چکیده
A novel class of Learning Vector Quantizers LVQs based on multivariate order statistics is proposed in order to overcome the drawback that the estima tors for obtaining the reference vectors in LVQ do not have robustness either against erroneous choices for the winner vector or against the outliers that may exist in vector valued observations The per formance of the proposed variants of LVQ is demon strated by experiments In the case of marginal me dian LVQ its asymptotic properties are derived as well

Order Statistics Learning Vector Quantizer [Correspondence] - Image Processing, IEEE Transactions on
In this correspondence, we propose a novel class of learning vector quantizers (LVQ’s) based on multivariate data ordering principles. A special case of the novel LVQ class is the median LVQ, which uses either the marginal median or the vector median as a multivariate estimator of location. The performance of the proposed marginal median LVQ in color image quantization is demonstrated by experi...
متن کاملRecursive partitioning to reduce distortion
Adaptive partitioning of a multidimensional feature space plays a fundamental role in the design of data-compression schemes. Most partition-based design methods operate in an iterative fashion, seeking to reduce distortion at each stage of their operation by implementing a linear split of a selected cell. The operation and eventual outcome of such methods is easily described in terms of binary...
متن کاملApproximation of the Gradient of the Error Probability for Vector Quantizers
Vector Quantizers (VQ) can be exploited for classification. In particular the gradient of the error probability performed by a VQ with respect to the position of its code vectors can be formally derived, hence the optimum VQ can be theoretically found. Unfortunately, this equation is of limited use in practice, since it relies on the knowledge of the class conditional probability distributions....
متن کاملRobust vector quantization by competitive learning
Competitive neural networks can be used to e ciently quantize image and video data. We discuss a novel class of vector quantizers which perform noise robust data compression. The vector quantizers are trained to simultaneously compensate channel noise and code vector elimination noise. The training algorithm to estimate code vectors is derived by the maximum entropy principle in the spirit of d...
