Is there somewhere on the AICS website where I can find a collection of healthy and unhealthy colony images suitable for benchmarking a machine-learning based classifier?
Hi @gregj, We do not have a set at this moment available on our website. However, maybe one of our scientists may be able to provide images. About how many images of healthy and unhealthy would you need for machine learning?
