Query: Partial Weight Adaptation for Robust DNN Inference   Mainstream video analytics uses a pre-trained DNN model with an assumption
that inference input and training data follow the same probability
distribution. However, this assumption does not always hold in the wild:
autonomous vehicles may capture video with varying brightness; unstable
wireless bandwidth calls for adaptive bitrate streaming of video; and,
inference servers may serve inputs from heterogeneous IoT devices/cameras. In
such situations, the level of input distortion changes rapidly, thus reshaping
the probability distribution of the input.
  We present GearNN, an adaptive inference architecture that accommodates
heterogeneous DNN inputs. GearNN employs an optimization algorithm to identify
a small set of "distortion-sensitive" DNN parameters, given a memory budget.
Based on the distortion level of the input, GearNN then adapts only the
distortion-sensitive parameters, while reusing the rest of constant parameters
across all input qualities. In our evaluation of DNN inference with dynamic
input distortions, GearNN improves the accuracy (mIoU) by an average of 18.12%
over a DNN trained with the undistorted dataset and 4.84% over stability
training from Google, with only 1.8% extra memory overhead.
