The framework was developed in a multi-stage Delphi process and is based on the novel concept of a problem fingerprint - a structured representation of the given problem that captures all aspects that are relevant for metric selection, from the domain interest to the properties of the target structure(s), data set and algorithm output.

BI-RADS BERT & Using Section Segmentation to Understand Radiology Reports

1 code implementation14 Oct 2021 Grey Kuling, Dr. Belinda Curpen, Anne L. Martel

In this work, we pre-trained a contextual embedding BERT model using breast radiology reports and developed a classifier that incorporated the embedding with auxiliary global textual features in order to perform section segmentation.

Resource and data efficient self supervised learning

no code implementations3 Sep 2021 Ozan Ciga, Tony Xu, Anne L. Martel

We investigate the utility of pretraining by contrastive self supervised learning on both natural-scene and medical imaging datasets when the unlabeled dataset size is small, or when the diversity within the unlabeled set does not lead to better representations.

Self-supervised driven consistency training for annotation efficient histopathology image analysis

2 code implementations7 Feb 2021 Chetan L. Srinidhi, Seung Wook Kim, Fu-Der Chen, Anne L. Martel

In this work, we overcome this challenge by leveraging both task-agnostic and task-specific unlabeled data based on two novel strategies: i) a self-supervised pretext task that harnesses the underlying multi-resolution contextual cues in histology whole-slide images to learn a powerful supervisory signal for unsupervised representation learning; ii) a new teacher-student semi-supervised consistency paradigm that learns to effectively transfer the pretrained representations to downstream tasks based on prediction consistency with the task-specific un-labeled data.

Overcoming the limitations of patch-based learning to detect cancer in whole slide images

no code implementations1 Dec 2020 Ozan Ciga, Tony Xu, Sharon Nofech-Mozes, Shawna Noy, Fang-I Lu, Anne L. Martel

We apply a binary cancer detection network on post neoadjuvant therapy breast cancer WSIs to find the tumor bed outlining the extent of cancer, a task which requires sensitivity and precision across the whole slide.

Self supervised contrastive learning for digital histopathology

1 code implementation27 Nov 2020 Ozan Ciga, Tony Xu, Anne L. Martel

In this paper, we use a contrastive self-supervised learning method called SimCLR that achieved state-of-the-art results on natural-scene images and apply this method to digital histopathology by collecting and pretraining on 57 histopathology datasets without any labels.

Learning to segment images with classification labels

no code implementations28 Dec 2019 Ozan Ciga, Anne L. Martel

Annotating data for segmentation is generally considered to be more laborious as the annotator has to draw around the boundaries of regions of interest, as opposed to assigning image patches a class label.
