Model-Based Deep Learning: On the Intersection of Deep Learning and Optimization

Abstract: Decision making algorithms are used in a multitude of different applications. Conventional approaches for designing decision algorithms employ principled and simplified modelling, based on which one can determine decisions via tractable optimization. More recently, deep learning approaches that use highly parametric architectures tuned from data without relying on mathematical models, are becoming increasingly popular. Model-based optimization and data-centric deep learning are often considered to be distinct … Show more

“…In model-based deep learning, DNN architectures are designed that are inspired by model-based algorithms tailored to the particular problem of interest [19]. In the context of deep receivers, the dominant model-based deep learning methodologies are deep unfolding and DNN-aided inference, which are illustrated in Fig.…”

“…For each of these AI pillars, we survey candidate approaches for facilitating the operation of the deep receivers. (i) We first discuss how to design light-weight trainable architectures via model-based deep learning [19]. This methodology hinges on the principled incorporation of model-based processing, obtained from domain knowledge on optimized communication algorithms, within AI architectures.…”

“…A second set of works focused on integrating deep learning into the basic decoder design, as a form of model-based deep learning [7]. In particular, the deep unfolding methodology was utilized in [8] to leverage data to improve BP decoding with a fixed number of iterations, and was adapted to BPbased polar decoding in [9].…”
