Abstraction principle (computer programming). Compared with the state-of-the-art methods, our model achieved better results. ; software, J.H. We chose fps as a metric to measure inference time, which expresses as, For AUVs and ROVs, during underwater exploration activities, the purpose of improving the image quality is to improve the accuracy of tasks such as object detection and classification. Social Studies: Students coalesce the most important details shared in articles about a specific current event and write a brief about the event. This approach is often called computational thinking and is similar, in many ways, to the scientific method where were concerned with making predictions. SSIM is a metric used to measure the similarity of images, and it can also be used to judge the quality of images after compression. Another way to think about abstraction is in the context of those big concepts that inform how we think about the world like Newtons Laws of Motion, the Law of Supply and Demand, or the Pythagorean Theorem. When a patient discusses symptoms with a doctor or undergoes a series of tests, the results are compared against known patterns to quickly identify types of infections or injuries that may be causing the symptoms and to apply corresponding solutions to the diagnoses. Abstraction means hiding the complexity of something away from the thing that is going to be using it. Cognitive Science, 12(2), 257285.
