Dynamic time warping is used to obtain time-normalized distances between sequences with different lengths. Good results have been obtained in speaker-independent speech recognition.
It follows an unsupervised learning approach and trained its network through a competitive learning algorithm. Step 3 − Continue step 4-6 for every input vector x. The Kohonen LVQ-I algorithm is summarized in Algorithm 4.2. Download preview PDF. Part of Springer Nature. Learning Vector Quantization (LVQ) has been stud ied to generate optimal reference vectors because of its simple and fast learning al gorithm (Kohonen, 1989; 1995). This method performs a vector quantization (VQ) on the values obtained after processing. 2–7, Espoo, Finland, 1997.
