Machine learning is divided into two major categories, supervised learning (supervised learning) and unsupervised learning (unsupervised learning). Supervised learning can be divided into two categories: classification (classification.) and regression (regression), the task is to classify a sample into a known category, each sample of the class information in training needs to be given, such as face recognition, behavioral recognition, target detection are classified. The task of regression is t

machine Learning Combat (Chapter II: K-Nearest neighbor algorithm) Today I studied the second chapter, here I understand to do a simple summary, is to deepen my understanding and in my own language to describe the algorithm. Distance Calculation Computation of Euclidean distance based on vector space. (L2 distance) In particular, LP distance (L1 distance) can be used for distance. The simple point is that in a large sample concentration, each instan

First, the algorithm flow (1) Data collection: Any method can be used; (2) Preparation of data: distance calculation of the required value, preferably structured data format; (3) Analysis data: can use any method; (4) Training algorithm: This step does not apply to K-nearest neighbor algorithm; (5) Test algorithm: Calculate error rate; (6) Using the algorithm: first, we need to input sample data and structured output, and then run K-

A series of articles on postgraduate courses see the Basic principles of those courses in the Faith section Assuming that two data sets P and Q have been given, the space transformation F of the two point sets is given to enable them to perform spatial matching. The problem here is that f is an unknown function, and the points in the two-point set are not necessarily the same. The most common way to solve this problem is to iterate over the nearest po

Hundred vision of the popular network recently increased capital of 400 million yuan, the equity increase to 82.76%, completed the popular network of Absolute holdings. It is not difficult to see, overweight means that the advantages of a strong resource and channel to the popular network tilt, Popular will have a bigger stage and opportunities, its long-established network integration from the capital to the organization level, and the popular networ

There was a young and beautiful girl who was born from a great family. She had a rich family and a versatile family. She had a good time. The matchmaker also broke her family's door, but she never wanted to get married because she thought she hadn't seen the boy she really wanted to marry. One day, she went to a temple fair, and saw a young man in the crowd, the girl thinks that man is the result of her waiting. Unfortunately, the temple fair was so crowded that she could not walk to the man's s

In the Baidu Guardian software interface, there is a treasure box function, then, Baidu Bodyguard hundred treasure Box what function? Now we will open the Baidu Guardian's hundred treasure box to find out. Of course, in this tutorial, we can also learn to Baidu bodyguard hundred treasure box in the use of gadgets, want to know netizens, don't miss! B

Let's talk about the story from the warring States. Su Qin was a hacker during the Warring States period. He was wearing a photo of the six countries, and he was very awesome at the moment, but he also made a lot of enemies. Later, he was finally killed in Qi Guo. Qi Wang was angry and wanted to avenge SU Qin. But at the moment he could not find the murderer, so he thought of a plan to let people cut sutai's head from the body and hung it on the gate. Next to it, he said: "Su Qin was an insider,

Recent point-to-point problem definition: a set of M points is known to locate a pair of close points.In two-dimensional space, you can use the divide and conquer method to solve the closest point problem. Pre-processing: sort the values based on the X axis and Y axis respectively to obtain X and Y. Obviously, the points in X and Y are the points in S. Case (1): When the number of points is less than or equal to three hours: Case (2): When the number of points is greater than three: First, th

1. Brief Introduction Specify the coordinates of N points on the plane to locate the two closest points. 2. IdeasThe brute force method is the complexity of C (n, 2) and N ^ 2. The binary method, for example, first sorts all vertices according to the abscissa and recursively Splits them. Termination condition: returns the result when only one vertex or two vertices exist. If one vertex is null, the two vertices are returned. Recursive process: Calculate the closest point between n/2 points on th

is possible that when a new sample is input, the samples with a large capacity class in the K neighbors of the sample account for the majority. Therefore, we can use the method of weight (a large neighbor weight with a small distance from the sample) to improve. Another disadvantage of this method is that the calculation workload is large, because the distance from the text to all known samples must be calculated for each text to be classified before K Near
