An ANN is a model based on a collection of connected units or nodes called "artificial neurons", which loosely model the neurons in a biological brain. Each connection, like the synapses in a biological brain, can transmit information, a "signal", from one artificial neuron to another. An artificial neuron that receives a signal can process it a…
SQL Injection attack is the most common website hacking technique. Most websites use Structured Query Language (SQL) to interact with databases. SQL allows the website to create, retrieve, update, and delete database records. It used for everything from logging a user into the website to storing details of an eCommerce transaction. An SQL inject…
A denial of service attack floods a website with a huge amount of Internet traffic, causing its servers to become overwhelmed and crash. Most DDoS attacks are carried out using computers that have been compromised with malware. The owners of infected computers may not even be aware that their machine is sending requests for data to your website.…
In developmental robotics, robot learning algorithms generate their own sequences of learning experiences, also known as a curriculum, to cumulatively acquire new skills through self-guided exploration and social interaction with humans. These robots use guidance mechanisms such as active learning, maturation, motor synergies and imitation. Asso…
In some cases, the greatest weakness in a website’s security system is the people that use it. Social engineering seeks to exploit this weakness. A hacker will convince a website user or administrator to divulge some useful information that helps them exploit the website. There are many forms of social engineering attacks, including: Phishing Us…
In many cases, hackers won’t specifically target your website. They will be targeting a vulnerability that exists for a content management system, plugin, or template. For example, they may have developed a hack that targets a vulnerability in a particular version of WordPress, Joomla, or another content management system. They will use automate…
The classical problem in computer vision, image processing, and machine vision is that of determining whether or not the image data contains some specific object, feature, or activity. Different varieties of the recognition problem are described in the literature:[citation needed] Object recognition (also called object classification) – one or s…
Military applications are probably one of the largest areas for computer vision. The obvious examples are detection of enemy soldiers or vehicles and missile guidance. More advanced systems for missile guidance send the missile to an area rather than a specific target, and target selection is made when the missile reaches the area based on local…
Reinforcement learning is an area of machine learning concerned with how software agents ought to take actions in an environment so as to maximize some notion of cumulative reward. Due to its generality, the field is studied in many other disciplines, such as game theory, control theory, operations research, information theory, simulation-based …
A second application area in computer vision is in industry, sometimes called machine vision, where information is extracted for the purpose of supporting a manufacturing process. One example is quality control where details or final products are being automatically inspected in order to find defects. Another example is measurement of position a…
Self-learning as a machine learning paradigm was introduced in 1982 along with a neural network capable of self-learning named crossbar adaptive array (CAA).[44] It is a learning with no external rewards and no external teacher advice. The CAA self-learning algorithm computes, in a crossbar fashion, both decisions about actions and emotions (fee…
This hacking technique injects corrupt domain system data into a DNS resolver’s cache to redirect where a website’s traffic is sent. It is often used to send traffic from legitimate websites to malicious websites that contain malware. DNS spoofing can also be used to gather information about the traffic being diverted. The best techniques for pr…
Supervised learning algorithms build a mathematical model of a set of data that contains both the inputs and the desired outputs.[38] The data is known as training data, and consists of a set of training examples. Each training example has one or more inputs and the desired output, also known as a supervisory signal. In the mathematical model, e…
Cross Site Scripting is a major vulnerability that is often exploited by hackers for website hacking. It is one of the more difficult vulnerabilities to deal with because of the way it works. Some of the largest websites in the world have dealt with successful XSS attacks including Microsoft and Google. Most XSS website hacking attacks use malic…
