Information theory, first introduced as a mathematical theory of communication, paved the way for existence proofs in channel and source coding, where instead of searching for an exact structure of a successful code, one can carry out the easier task of finding a family of codes containing successful ones. This simple approach enabled a hierarchical design, where we can carry out research on overly complex tasks while still having open problems about the underlying building blocks. In this talk, we will provide examples for such complex tasks where progress has been made thanks to this hierarchical vision. Interestingly, with state of the art deep learning algorithms, the rationale of finding a large family of functions containing correct ones, is also the driving force. Further, with empirical data-driven research, all we can hope for is a proof-of-concept; in other words, an “existence” proof. This inspires us to propose a hierarchical framework for employing deep learning in wireless communication systems. The lowest level of the hierarchy consists of source identification tasks that facilitate identifying transmission origins for a given received signal. Given accurate source identification, analyzing and predicting peer behavior becomes feasible. Finally, spectrum/context understanding tasks like scenario classification and recognizing the behavior of peer networks can take place by building on lower-level capabilities. Our discussion is aided by concrete preliminary results, datasets, and lessons learned from Purdue’s participation in the DARPA Spectrum Collaboration Challenge (SC2). In summary, we will discuss in this talk concrete examples at the top of the hierarchical approach for using information theory for wireless communication networks, and concrete examples at the bottom of the hierarchical approach for using deep learning for the same overarching task, since the latter is the less mature area of research.
