Detection and quantification of temperature sensor drift using probabilistic neural networks

作者:

Highlights:

• New machine learning method for detection of long-term temperature sensor drift.

• New anomaly detection method based on the trinomial distribution.

• Data-driven prediction of temperature in concrete structures is greatly improved.

• The method was successfully tested on 7-years data of a real structure.
