Weboriginal input data vector. As it is a kind of distortion cod-ing, it requires the codebook to represent the various inputs well, like an overcomplete dictionary. Vector quantization can be considered as discrete representation learning; that is, the representation coefficient is a one-hot vector. Many WebThe coefficients R 1 (r out, r in) are the impulse responses between each input focusing point r in and each output imaging point r out. In other words, once reshaped in 2D, each …
