Confusion Graph: Detecting Confusion Communities in Large Scale Image Classification

For deep CNN-based image classification models, we observe that confusions between classes with high visual similarity are much stronger than those where classes are visually dissimilar. With these unbalanced confusions, classes can be organized in communities, which is similar to cliques of people in the social network. Based on this, we propose a graph-based tool named “confusion graph” to qu...

Data Cleaning for Classification Using Misclassification Analysis

In most classification problems, sometimes in order to achieve better results, data cleaning is used as a preprocessing technique. The purpose of data cleaning is to remove noise, inconsistent data and errors in the training data. This should enable the use of a better and representative data set to develop a reliable classification model. In most classification models, unclean data could somet...

Confusion Matrix Stability Bounds for Multiclass Classification

We provide new theoretical results on the generalization properties of learning algorithms for multiclass classification problems. The originality of our work is that we propose to use the confusion matrix of a classifier as a measure of its quality; our contribution is in the line of work which attempts to set up and study the statistical properties of new evaluation measures such as, e.g. ROC...

Robust classification modeling on microarray data using misclassification penalized posterior

MOTIVATION Genome-wide microarray data are often used in challenging classification problems of clinically relevant subtypes of human diseases. However, the identification of a parsimonious robust prediction model that performs consistently well on future independent data has not been successful due to the biased model selection from an extremely large number of candidate models during the clas...

Much of this is too well known to need, or bear, repetition. But the conificting claims and pro posals are now so numerous, and methodological problems loo...
