Sensor Physical Interpretation, Signal and Artificial Intelligence Processing (SPISAIP) is an overarching field of research focusing on the physical and mathematical foundations and practical applications of sensors, interpretation, signal processing and artificial intelligence algorithms that learn, reason and act. It bridges the boundary between theory and application, developing novel theoretically inspired methodologies targeting both longstanding and emergent sensor-based applications.

The core of SPISAIP lies in its use and proposed physical meaning in sensors, nonlinear and non-Gaussian signal processing methodologies combined with convex and non-convex optimization, and sensor-based machine learning/deep learning neural networks. SPISAIP encompasses new theoretical frameworks for interpreting sensing in statistical signal processing (e.g. hidden markov model, latent component analysis, tensor factorization, Bayesian methods) coupled with information theoretic learning, and novel developments in these areas specialised to the processing of a variety of modalities including audio, bio-signals, electromagnetic thermal multi-physics signals, images, multispectral, and video among others. In recent years, many sensor design and signal processing algorithms have incorporated some form of intelligence as part of its framework in solving a problem. These algorithms have the capacity to generalize and discover knowledge for themselves and learning to learn new information whenever unseen sensor data is captured.

The focus of the Special Issue will be on a broad range of sensors, physical interpretation, signal and artificial intelligence processing involving the introduction and development of new advanced theoretical and practical algorithms. We welcome both original research and review articles on these topics.
