1. A system for detecting a faulty sensor in a multi-sensor monitor, the system comprising: a partitioning module 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; a training module for 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; an estimating module for obtaining an estimated sensor value corresponding to each sensor of the multi-sensor monitor using the model; and a fault-determining module for testing at least one sensor combination if at least one sensor value is not within the range of acceptable sensor values, the at least one sensor combination including at least one sensor whose estimated sensor value is not within the range of acceptable values.
