Information Theory and Image Coding 2.4.3 Optimum Uniform Quantization Since the number of solution parameters can be rather large for optimum nonuniform quantization, one often seeks a suboptimal solution with far fewer parameters. One such category of solutions is the uniform quantizer, where the ...

We then define quantum operators on the bipartite graph using Szegedy’s quantum walks, which are a quantization of random walks. Derving Bipartite graphs from hypergraphs Proposition 1 Any regular uniform hypergraph HGk,d can be represented usefully by a bipartite graph BGn,m: the vertices V ...

Sampling and quantization Håkan Johansson, in Signal Processing and Machine Learning Theory, 2024 5.3.1 Uniform sampling Discrete-time signals are typically generated through sampling (measurement) of continuous-time signals. Most signal processing applications are based on uniform sampling, which means...
Also, by quantizing the weights, Putra et al., [33] proposed a quantization framework for SNN that helps to reduce memory by about two times corresponding to a decrease in the overall accuracy of about 2 %. Both works aim to quantize the weights of the SNN to save memory with the ...
Non-uniform quantizationWith the popularity of image editing software and technology, it has become very easy to manipulate an image, which has challenged the authenticity and security of digital images. Digital Image Manipulation Forensics (DIMF) has become an important research direction to confirm ...
