Image classification using local linear regression
In the past several decades, classifier design has attracted much attention. Inspired by the
locality preserving idea of manifold learning, here we give a local linear regression (LLR)
classifier. The proposed classifier consists of three steps: first, search k nearest neighbors of
a pointed sample from each special class, respectively; second, reconstruct the pointed
sample using the k nearest neighbors from each special class, respectively; and third,
classify the test sample according to the minimum reconstruction error. The experimental …

Abstract
In the past several decades, classifier design has attracted much attention. Inspired by the locality preserving idea of manifold learning, here we give a local linear regression (LLR) classifier. The proposed classifier consists of three steps: first, search k nearest neighbors of a pointed sample from each special class, respectively; second, reconstruct the pointed sample using the k nearest neighbors from each special class, respectively; and third, classify the test sample according to the minimum reconstruction error. The experimental results on the ETH80 database, the CENPAMI handwritten number database and the FERET face image database demonstrate that LLR works well, leading to promising image classification performance.
