Abstract: This paper presents an efficient binary search-like algorithm for vector quantization (VQ). The proposed algorithm adopts a tree-structured VQ with overlapped codewords (TSOC) to reduce ...

PCA works by transforming the original data into a new coordinate system through a linear transformation ... This method typically entails data quantization, normalization, and weight calculation. (25 ...

In this letter, we propose a unified algorithmic framework for solving sparse regularization linear inverse problems. Our method combines the principles of ISTA and IRLS to create an element-wise ...
