Global competition builds AI system to map the human body
Researchers crowdsourced machine learning models from 1,175 teams worldwide to automatically identify tissue structures in microscopy images across different organs. The winning approach could accelerate drug development and disease research by enabling faster, standardized analysis of human tissue samples at scale.
Originaltitel: Segmenting functional tissue units across human organs using community-driven development of generalizable machine learning algorithms
<p>Constructing the human reference atlas requires integration and analysis of massive amounts of data. Here the authors report the setup and results of the Hacking the Human Body machine learning algorithm development competition hosted by the Human Biomolecular Atlas and the Human Protein Atlas teams. The development of a reference atlas of the healthy human body requires automated image segmentation of major anatomical structures across multiple organs based on spatial bioimages generated from various sources with differences in sample preparation. We present the setup and results of the Hacking the Human Body machine learning algorithm development competition hosted by the Human Biomolecular Atlas (HuBMAP) and the Human Protein Atlas (HPA) teams on the Kaggle platform. We create a dataset containing 880 histology images with 12,901 segmented structures, engaging 1175 teams from 78 countries in community-driven, open-science development of machine learning models. Tissue variations in the dataset pose a major challenge to the teams which they overcome by using color normalization techniques and combining vision transformers with convolutional models. The best model will be productized in the HuBMAP portal to process tissue image datasets at scale in support of Human Reference Atlas construction.</p>
