This model is used for learning vector representations of words, called "word embeddings". GARCIA-BERNAL Dept. of the form r = S(q −Z) (1) for some constants S and Z. Codebook vectors represent class regions. LVQ can be understood as a special case of an artificial neural network, more precisely, it applies a winner-take-all Hebbian learning-based. of Mathematics Mittweida, Saxonia - Germany 2- University Marburg - ac. Quantization A framework for vector quantization. In conclution, the result of video analysis with duration during 299 second by using LVQ (Learning Vector Quantization) method. For xedrate,theperformanceofvector quantization improves as dimension increases but, unfortunately, the number of codevectors grows exponentially with dimension.
