Title: Logical Signal Processing: a Fourier Analysis of Temporal Logic

Abstract: Temporal logic is a mathematical language for describing the properties of computer and dynamical systems, and has found wide use in the verification and control of cyber-physical systems. It is obtained by adding temporal modalities to classical boolean logic. In this work we seek to re-cast temporal logic and its various uses as "just another signal processing operation", which is essential for the study of Cyber-Physical Systems. Specifically, we ask: What is the frequency content of temporal logic formulas? That is, when we monitor a signal against a formula, which frequency bands of the signal are relevant to the logic, and which can be safely discarded? To answer this question, we focus on monitors that measure the robustness of a signal relative to a specification in Signal Temporal Logic. We prove that robustness monitors can be modeled using Volterra series. We then study the Fourier transforms of these Volterra representations, and provide a method to derive the Fourier transforms of entire formulas. Experiments illustrate these results. Beyond compression, this work enables a common formalism to study both logical and non-logical operations in the frequency domain, which we refer to as Logical Signal Processing. 

Speaker Bio: Houssam Abbas received the Ph.D. in electrical engineering from Arizona State University. From 2006 to 2014, he worked as a CAD engineer in the SoC Verification Group in Intel. In that role, he developed software tools and methods for SoC verification and testing, including formal verification and coverage-based testing, and for the verification of low-power digital designs. In 2015 he joined the ESE department at the University of Pennsylvania as a research postdoc. While at Penn, he co-lead the F1/10 autonomous racing effort which has grown into an international competition. He also developed a semester-long hands-on class to build, program, and race self-driving cars, with all material at f1tenth.org. In January 2019, Houssam joined the School of Electrical Engineering and Computer Science at Oregon State University as an assistant professor.
