Data mining in soft computing framework: a survey
The present article provides a survey of the available literature on data mining using soft computing. A categorization has been provided based on the different soft computing tools and their hybridizations used, the data mining function implemented, and the preference criterion selected by the model. The utility of the different soft computing methodologies is highlighted. Generally fuzzy sets are suitable for handling the issues related to understandability of patterns, incomplete/noisy data, mixed media information and human interaction, and can provide approximate solutions faster. Neural networks are nonparametric, robust, and exhibit good learning and generalization capabilities in data-rich environments. Genetic algorithms provide efficient search algorithms to select a model, from mixed media data, based on some preference criterion/objective function. Rough sets are suitable for handling different types of uncertainty in data. Some challenges to data mining and the application of soft computing methodologies are indicated. An extensive bibliography is also included
GBSVM: Granular-ball Support Vector Machine
GBSVM (Granular-ball Support Vector Machine) is an important attempt to use
the coarse granularity of a granular-ball as the input to construct a
classifier instead of a data point. It is the first classifier whose input
contains no points, i.e., , in the history of machine learning. However,
on the one hand, its dual model is not derived, and the algorithm has not been
implemented and can not be applied. On the other hand, there are some errors in
its existing model. To address these problems, this paper has fixed the errors
of the original model of GBSVM, and derived its dual model. Furthermore, an
algorithm is designed using particle swarm optimization algorithm to solve the
dual model. The experimental results on the UCI benchmark datasets demonstrate
that GBSVM has good robustness and efficiency
