However, each of the elements calculated from the training samples are utilized for representation without selection, which can lead to poor ... WebDec 7, 2024 · Recently, collaborative representation-based classification (CRC) and its many variations have been widely applied for various classification tasks in pattern recognition. To further enhance the pattern discrimination of CRC, in this article we propose a novel extension of CRC, entitled discriminative, competitive, and collaborative …
WebIn addition, collaborative representation (CR) is another representation-based model. CR can obtain the analytic solution directly by least squares, that greatly reduces running time in the case of little difference in classification accuracy from SR . The main difference of SR and CR is that SR minimizes l 1-norm but CR minimizes l 2-norm. The ...
