square feet size house to sell, then based on the above data, how do you speculate about how much the house worth. For this problem, we can apply the machine learning algorithm, draw a line in this set of data or a line of quasi-unity, according to this line we can speculate that the house may sell $000. Of course, this is not the only algorithm, such as a two-t

the WTW:The essence is similar.Another understanding: If we consider the constraints in SVM as a filtering algorithm, for a number of points in a plane,It is possible that some margin non-conforming methods will be ignored, so this is actually a reduction of the problem of the VC dimension, which is also an optimization direction of the problem.With the condition of M > 1.126, better generalization performance was obtained compared to PLA.Taking a circle midpoint as an example, some partitionin

very good. But the immune algorithm can develop better in the next 2 years. Under such circumstances, what is better than learning?? I think. Suppose you have advanced mathematical skills, very good thinking. There are a lot of creative friends, and my advice is to develop new algorithms. Like the immune algorithm class. Of course it would be better if we could create a bee-building algorithm. It is expect

inspire rewards by trying and using errors to reveal specific actions. The agents can then use these rewards to understand the best state of the game and choose the next action.Quantifying the prevalence of machine learning algorithmsSome research reports (http://www.cs.uvm.edu/~icdm/algorithms/10Algorithms-08.pdf) have been done to quantify 10 of the most popular data mining algorithms. However, such a li

1. What is manifoldManifold Learning Viewpoint: We think that the data we can observe is actually mapped by a low-dimensional pandemic to a high-dimensional space. Due to the limitations of the internal characteristics of the data, some of the data in the higher dimensions produce redundancy on the dimension, which in fact can be represented only by a lower dimension. So intuitively speaking, a manifold is like a D-dimensional space, in a m-dimensiona

methods use optimization algorithms directly or indirectly.According to the function and form similarity of the algorithm, we can classify the algorithm, for example, tree-based algorithm, neural network based algorithm and so on. Of course, the scope of machine learning is very large, and some algorithms are difficult to classify into a certain category. For so
