As long as the parameter vector is decided, the posterior probability for assigning a data point to a cluster can be easily calculated with Bayes’s theorem. 3 Neural Networks-Based Clustering In competitive neural networks, active neurons reinforce their neighborhood within certain regions, while suppressing the activities of other neurons (socalled on-center/off-surround competition). Typical examples include Learning Vector Quantization (LVQ) and Self-Organizing Feature Maps (SOFM) [48, 49]. Intrinsically, LVQ performs supervised learning, and is not categorized as a clustering algorithm [49, 61].

We present here two algorithms. The first algorithm approximates the function by piecewise polynomials. The algorithm generates a partition of the complicated domain to a small number of less complicated subdomains, where low-degree polynomial approximation is good enough. The partition is a binary space partition (BSP), driven by the geometry of the domain and is encoded with a small budget. This algorithm is used in the compression method of [5, 6]. The second algorithm is based on mapping a complicated ” 20 N.
