This paper investigates the effects of collaborative filtering on the classification of corrupted digit images. Several experiments were carried out using the MNIST digit dataset by applying a corruption model to the original images, two reconstruction algorithms, and an SVM classifier to measure classification accuracy at each stage of processing. The results demonstrate that collaborative fil...

INTRODUCTION There have been fewer than 150 cases of Bizarre Parosteal Osteochondromatous proliferation (Nora Lesions) reported in the literature to date and no significant reports on angular deformities caused by this lesion. Nora's lesion can easily be misdiagnosed as osteochondroma or chondrosarcoma and therefore inappropriately managed. Although this condition classically appears in the sec...
