Abstract
This disclosure provides methods, devices, and systems for machine learning. The present implementations more specifically relate to techniques for reducing the computational load of a convolutional neural network (CNN) when processing successive video frames. In some aspects, a machine learning system may cache or store the outputs (also referred to as 'activations') produced by one or more layers of a CNN so that one or more cached activations can be substituted for respective activations that would otherwise be computed by the CNN when processing a subsequent video frame. For example, the machine learning system may compare each video frame with a preceding frame of the video to detect pixels that undergo significant changes between successive frames (also referred to as “motion pixels”). In some aspects, the CNN may only perform neural network operations that involve one or more motion pixels or features derived from a motion pixel.
