Industry 4.0 requires for continuous monitoring of processes variables, parameters and working conditions. Measurement systems are a fundamental pillar of industrial process monitoring. Physical and economic constraints are often in contrast with efficiency and cost reduction. The possibility to adopt models, known as soft sensors (SSs), devoted to the estimation of process variables, represents a significant turning point.
SSs for the industry represent an interesting field of applications for machine learning techniques. Advanced methodologies like long short-term memory, stacked autoencoders, convolutional neural networks, reservoir computing, and bio-inspired learning techniques have recently been proposed to improve SSs behavior.
Different aspects still need to be investigated such as SS design for time-variant systems, feature and data selection, outliers detection, big/small datasets, choice of the model class, model validation and maintenance, model interpretability, and transfer learning.
After the success of the Special Session on Soft Sensor for Industry 4.0, implemented at MetroXRAINE 2022, the Special Session is proposed again. The focus is on recent developments and challenges of SS design both from a theoretical perspective and industrial applications.
