called classification problem.Linear regressionSuppose the price is not only related to the area, but also to the number of bedrooms, as follows:At this time \ (x\) is a 2-dimensional vector \ (\in \mathbb{r^2}\). where \ (x_1^{(i)}\) represents the house area of the first ( i\) sample,\ (x_2^{(i)}\) represents the number of house bedrooms for the first \ (i\) sample.We now decide to approximate y as the linear function of x, which is the following f

This article introduces the concepts of fitting and under-fitting, and introduces local weighted regression algorithms.Over fitting and under fittingBefore in linear regression, we always put the individual x as our characteristic, but in fact we can consider that even the higher times of x as our characteristics, then we will get through linear regression is a multiple function.We can imagine that when we

1. Vector TransformationVector transformation is a function from one vector space to another (or the same) vector space. In the vector world, this function is called transformation, which is usually represented by the symbol t. 2. linear transformationFor a vector Transformation: T: Rm-> RN, if T (a + B) = T (A) + T (B) and T (CA) are satisfied) = CT (A), transformation T is linear transformation. 3. matrix

Background:linear-gradient (180deg, Sliver 20%, Skyblue 80%, Gray 100%);180deg is the angle of the linear gradient, the horizontal direction, or, if it is 90deg, the vertical direction.The silver 20% is the topmost color and the position of the color, which can be negative, asLinear-gradient (180deg, silver-7%, Pink 80%, Skyblue 127%);The effect is:The second parameter: to-left, to-top, to-right, to-left-bottom, to-left-top, to-right-bottom, to-right

Linear Fitting: for the form of Y = A * x + BA = (N * Σ Xi * Yi-Σ Xi * Σ Yi)/(n * Σ Xi * Xi-(Σ xi) 2)B = (Σ Xi * xi) * (Σ Yi)-(Σ xi) * (Σ Xi * Yi)/(n * Σ Xi * Xi-(Σ XI) 2)MATLAB built-in functions can be used to achieve:Fitting Function: Pn = polyfit (X, Y, n) returns the PN coefficient vector, descending order, and N is the order.Function: yy = polyval (Pn, x) PN is a polynomial coefficient in descending order, X is a vector or matrix, and returns YY

Data Structure Learning-linear table, linear Data Structure Learning Linear tables are generally divided into sequential and chained structures. The addresses of elements in the sequence table are continuous, such as arrays. The addresses of nodes in the chain table are not consecutive and are connected by pointers, such as a single-chain table;Advantages and

What is the practical significance of linear algebra? What is the matrix? What does the operation between matrices represent? Many people still don't understand these questions at school, so I think we should start with understanding the nature of the course. There are only a few articles or answers that provide an understanding of the nature of linear algebra. Bloggers repeatedly read several times to dee

How to Use CSS3 linear gradient (linear-gradient) to achieve text wavy line Effect When reading paper books, we often use strokes to highlight the key content to enhance our visual experience. On the web page, we can only use background images to implement similar functions without CSS3. This is of course not an efficient method and is difficult to maintain and adjust. For example, if you just want to adjus

Linear discriminant Analysis (Linear discriminant Analyst) (ii)4. ExampleThe spherical sample points on the 3-dimensional space are projected onto two dimensions, and W1 can achieve better separation than W2.Comparison of the dimensionality reduction between PCA and LDA:The PCA selects the sample point projection with the direction of the maximum variance, and LDA chooses the best way to classify the perfor

Linear discriminant Analysis (Linear discriminant Analyst) (i)1. QuestionsBefore we discussed the PCA, ICA or the sample data to say, can be no category tag Y. Recall that when we do the regression, if there are too many features, then there will be irrelevant features introduced, over-fitting and so on. We can use PCA to reduce dimensions, but PCA does not take the category tag into account and is unsuperv
