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

With the wide application of intrusion detection system, the requirement of testing and evaluating intrusion detection system is more and more urgent. Developers want to test and evaluate the deficiencies in the product, users want to test and evaluate to help themselves choose the right intrusion detection products. Based on the current research, this paper intr

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

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

The code is as follows (take

DetectionAt present, the feature detection for Webshell is usually carried out through the static detection of characteristic ratio and file attribute anomaly, and the dynamic detection mode based on the access condition and behavior pattern feature, because spy type Webshell is often disguised as normal Web script file. Static feature

(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
