Vector Quantization Semantic Scholar

Vector Quantization Semantic Scholar The density matching property of vector quantization is powerful, especially for identifying the density of large and high dimensioned data. since data points are represented by the index of their closest centroid, commonly occurring data have low error, and rare data high error. Recent studies have employed vector quantization (vq) to enable discrete semantic transmission, yet existing methods neglect channel state information during codebook optimization, leading to suboptimal robustness.

Vector Quantization Semantic Scholar In this paper, we develop a deep learning (dl) enabled vector quantized (vq) semantic communication system for image transmission, named vq deepsc. Specifically, we propose a convolutional neural network (cnn) based transceiver to extract multi scale semantic features of images and introduce multi scale semantic embedding spaces to perform semantic feature quantization, rendering the data compatible with digital communication systems. We introduce a set of advanced theoretically grounded quantization algorithms that enable massive compression for large language models and vector search engines. In this paper, we develop a deep learning (dl) enabled vector quantized (vq) semantic communication system for image transmission, named vq deepsc.

Recent results obtained in waveform coding of speech with vector quantization are reviewed, with vector quantization appearing to be a suitable coding technique which caters to this dual requirement of effective speech coding. The proposed model, called svq, leverages recent advances in unsupervised object centric learning to address this limitation and achieves superior generation performance compared to non semantic vector quantization methods such as vq vae and previous object centric generative models. Most existing semantic communication systems directly map source data to channel symbols, resulting in constellation points that may appear at arbitrary positio. This paper proposes a novel end to end digital semantic communication framework based on multi codebook vector quantization (vq), referred to as esc mvq.
