Meet the winners of the Kelp Wanted challenge

DrivenData Labs

Model architectures : All four winners created ensembles of deep learning models and relied on some combination of UNet, ConvNext, and SWIN architectures. In the modeling phase, XGBoost predictions serve as features for subsequent deep learning models. Test-time augmentations were used with mixed results.

We will also discuss best practices for training LLMs, such as using transfer learning, data augmentation, and ensembling methods. LLMs use a combination of machine learning and human input; image from OpenAI Data preparation and preprocessing The first, and perhaps most crucial, step in LLM training is data preparation.
