Paradigm framing
The paradigm is automated interictal epileptiform discharge (IED) detection in electroencephalography (EEG) using artificial intelligence. The current model accepts that deep learning is a highly effective method but notes limitations due to class imbalance in datasets and a focus on metrics that don’t directly translate to clinical utility.
Highlights
This preprint resides firmly within the normal science stage. It focuses on puzzle-solving within the accepted paradigm of using AI for IED detection. The authors build upon existing work by trying to improve model precision by addressing two problems:
1. Class imbalance in datasets, which they address with data augmentation using a diffusion probabilistic model.
2. Optimization for clinically relevant metrics like AUPRC instead of only sensitivity and specificity.
The preprint does not propose a radical shift in approach or challenge the underlying assumptions of the paradigm. Instead, it refines existing techniques by introducing a new augmentation method and shifting the optimization strategy for increased precision. This precisely characterizes puzzle-solving activity during normal science, aiming for incremental progress within the established framework.
