1. Problem We have discussed PCA and ICA before. For sample data, there can be no category label y. Recall that when we perform regression, if there are too many features, there will be unrelated feature introduction, over-fitting, and other

7-core function (kernels) Considering the problem we raised in "linear regression", the feature is the area X of the house, where X is a real number, and Y is the price of the house. Assuming that X and Y conform to three curves from the

QAM (Quadrature Amplitude Modulation): Orthogonal amplitude modulation. Orthogonal amplitude modulation is a signal modulation method that has been highly valued by mobile communication technical experts in recent years. QAM is a modulation method

The previous content of this article is "Factor Analysis". Due to its extraordinary theories, I plan to finish the entire course and then write it again. Before writing this article, I have read PCA, SVD, and lda. These models are similar, but they

Windbg debug ASL Windbg uses the host and target methods for debugging. This is a common system-level debugging method. It uses the host machine to debug the target machine. Therefore, two machines are generally required ..1. Connect the two
