Latest Patents

Amitava Das holds a patent for a method titled "Variable Dimension Vector Quantization." This method utilizes a single 'universal' codebook to perform variable dimension vector quantization. The technique allows for the sampling of full-dimensioned codevectors in the universal codebook, generating subcodevectors that match the dimension of input data subvectors, which can vary over time. The process involves selecting a subcodevector from the codebook that minimizes distortion when compared to the input data subvector. This subcodevector corresponds to a representative, full-dimensioned codevector in the codebook. The design of the codebook is achieved through inverse sampling of training subvectors, followed by iterative clustering until a stable centroid vector is established.
