New paper accepted at MICCAI LABELS 2020

Our paper entitled “Semi-Weakly Supervised Learning for Prostate Cancer Image Classification with Teacher-Student Deep Convolutional Networks“, by S. Otálora, N. Marini, M. Atzori and H. Müller has been accepted for publication at the MICCAI workshop LABELS 2020: Large-scale Annotation of Biomedical data and Expert Label Synthesis.

In this paper, we propose a teacher-student approach for training data-hungry models using images automatically annotated by a deep CNN model. Our results in the challenging task of automatic grading of prostate cancer images show that using this approach is significantly better than training the CNN with the small set of ground-truth annotations. It opens the possibility to use vast amounts of non-annotated data.

Paper accepted at MICCAI 2020

Our paper entitled “Multimodal Latent Semantic Alignment for Automated Prostate Tissue Classification and Retrieval” has been accepted for presentation at MICCAI 2020.

In this work, our group collaborated with the MindLAB group (Universidad Nacional de Colombia) to develop an information fusion method for the automatic analysis of prostate cancer images.

More details can be found in the paper.

Paper accepted in Computers in Biology and Medicine

Our new paper entitled “Concept attribution: Explaining CNN decisions to physicians” by Mara Graziani, Vincent Andrearczyk, Stephane Marchand-Maillet and Henning Müller has been accepted for publication in Computers in Biology and Medicine.

Feature attribution techniques explain Convolution Neural Networks (CNNs) in terms of the input pixels. The abstraction to higher level impacting factors, however, can be difficult when only a pixel-based analysis is performed. In this paper, we generate explanations in terms of prognostic factors for breast cancer, such as nuclei pleomorphism.

Official start of the HECKTOR challenge

We are happy to announce the official start of the HECKTOR challenge (at MICCAI 2020) with the release of the training data. It comprises 201 cases of Head and Neck tumors with manual annotations on PET-CT images for segmentation of primary Gross Tumor Volumes.

The data can be downloaded from the aicrowd page.

A code for preprocessing the data, a baseline CNN and an example evaluation can be found on our github repository.

Video Tutorial on Interpretable Machine Learning

How do you interpret your machine learning models?
Our third-year Ph.D. student Mara Graziani gave a virtual tutorial at IBM Research Zurich about applying interpretability techniques.
The recording was kindly shared on the Youtube channel of our school.

This talk provides an overview of the main interpretability approaches and a glimpse of our future research directions.

Paper accepted at BioRob 2020

Our paper on the “Effect of movement type on the classification of electromyography data for the control of dexterous prosthetic hands” by Manfredo Atzori, Elisa Rosanda, Giorgio Pajardi, Franco Bassetto and Henning Müller has been accepted for presentation at the IEEE RAS/EMBS International Conference on Biomedical Robotics and Biomechatronics (BioRob 2020). The conference is currently planned to take place 29 Nov. – 2 Dec. 2020, in New York City, NY, USA.
