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 formula:\[h_{\theta} (x) =\theta_0+\theta_1x_1

1.LMS algorithms are primarily a matter of relevance2. What is the implementation process of LMS algorithm?3. How does stepping affect the algorithm?If the step size is large, the convergence is fast, but the offset is large and the step size is small, but the convergence is slow.In the initial phase of the algorithm, a large U-value should be adopted to accelerate the convergence, and then the smaller U-va

Java initialization and cleaning, java initialization cleaning Exercise 1: Create a class that contains an uninitialized String reference. Verify that the reference is initialized to null by java. Exercise 2: Create a class that contains a String field initialized during definition, and a String field initialized by construction. What are the differences between the two methods? 1 package com; 2 3 publ

First, introduce The main content of data cleaning is to delete irrelevant data, duplicate data, smooth noise data in the original data set, brush off the data unrelated to the mining topic, and deal with the missing value and outliers. Second, missing value processing The method of missing value processing is divided into three categories: deleting records, data interpolation and not processing. The common data interpolation method is as follows: Am
