Feature space partition: a local–global approach for classification
Abstract We propose a local–global classification scheme in which the feature space is, in a first phase, segmented by an unsupervised algorithm allowing, in a second phase, the application of distinct classification methods in each of the generated sub-regions. The proposed segmentation process int...

| 520 | |a Abstract We propose a local–global classification scheme in which the feature space is, in a first phase, segmented by an unsupervised algorithm allowing, in a second phase, the application of distinct classification methods in each of the generated sub-regions. The proposed segmentation process intentionally produces difficult-to-classify and easy-to-classify sub-regions. Consequently, it is possible to outcome, besides of the classification labels, a measure of confidence for these labels. In almost homogeneous regions, one may be well-nigh sure of the classification result. The algorithm has a built-in stopping criterion to avoid over dividing the space, what would lead to overfitting. The Cauchy–Schwarz divergence is used as a measure of homogeneity in each partition. The proposed algorithm has shown very nice results when compared with 52 prototype selection algorithms. It also brings in the advantage of priory unveiling areas of the feature space where one should expect more (or less) difficult in classifying. | ||

Abstract We propose a local–global classification scheme in which the feature space is, in a first phase, segmented by an unsupervised algorithm allowing, in a second phase, the application of distinct classification methods in each of the generated sub-regions. The proposed segmentation process intentionally produces difficult-to-classify and easy-to-classify sub-regions. Consequently, it is possible to outcome, besides of the classification labels, a measure of confidence for these labels. In almost homogeneous regions, one may be well-nigh sure of the classification result. The algorithm has a built-in stopping criterion to avoid over dividing the space, what would lead to overfitting. The Cauchy–Schwarz divergence is used as a measure of homogeneity in each partition. The proposed algorithm has shown very nice results when compared with 52 prototype selection algorithms. It also brings in the advantage of priory unveiling areas of the feature space where one should expect more (or less) difficult in classifying.

The proposed segmentation process intentionally produces difficult-to-classify and easy-to-classify sub-regions. Consequently, it is possible to outcome, besides of the classification labels, a measure of confidence for these labels. In almost homogeneous regions, one may be well-nigh sure of the classification result. The algorithm has a built-in stopping criterion to avoid over dividing the space, what would lead to overfitting. The Cauchy–Schwarz divergence is used as a measure of homogeneity in each partition. The proposed algorithm has shown very nice results when compared with 52 prototype selection algorithms. It also brings in the advantage of priory unveiling areas of the feature space where one should expect more (or less) difficult in classifying.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Local–global</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Clustering</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Prototype selection</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cauchy–Schwarz</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pedreira, C.

Feature space partition: a local–global approach for classification |
| abstract |
Abstract We propose a local–global classification scheme in which the feature space is, in a first phase, segmented by an unsupervised algorithm allowing, in a second phase, the application of distinct classification methods in each of the generated sub-regions. The proposed segmentation process intentionally produces difficult-to-classify and easy-to-classify sub-regions. Consequently, it is possible to outcome, besides of the classification labels, a measure of confidence for these labels. In almost homogeneous regions, one may be well-nigh sure of the classification result. The algorithm has a built-in stopping criterion to avoid over dividing the space, what would lead to overfitting. The Cauchy–Schwarz divergence is used as a measure of homogeneity in each partition. The proposed algorithm has shown very nice results when compared with 52 prototype selection algorithms. It also brings in the advantage of priory unveiling areas of the feature space where one should expect more (or less) difficult in classifying. © The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature 2022.
