Example text

See Figures 4(b) and 5(a) for examples. Different viewers may deduce different numbers of clusters from such poor-quality images, or worse, not be able to estimate c at all. This raises the question of whether we can transform D into a new form D so that the VAT image of D is clearer and more informative about the cluster structure. iVAT and aVAT: Enhanced Visual Analysis 19 In [12], SpecVAT combines VAT with graph embedding [19,20] to solve this problem. SpecVAT first embeds the data into a k-dimensional subspace spanned by the eigenvectors of the normalized Laplacian matrix and then re-computes a new pairwise dissimilarity matrix in the embedding subspace as the input of the VAT algorithm.

If the improvement value is positive, reassign v to Aj immediately, adjust the values of R(Aj ) and R(Ai ), and set halt ← FALSE. Fig. 1. A pseudocode description of the basic GlobalRSC variant During each round of the batch phase, building the inverted neighbor sets requires that the values of K(σ 2 + μ2 ) integer variables be copied. Recalculating R for the tentative reassignment of item v from cluster Ai to cluster Aj requires time proportional to |Ai | + |Aj | + 2|Iv | when using the inverted neighbor lists.
