MixUp-MIL: Novel Data Augmentation for Multiple Instance Learning and a Study on Thyroid Cancer Diagnosis
Multiple instance learning exhibits a powerful approach for whole slide
image-based diagnosis in the absence of pixel- or patch-level annotations. In
spite of the huge size of hole slide images, the number of individual slides is
often rather small, leading to a small number of labeled samples. To improve
training, we propose and investigate different data augmentation strategies for
multiple instance learning based on the idea of linear interpolations of
feature vectors (known as MixUp). Based on state-of-the-art multiple instance
learning architectures and two thyroid cancer data sets, an exhaustive study is
conducted considering a range of common data augmentation strategies. Whereas a
strategy based on to the original MixUp approach showed decreases in accuracy,
the use of a novel intra-slide interpolation method led to consistent increases
in accuracy.Comment: MICCAI'23, https://gitlab.com/mgadermayr/mixupmi
