Smart Alarm- On the performance characteristics of linear, multi-linear and non-linear tensor models for alarm prediction in multi-sensor data.

Abstract: Information and modern computing technology advancements have led to a rise in the importance of maintenance, particularly in areas where a single components failure could have a significant impact on the overall systems performance. Numerous industries, including Alfa Laval, are operating on conditional-based systems that provide warnings only when a machine fails. In the worst instances, pro- longed downtime or machine failure can be costly in terms of money, time, and security [2]. The Alfa Laval company is interested in build- ing a smart alarm system that anticipates alarms and warnings based on sensor readings. For solving these issues, predictive maintenance using machine learning is one of the most effective approach to de- tect the machine condition in advance for maintenance and prevent it from real-time damage or faults. To obtain the best prescient machine learning model, we examined multi-linear and non-linear methods with tensor representation and the linear method as a baseline on real-time multi-sensor time-series datasets to build the smart alarm predictive system to anticipate cautions and warnings. As per the ex- perimental results, we are more certain that the non-linear (Tensor Convolutional Neural Network) method is more ideal than the other methods for the company’s multivariate time series datasets.
