| dc.description.abstract | With the development of science and technology, artificial intelligence has played a very important role. The advantage of machines is that they can repeat work without fatigue. In recent years, many people have begun to discuss how to make machines have human-like intelligence to make this field fast developed in these years. Machine learning plays a very important role in perception and estimation. Among them, machine learning can be divided into four types: supervised learning, unsupervised learning, semi-supervised learning, and enhanced learning. Among them, neural networks play a very important role in machine learning. Perception and estimation can use the known information to deduce more future information.
Image recognition plays an important role in artificial intelligence, such as animal recognition, handwriting recognition, and license plate recognition. The main purpose of using deep learning is to be able to extract features and reduce costs, but it is not so easy to make a good classification, many factors will affect each other. For example: computer equipment, parameter setting, optimizer selection, model architecture.
The pictures of pneumonia in this experiment come from kaggle, and use the method of convolutional neural network to establish a pneumonia identification model, selecting several ways that may affect the identification of pneumonia as the object of discussion and analysis. From the experimental results, it is found that the dropout ratio, optimization method, transfer learning, freezing parameters, and the number of convolutional layers all affect the performance of the model. Keywords: machine learning, volume-based layered network, deep learning, reinforcement learning, optimizer, filter, transfer learning. | en_US |
