Abstract

The implementation of computer vision generally focuses on resolving a problem of one of two types of image data, whether it was natural image datasets or medical image datasets. Self-supervised learning (SSL), as the most recent approach in computer vision, is typically used to solved tasks related only to natural image datasets such as ImageNet, CIFAR-10, and PASCAL. This study focuses on analyzing the involvement of natural images in the SSL implementation when classifying medical images. We used the ResNet50 architecture comparing the results of human embryo image classification using the conventional transfer learning method and SSL methods. We apply three SSL approaches, namely Rotation, Jigsaw Puzzle, and SimCLRv1. The results of our research, with 1226 embryo images divided into three classes, show that the SSL implementations cannot be said to be efficient enough compared to the conventional model produced by ResNet50 with pretrained weight ImageNet. However, when the models were trained using random weight initialization, the Rotation model with an average accuracy of 78.15% and the Jigsaw Puzzle model with an average accuracy of 80.30% are significantly superior to the conventional model with average accuracy is 71.07%. Moreover, related to our embryos dataset, we discuss the differences between the SSL context-context contrastive learning approach and the context instance contrastive learning approach.
