In particular, many attempts have been presented to use other image modalities as ancillary information in object detection tasks. Recently, the combined modality was shown to be capable of simultaneous use to produce better classifiers than either modality alone 5, 6, 7. 3 presented a simple experiment to demonstrate use of meta-learning for fine-tuning a medical image dataset and demonstrated better classification performance than the current state-of-the-art method. The authors developed a predictive model based on matching neural network architecture 4, and showed that the model obtained greater effectiveness than vanilla DNNs. 2 used few-shot learning, which is a type of meta-learning method for early diagnosis of glaucoma in fundus images. Several studies have been proposed to apply meta-learning techniques to medical images 2, 3. The task is also known as “learning to learn” and aims to design models that can learn new tasks rapidly. Meta-learning is a recent technique to overcome (i.e., automate) this problem. In addition, the numerous parameters require tuning based on physician assumptions and experience against concrete problems and training datasets, a tedious and resource-intensive task. This leads to performance degradation of DNNs with a relatively large number of parameters, thus requiring a more sophisticated learning algorithm. In particular, protection of patient medical information and unwillingness to share information between hospitals causes difficulty in acquiring a sufficient number of medical images to adequately train DNNs. The deep learning method is currently popular however, application to medical fields remains challenging. Since GoogLeNet outperformed humans in 2014 1, efforts to develop a high-performance classifier in various areas have continued. However, due to the success of deep learning, recent attempts to achieve a high-performance classifier with a deep neural network (DNN) that only inputs images have increased. In the classical diagnosis process, the radiologist reads the image and notes the findings, and then the physician makes a corresponding diagnosis and appropriate decision. In general, X-ray images and radiology reports offer complementary information to a physician who wants to make an informed decision. This finding demonstrates the potential for deep learning to improve performance and accelerate application of AI in clinical practice. When using a dataset of only 459 cases for algorithm training, the model achieved a favorable performance in a test dataset containing 227 cases (classification accuracy of 86.78% and classification F1 score of 0.867 for fracture or normal classification). The proposed model learns representation for classification from X-ray images and radiology reports simultaneously. This is a type of meta-learning method used to generate sufficiently adequate features for classification. To overcome this limitation, we present an encoder-decoder structured neural network that utilizes radiology reports as ancillary information at training. However, different forms of fracture exist, and inaccurate results have been confirmed depending on condition at the time of imaging, which is problematic. Numerous attempts have been made to diagnose and classify diseases using image data. In the medical field, various studies using artificial intelligence (AI) techniques have been attempted.
