Compressive Sensing Meets Machine Learning
Ali Gurbuz | firstname.lastname@example.org
Abstract: In this talk, I will introduce several machine learning based projects going on in IMPRESS Lab and present several recent results on compressive learning. Since the revolution of digital age, sensors acquire data in a fixed way independent of the task and how that data can be utilized. Compressive sensing (CS) revised data acquisition by utilizing sparse data models and provided a novel data acquisition and processing method which allows reconstruction of sparse signals with much lower number of measurements than what is implied by the Nyquist rate. CS has created many applications from medical imaging, to radar or wireless communications. However, the data acquisition is still not task driven or adaptive. This talk will introduce learning-based frameworks mimicking compressive sensing structures for modeling and integrating data acquisition and signal processing tasks, such as reconstruction or inference, with learnable network structures. Recent results on machine learning based signal reconstruction and learning optimal set of measurements for a given signal class will be provided. Join me to see how the two main topics in the last decade of signal processing research, compressive sensing and machine learning, come together in a joint framework.
