System and method for detecting and excluding outlier sensors in sensor-based monitoring

A method of detecting a faulty sensor in a multi-sensor monitor, the method comprising the steps of:

• partitioning a plurality of sensor values generated by the multi-sensor monitor into two sets, the sets defining a training set comprising a portion of the plurality of sensor values and a validation set comprising another portion of the plurality of sensor values;
• training a model using the sensor values belonging to the training set and applying the model to each sensor value belonging to the validation set so as to determine a range of acceptable sensor values;
• obtaining an estimated sensor value corresponding to each sensor of the multi-sensor monitor using the model;
• and
• if at least one estimated sensor value corresponding to one of the sensors is not within the range of acceptable sensor values, testing at least one sensor combination comprising at least one sensor whose estimated sensor value is not within the range of acceptable values so as to determine whether the combination includes a faulty sensor.

A computer readable storage medium for use with multi-sensor monitor, the storage medium comprising computer instructions for:

• partitioning a plurality of sensor values generated by the multi-sensor monitor into two sets, the sets defining a training set comprising a portion of the plurality of sensor values and a validation set comprising another portion of the plurality of sensor values;
• training a model using the sensor values belonging to the training set and applying the model to each sensor value belonging to the validation set so as to determine a range of acceptable sensor values;
• obtaining an estimated sensor value corresponding to each sensor of the multi-sensor monitor using the model;
• and
• if at least one estimated sensor value corresponding to one of the sensors is not within the range of acceptable sensor values, testing at least one sensor combination comprising at least one sensor whose estimated sensor value is not within the range of acceptable values so as to determine whether the combination includes a faulty sensor.
