A puzzle of two unreliable sensors (wordpress.com)
Suppose you are trying to measure a value P and you have two unreliable sensors. Sensor A returns 0.5P + 0.5U, where U is uniform random noise over the same domain as P. Sensor B will return either P or U with 50% likelihood. In other words, sensor A is a noisy measurement of your variable, and B is sometimes the correct value and sometimes pure noise.
