- Abstract: In routine colorectal cancer management, histologic samples stained with
hematoxylin and eosin are commonly used. Nonetheless, their potential for
defining objective biomarkers for patient stratification and treatment
selection is still being explored. The current gold standard relies on
expensive and time-consuming genetic tests. However, recent research highlights
the potential of convolutional neural networks (CNNs) in facilitating the
extraction of clinically relevant biomarkers from these readily available
images. These CNN-based biomarkers can predict patient outcomes comparably to
golden standards, with the added advantages of speed, automation, and minimal
cost. The predictive potential of CNN-based biomarkers fundamentally relies on
the ability of convolutional neural networks (CNNs) to classify diverse tissue
types from whole slide microscope images accurately. Consequently, enhancing
the accuracy of tissue class decomposition is critical to amplifying the
prognostic potential of imaging-based biomarkers. This study introduces a
hybrid Deep and ensemble machine learning model that surpassed all preceding
solutions for this classification task. Our model achieved 96.74% accuracy on
the external test set and 99.89% on the internal test set. Recognizing the
potential of these models in advancing the task, we have made them publicly
available for further research and development.

We provide an overview of how GNN and model explainability techniques have been applied on fMRI datasets for disorder prediction tasks.
We find that while most studies have performant models, salient features highlighted in these studies vary greatly across studies on the same disorder.
We suggest establishing new standards that are based on objective evaluation metrics to determine the robustness of these potential biomarkers.

We have trained two models, so-called nuclei- and membrane-aware segmentation models, which, once successfully validated, have revealed to be a promising method to segment nuclei instances in IHC-stained images.
