This booklet relies at the author's adventure with calculations concerning polynomial splines. It offers these elements of the speculation that are particularly worthwhile in calculations and stresses the illustration of splines as linear mixtures of B-splines. After chapters summarizing polynomial approximation, a rigorous dialogue of easy spline concept is given concerning linear, cubic and parabolic splines. The computational dealing with of piecewise polynomial capabilities (of one variable) of arbitrary order is the topic of chapters VII and VIII, whereas chapters IX, X, and XI are dedicated to B-splines. The distances from splines with fastened and with variable knots is mentioned in bankruptcy XII. the remainder 5 chapters hindrance particular approximation tools, interpolation, smoothing and least-squares approximation, the answer of a standard differential equation by way of collocation, curve becoming, and floor becoming. the current textual content model differs from the unique in different respects. The e-book is now typeset (in simple TeX), the Fortran courses now utilize Fortran seventy seven gains. The figures were redrawn by way of Matlab, a number of mistakes were corrected, and plenty of extra formal statements were supplied with proofs. additional, all formal statements and equations were numbered via an analogous numbering approach, to assist you to locate any specific merchandise. a massive swap has occured in Chapters IX-XI the place the B-spline idea is now constructed without delay from the recurrence family with out recourse to divided changes. This has introduced in knot insertion as a robust device for delivering basic proofs in regards to the shape-preserving houses of the B-spline sequence.

From the Is values, it can be seen that although clusters C2 and C2’ are considered as similar there is a noticeable movement in the cluster. As such the data analyst can focus attention on this cluster to identify the reason for such a change. 5 Conclusion This paper described a method of identifying change in the structure of the clusters within a data set. The need and importance of identifying such change in data was discussed and the advantages and limitations of using SOM based techniques for such change monitoring was highlighted.

The amount of adaptation (learning rate) is also reduced exponentially over the iterations. Even within the neighbourhood weights which are closer to the winner are adapted more than those further away. The weight adaptation can be described by: wj (k + 1) = wj (k), wj (k) + LR(k) × (xk − wj (k)), j ∈ Nk+1 j ∈ Nk+1 where the learning rate LR(k), k ∈ N is a sequence of positive parameters converging to 0 as k → ∞. wj (k), wj (k + 1) are the weight vectors of the the node j, before and after the adaptation and Nk+1 is the neighbourhood of the winning neuron at (k + 1)th iteration.

Growing Phase a) Present input to the network. 3 Monitoring Shift and Movement in Data using Dynamic Feature Maps 31 b) Determine the weight vector that is closest to the input vector mapped to the current feature map (winner), using Euclidean distance (similar to the SOM). This step can be summarised as: Find q such that |v − wq | ≤ |v − wq | ∀q ∈ N where v, w are the input and weight vectors respectively, q is the position vector for nodes and N is the set of natural numbers.
