This article is about 11,000 words long and is recommended to be read in over 10 minutes. This is a survey overview of large models for time series and spatio-temporal data. Time-related data, especially time series and spatio-temporal data, are ubiquitous in real-world applications. These data capture measurements of dynamic systems and are generated in … Read more
Click the above “Mechatronic Engineering Technology” to follow us The geometric modeling kernel is a software component used to provide 3D modeling capabilities in computer-aided design (CAD) software. It is used to design virtual models to support the simulation and manufacturing of real objects. The geometric modeling kernel uses various geometric representations to represent real … Read more
Click on the above “Beginner Learning Vision”, choose to add “Star” or “Top” Heavyweight content delivered first-hand We train and learn the models well, and only through objectively evaluating the model’s performance can we make better practical decisions. Model evaluation mainly includes: prediction error situations, degree of fitting, model stability, etc. There are also some … Read more
Hello everyone~ Today we are going to talk about a probabilistic model – Gaussian Mixture Model (GMM). Gaussian Mixture Model is like a complex fuzzy grouping mechanism, believing that a dataset is actually composed of multiple “small groups,” where things within each “small group” are roughly distributed according to a bell curve (Gaussian distribution). You … Read more
Step-By-Step Guide to Building Clinical Prediction Models STEP 1 Purpose, Team, Review, and Plan 1 Clarify the Purpose of the Prediction Model Define the objectives of the prediction model, including: Target population: Specify the patient group the model is aimed at, such as HIV patients in South Africa, individuals with a history of diabetes, or … Read more
There are numerous models in mathematical modeling, but looking through the past competition problems of the National and American competitions, the main types frequently tested in mathematical modeling competitions are: evaluation type, prediction type, optimization type, and mechanism analysis type. Evaluation type problems require assessing and analyzing a certain system, phenomenon, or plan. When modeling … Read more
