1 Introduction K-means and kNN may both start with ‘k’, but they are two different types of algorithms—kNN is a classification algorithm in supervised learning, while k-means is a clustering algorithm in unsupervised learning. The similarity between the two is that both utilize neighbor information to label categories. Clustering is a very important learning paradigm … Read more
Knowledge graphs have many applications, such as intelligent search, question-answering systems, recommendation systems, and information extraction. They can help people better organize and utilize vast amounts of knowledge, providing smarter and more personalized services. The concept of knowledge graphs originated in the field of artificial intelligence and is a technique used to represent and organize … Read more
The lung’s diffusion function is one of the most challenging physiological indicators to grasp!! First, we need to avoid the influence of lung ventilation, (See details in “Evaluation of Lung Ventilation Function“) We also need to avoid the influence of pulmonary blood flow, (See details in “Pulmonary Hypertension” and “Pulmonary Embolism” ) Finally, we must … Read more
