There is a Baysean implantation of this approach on the marketplace as a rule template. Bayesian Sensors - Activation Rule [4.0.0;5.0.0). There’s a MainUI widget to help adjust the weights and such without changing the rule. Bayesian Sensors - Details Widget [4.0.0;5.0.0). Full documentation can be found at Bayesian Sensors in OH4.
The original implementation in Jython can be found at Design Pattern: Bayesian Sensor Aggregation.
