COMPUTATION ACCURACY CAN be traded off to
achieve better performance and/or energy efficiency.
The techniques to achieve this tradeoff fall
under the umbrella of approximate computing.
Algorithm-specific approximation has been used in
many different domains such as machine learning,
image processing, and video processing. For example,
a consumer can tolerate occasional dropped
frames or a small loss in resolution during video
playback, especially when this allows video playback
to occur seamlessly.
