Primary Challenges
Can you explain how you would approach the problem of training a deep learning model to predict future invasive cancer risk using H&E-stained images, ensuring model generalizability across diverse patient datasets?
The candidate was asked to describe their approach to training a deep learning model to predict cancer risk, focusing on handling large H&E-stained images, ensuring generalizability across diverse datasets, and addressing challenges in the process.
The candidate explained their approach of processing gigapixel-sized H&E-stained images by extracting smaller tiles (e.g., 256x256), which are then fed into convolutional neural networks (CNNs) like VGG16, ResNet50, or DenseNet, as well as transformer-based architectures. They integrate clinical-pathological features with imaging data by merging vector data into fully connected layers. Their workflow includes splitting datasets into training, validation, and testing sets, using tenfold cross-validation to select the best model configuration. They validate the model on unknown datasets and involve clinicians and pathologists for external validation. They utilize metrics such as AUC-ROC, sensitivity analysis, and uncertainty analysis to assess performance and emphasize the importance of supervised, semi-supervised, and unsupervised learning approaches to overcome labeling challenges in cancer research.
