We may write the basic structure of a linear programming problem in what is called canonical form as: maximize a linear functional or hyperplane$$ f({{x}_{1}},...,{{x}_{p}}) = {{c}_{1}}{{x}_{1}} + \\cdots + {{c}_{p}}{{x}_{p}} $$ (3.1) subject to (...

1. Introduction to vectors 1.1 Vectors and Linear Combinations The elements of a vector are called “components”. Linear combinations contain vector addition and scalar multiplication. A linear combination of v and w is the sum of cv and dw. ...
f(x)=max(0,x) ReLU function is its derivative both are monotonic. The function returns 0 if it receives any negative input, but for any positive value x, it returns that value back. Thus it gives an output that has a range from 0 to infinity. ...
The third hides in the shadows of linear algebra textbooks and is the concept of basis vectors. The order of these basis vectors, which defines the coordinate system (and therefore the direction of the axes of the coordinate system and more), is very important. To be able to talk about tr...
An Introduction to Shader InterfacesMatt Pharr NVIDIAThe release of Cg 1.2 introduced an important new feature to the Cg programming language called shader interfaces. Shader interfaces provide functionality similar to Java or C# interface classes and C++ abstract base classes: they allow...
Here are some examples about feature extraction methods and indicator groups, you are more than welcome to try other methods as well. Feature extraction methods: Principal Components Analysis (PCA), Independent Component Analysis (ICA), Linear Discriminant Analysis (LDA), Locally Linear Embedding (LLE...
