" type competition in which 4 bots compete to manage resources and gain the most halite in 400 turns. Reinforcement learning, machine learning, and algorithmic bots were common.
- Also see Two Sigma Halite Playground Edition, where I placed first. Code is not currently open source.
