Fuente: Wipo "Sensorization" A system includes an interface configured to receive first sensor data from multiple first sensors associated with a monitored system and also includes one or more processors. The one or more processors are configured to provide first input data to a plurality of regression models of a first virtual sensor corresponding to a particular sensor of the monitored system. The first input data is based on the first sensor data. The one or more processors are configured to obtain, from the plurality of regression models, output data based on the input data. The output data from each regression model of the plurality of regression models represents an estimated sensor reading of the particular sensor. The one or more processors are also configured to determine a simulated sensor reading for the particular sensor based on the output data, determine a confidence estimate associated with the simulated sensor reading, or both.
