Making image to class distance comparable

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Image classification is to classify the image into predefined image categories. The image to class distance(I2CD), with simple formulation, can tackle the intra-class variation and show the state of the art results in several datasets. This paper focuses on the performance of I2CD on imbalanced training dataset which has not been catched much attention by I2CD researchers. Under the naive bayes assumption, when the dataset is imbalanced, I2CD is not comparable. We propose Random Sampling I2CD to tackle the imbalanced problem, and provide an efficient approximation method to reduce the test time complexity. Experimental results show that PRSI2CD outperforms the original I2CD in imbalanced setting.
