Two topics will be specifically addressed, namely i) multi-label classification using probabilistic graphical model (PGM) structure learning, and 2) deep learning for ultrasound imaging. First, we will see how several popular loss functions (Hamming loss, 0/1 loss, F-loss) affect the parameter and time complexity of the multi-label learning problem, and how these are lowered when the conditional distribution p(y|x) meets some specific independence constraints, i.e. a decomposition into irreducible label factors [1,2,3]. Second, I will present the problem of plane wave medical ultrasound imaging, which I will formulate as a supervised learning problem. I will present some specificities of the problem which call for original contributions, and show some promising results inspired by the HyperNetwork paradigm .
