Query: A Novel Multiple Classifier Generation and Combination Framework Based
  on Fuzzy Clustering and Individualized Ensemble Construction   Multiple classifier system (MCS) has become a successful alternative for
improving classification performance. However, studies have shown inconsistent
results for different MCSs, and it is often difficult to predict which MCS
algorithm works the best on a particular problem. We believe that the two
crucial steps of MCS - base classifier generation and multiple classifier
combination, need to be designed coordinately to produce robust results.
  In this work, we show that for different testing instances, better
classifiers may be trained from different subdomains of training instances
including, for example, neighboring instances of the testing instance, or even
instances far away from the testing instance. To utilize this intuition, we
propose Individualized Classifier Ensemble (ICE). ICE groups training data into
overlapping clusters, builds a classifier for each cluster, and then associates
each training instance to the top-performing models while taking into account
model types and frequency. In testing, ICE finds the k most similar training
instances for a testing instance, then predicts class label of the testing
instance by averaging the prediction from models associated with these training
instances.
  Evaluation results on 49 benchmarks show that ICE has a stable improvement on
a significant proportion of datasets over existing MCS methods. ICE provides a
novel choice of utilizing internal patterns among instances to improve
classification, and can be easily combined with various classification models
and applied to many application domains.
