- Abstract summary: An online machine-learning based uncalibration detector for temperature, humidity and pressure sensors was developed.
The solution integrates an Artificial Neural Network as main component which learns from the behavior of the sensors under calibrated conditions.
The obtained results show that the proposed solution is able to detect uncalibrations for deviation values of 0.25 degrees, 1% RH and 1.5 Pa, respectively.

- Abstract: Nowadays, sensors play a major role in several contexts like science,
industry and daily life which benefit of their use. However, the retrieved
information must be reliable. Anomalies in the behavior of sensors can give
rise to critical consequences such as ruining a scientific project or
jeopardizing the quality of the production in industrial production lines. One
of the more subtle kind of anomalies are uncalibrations. An uncalibration is
said to take place when the sensor is not adjusted or standardized by
calibration according to a ground truth value. In this work, an online
machine-learning based uncalibration detector for temperature, humidity and
pressure sensors was developed. This solution integrates an Artificial Neural
Network as main component which learns from the behavior of the sensors under
calibrated conditions. Then, after trained and deployed, it detects
uncalibrations once they take place. The obtained results show that the
proposed solution is able to detect uncalibrations for deviation values of 0.25
degrees, 1% RH and 1.5 Pa, respectively. This solution can be adapted to
different contexts by means of transfer learning, whose application allows for
the addition of new sensors, the deployment into new environments and the
retraining of the model with minimum amounts of data.

It is challenging to place sensors in a way that maximises the informativeness of their measurements, particularly in remote regions like Antarctica.
Probabilistic machine learning models can suggest informative sensor placements by finding sites that maximally reduce prediction uncertainty.
This paper proposes using a convolutional Gaussian neural process (ConvGNP) to address these issues.

Diagnosis on Multivariate Sensor Data [69.25738064847175]
It is necessary to consider the behavior of the signals in each sensor separately, to take into account their correlation and hidden relationships with each other.
The graph nodes can be represented as data from the different sensors, and the edges can display the influence of these data on each other.
It was proposed to construct a graph during the training of graph neural network. This allows to train models on data where the dependencies between the sensors are not known in advance.
