1 # Convolution 2 3 **Source:** Probabilistic Robotics 4 5 **Definition:** A convolution is an operation that shifts one function across the results of another, computing the weighted sum of the results to create a third function. 6 7 An example of this is representing the movement of a robot when performing localization. When a robot moves, we can apply a convolution across the previous posterior distribution to make a new prior distribution that takes into account the uncertainty imposed by robot movement.
