9 Anomaly Detection9.1 Density Estimation9.1.1 Problem MotivationAnomaly detection (Density estimation) is a common application of machine learning and is mainly used for unsupervised learning, but in some ways it is similar to supervised learning.The most common application of anomaly detection is fraud detection and in the industrial production field.In particu

It has been a very popular research area, and a quick search with "motion detection" on the IEEE Xplore wil

Anomaly detection, sometimes called outlier detection, English is generally called novelty Detection or outlier Detection, is a relatively common class of unsupervised learning algorithm, here on the anomaly detection algorithm to do a summary.1. Anomaly

Zero-day attacks and distributed denial of service (DdoS) attacks brought by increasingly large botnets, many small and medium-sized enterprises that use traditional security equipment are exhausted, and the active defense technology can effectively solve the security problems brought about by these aspects. Intrusion detection and defense system (IDS/IPS) is an active defense technology that installs them in key locations of the network and detects a

In the days when the network is booming, network security issues have become increasingly prominent. Black and white channels on the network are fiercely competitive in various fields of network security. The Black Hat community is constantly introducing new technologies to avoid or bypass Network Intrusion Detection Systems (NIDS). NIDS developers are constantly adding Detection techniques to their own pro

In the. \ opencv \ doc \ vidsurv folder, there are three doc FILES: blob_tracking_modules, blob_tracking_tests, and testseq. Among them, blob_tracking_modules must be read in detail.

In the machine learning field, there are usually multiple models available for most common problems. Of course, each model has its own characteristics and may be affected by different factors and behave differently. The quality of each model is determined by evaluating its performance on a certain dataset,This dataset is usually called a "verification/test" dataset.This performance is measured by different statistics, including accuracy, precision, and recall. We will select the corresponding st

The edge of the image is focused on the most information of the image, the determination and extraction of image edge is very important for the whole ima

This series of blogs introduces the development of mini-games in the Python+pygame library. There is the wrong point of writing and hope you haihan.Previous blog We learned about the Sprite module in Pygame and how to load the animation: http://www.cnblogs.com/msxh/p/5013555.htmlThis time we are going to study conflict detection techniques in pygame.Pygame supports a very great number of conflict detection

Collision Detection, also known as conflict detection, is a method to determine whether the elves conflict with each other. Collision Detection is used to determine when a physical interaction occurs between Elves. For example, in a game, if the player genie collide with the little plane genie, the player's life will be reduced. Collision

(Declaration: The following object-oriented ideas are based on C ++ and 2D graphics) In a program with a small amount of code, we may directly encapsulate the collision detection of all required objects in the class, and then Automatic Collision Detection is performed during rendering of actions such as role movement. However, this practice has a drawback, that is, we have known the requirements, If we need
