Research Abstract

This is a difficult problem on how to classify the unlabeled data in training data and the test data by few labeled data in the field of machine learning and pattern recognition. Especially, some noise data lie on the training data. We propose a graph-based semi-supervised learning with active contour based on the above problems. The algorithm not only removes the noise data, but also classifies the unlabeled data in training data and the test data. The algorithm is applied in the synthetic data and medical images.
