1. A processor-implemented method, comprising:
receiving a video data stream including at least a first frame and a second frame;
extracting first features from the first frame using a teacher neural network;
determining a difference between the first frame and the second frame;
extracting second features from at least the difference between the first frame and the second frame using a student neural network;
generating a feature map for the second frame based on a summation of the first features and the second features; and
generating an inference for at least the second frame of the video data stream based on the generated feature map for the second frame.
