1 dzień temu · Minimum spanning trees (MSTs) provide a convenient representation of datasets in numerous pattern recognition activities. Moreover, they are relatively fast to compute. In this paper, we quantify the extent to which they are meaningful in low-dimensional partitional data clustering tasks. By identifying the upper bounds for the agreement between the best (oracle) algorithm and the expert ...
3 dni temu · Therefore, the Euclidean distance loses its discriminatory power, impacting the effectiveness of learning algorithms because distances between instances become less informative . In this paper, we hypothesize that the use of fractional norms, norm-p, can alleviate the effect of the high dimensionality in a well-known data-level solution.

3 dni temu · Abstract. Unimodality of the normalized coeficients of the characteristic polynomial of distance matrices of trees are known and bounds on the location of its peak (the largest coeficient) are also known. Recently, an extension of these results to distance matrices of block graphs was given.
