In this talk, we first introduce a semi-supervised classification algorithm based on Laplacian support vector machine (SVM) with a quasi-linear kernel. The algorithm consists of two steps. In the first step, it composes a quasi-linear kernel through implementing a piecewise linear model based on neural networks. In the second step, the piecewise linear model is further optimized by a Laplacian SVM algorithm using the quasi-linear kernel function. In both steps, it effectively leverages a small amount of labeled and a large amount of unlabeled data so as to achieve good classification performance. Then we introduce an application of the algorithm to construct a semi-supervised classifier for parasite image classification, by including a semi-supervised feature extractor based on deep CNN using contrastive learning.
