Solution Approach 1:

The patent segments the convolutional layer into two separate operations: depthwise convolution (spatial filtering) and pointwise convolution (channel mixing). This segmentation allows each operation to be optimized independently, reducing overall computational load while maintaining the functional capabilities of the original convolutional layer for accurate inference

Solution Approach 1:

The patent introduces a dynamic parameter transformation model that can adaptively adjust the transformation parameters based on the specific layer characteristics and resource constraints. This dynamic approach allows the model to maintain optimal inference accuracy while achieving lightweighting, as the transformation can be tailored to preserve critical features in each layer
