Hybrid Relative Attributes Based on Sparse Coding for Zero-Shot Image Classification
Algorithm 2
Zero-shot image classification based on SC-HRA.
Input: the attribute ranking scores of the training and testing samples | Output: the label of the testing sample | Building of the training models; | Calculate mean value and covariance matrix based on of training sample, | obtain | Building of the testing models; | If is satisfied, then the mean value of model is | , and the covariance matrix is . | If is satisfied, then the mean value of model is , and | the covariance matrix is . | If is satisfied, then the mean value of model is , and | the covariance matrix is . | Testing; | By calculating the attribute ranking score of the testing sample, the class label is | determined as |
