The classification puts Omicron into the most-troubling category of COVID-19 variants, along with the globally dominant Delta, plus its weaker rivals Alpha, Beta and Gamma. There are many studies that are underway to better characterize the variant. Follow CGTN for more details....

Vapnik developed support vector machine (SVM) algorithms to tackle classification problems in the 1990s. These algorithms find an optimal hyperplane, which is a line in a 2D or a 3D plane, between two dataset categories to distinguish between them. SVM eases the process of the machine learning...
Cohen’s kappa statistic is broadly used in cross-classification as a measure of agreement between two observed raters. It is an appropriate index of agreement when ratings are nominal scales with no order structure. The new WEIGHTED KAPPA command is an important generalization of the kappa statist...
What is the VED classification of inventory? What is a float in stocks? What are stock options? What are preferred stocks? What are stock fundamentals? What is an example of a vendor managed inventory? What are OTC stocks? What is alpha in stocks?
between classes, which are hard-margin classification and soft-margin classification. If we use a hard-margin SVMs, the data points will be perfectly separated outside of the support vectors, or "off the street" to continue with Professor Hinton’s analogy. This is represented with the formula...

A lot of you might think that{‘C’: 100, ‘gamma’: ‘scale’, ‘kernel’: ‘linear’}are the best values for hyperparameters for an SVM model. This is not the case, the above-mentioned hyperparameters may be the best for the dataset we are working on. But for any other dataset...

Ensemble learning is a machine learning technique that describes the use of ensemble models, where multiple indi...
