Pretrained Neural Network Models¶
Despite the source code of TIAToolbox being held under a permissive license, the licenses of model weights are dependent on the datasets that they are trained on. We provide the licenses associated with the utilised datasets, but recommend that users also do their own due diligence for confirmation.
