Others ask questions of the post, casually hit some, talk about their views. Original posts: http://bbs.51testing.com/thread-475716-1-1.html 1. How to improve the defect detection rate in the test process, so that the test problem as far as possible in the first to second round of discovery, reduce the number of bug per round.Defect detection rate, more to understand the program and business, in other w

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

(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

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 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

Heartbeat is often used in distributed systems to detect the health status of the server. However, in theory, heartbeat cannot really detect the other party's crash, the main difficulty lies in the inability to distinguish between downtime and slowness ". The traditional detection method is to set a timeout time t. As long as the heartbeat packet of the other party is not received within T, the other party is considered to be down. The method is simpl

1. BackgroundException detection can be defined as "making decisions based on the actions of actors (persons or machines)". This technology can be applied to many industries, for example, transaction detection and loan detection are performed in Financial Scenarios, production line warning is performed in industrial scenarios, and ***

For classification, it is to divide a given picture into one of several categories given. It is clear that only one object in the given category can exist in the image.2. The p

It mainly replaces system files for intrusion and concealment. This Trojan is more dangerous and concealed than a common backdoor, it is difficult to find such Trojans through common detection tools and detection methods. Th

Collision detection, also known as conflict detection, is a way to determine whether the elves are conflicting with each other. Collision detection is used to determine when physical interactions occur between elves. For example, in a game, the player's life will be reduced if the player's sprite collides with a small-plane sprite. Collision
