What is a foundation model?

Trained on very large data sets, foundation models serve as a starting point for developing high performing machine learning models in a quick and cost-effective way.

Foundation models are able to use self-supervised learning and transfer leaning to apply information it has learnt about one situation to another, allowing it to be adaptable for any situation.

How was our foundation model developed?

Our foundation model for histopathology was developed using a similar approach as ChatGPT, starting with data input and having the original input reconstructed by AI to help the AI learn to understand images and their context.

Throughout the process, the data and outputs were verified with pathologists to ensure our model maintained a high level of accuracy.

How does our foundation model impact downstream tasks?

In internal analyses, our foundation model:

  • Reduces the amount of training data/annotations needed to optimize model performance by up to 90%

  • Increased the balanced accuracy of cell classification tasks by an average of ~10% across cell types
