Special Issue Information

The pervasive use of sensors, portable or worn by the user and incorporated in the surrounding environment, generates increasingly large and diversified data flows, big sensor data, which are ill suited to be processed using only traditional signal processing techniques. The application of machine learning in the signal and image processing area has proven very useful in addressing this growing complexity. The systematic use of machine learning and artificial intelligence, with particular focus on the emerging areas of autoML (automatic machine learning) and deep learning (deep artificial neural networks), is receiving much attention in industry and academia for modeling, design, and development of smart technological solutions.

In this context, intelligent sensing and advanced signal processing techniques, well suited to treat a large amount of multi-sensor and multi-channel data, generated at a constant rate by the ever-growing number of permanently connected smart devices (according to the Internet of Things paradigm), are the main focus of this Special Issue, aiming at the same time to highlight their great impact in different smart-x sectors, such as smart home, smart building, smart city, smart healthcare, smart transportation, and smart industry, just to name a few.

The purpose of this Special Issue is to reflect the most recent advances, present representative applications, and define future research directions related to the application of AI for intelligent sensing and advanced signal processing in smart-x technology, through machine learning, deep learning, computational intelligence, cognitive computing, and other emerging areas of AI. Prospective authors are invited to submit original and high-quality papers that are related, but not limited, to one or more of the following topics:

  • Machine learning techniques for multi-sensor time series analysis, classification, clustering, and forecasting in smart-x applications;
  • Pattern recognition and predictions using multi-sensor time series data;
  • Multi-sensor fusion strategies and their application in smart-x areas;
  • Synthetic long-term multi-sensor time series simulation and generation;
  • Change point detection in multi-sensor time series data;
  • Intelligent sensing-based decision support system for diagnosis, maintenance planning, and operation scheduling in smart-x applications;
  • Machine learning-based critical event detection, diagnosis, and prediction using multi-sensor time series signals;
  • Long-term multi-sensor time series signal processing.

Inertial-sensor-based attitude estimation is a crucial technology in various applications, from human motion tracking to autonomous aerial and ground vehicles. Application scenarios differ in characteristics of the performed motion, presence of disturbances, and environmental conditions. Since state-of-the-art attitude estimators do not generalize well over these characteristics, their parameters must be tuned for the individual motion characteristics and circumstances. We propose RIANN, a ready-to-use, neural network-based, parameter-free, real-time-capable inertial attitude estimator, which generalizes well across different motion dynamics, environments, and sampling rates, without the need for application-specific adaptations. We gather six publicly available datasets of which we exploit two datasets for the method development and the training, and we use four datasets for evaluation of the trained estimator in three different test scenarios with varying practical relevance. Results show that RIANN outperforms state-of-the-art attitude estimation filters in the sense that it generalizes much better across a variety of motions and conditions in different applications, with different sensor hardware and different sampling frequencies. This is true even if the filters are tuned on each individual test dataset, whereas RIANN was trained on completely separate data and has never seen any of these test datasets. RIANN can be applied directly without adaptations or training and is therefore expected to enable plug-and-play solutions in numerous applications, especially when accuracy is crucial but no ground-truth data is available for tuning or when motion and disturbance characteristics are uncertain. We made RIANN publicly available. Full article
