"Business Technology" has collected opinions from dozens of companies who believe that artificial intelligence (AI) will dominate the global technology industry in the visual field in 2018. As always, it is closely watched by cyber security. Whether it is to help identify diseases, develop new drugs, or promote driverless cars and air traffic management systems, people's consensus is that AI will begin to be implemented in 2018, and it also proves that hype hysteria sometimes occurred last year. 2018 will be the year that AI really takes off. It will be almost everywhere. But is AI an enemy or an ally? How much freedom should we give artificial intelligence systems without the need for human intervention? Cyber ​​Security: "Armed AI" Although many cyber security companies point out the potential of AI in combating cyber attacks (such as real-time monitoring of computer networks to detect signs of abnormal behavior), others are clearly aware that AI will also be "weaponized" by hackers. Dr. Adrian Nish, Head of Threat Intelligence at BAE Systems, warned: “In 2018, it may be the first time we have seen artificial intelligence robots (AI) fighting.†"It's inevitable that the attackers began to combine machine learning and artificial intelligence. This is just as fast as the development of network defense tools. We may have been at this time. Online Twitter bots can respond to emerging events and create The news responded." Dave Palmer, chief technology officer of Darktrace’s corporate security company, also stated that simple and effective e-mail phishing attacks, where employees believe that this information is from real people and are blinded to click on malicious links or download malware, may reach another level of complexity . He said: "Imagine that a malware can train its writing style. It depends on who you contact and uses different writing styles, and uses this style to send relevant information to your contacts. These networks The phishing information will be very real and the target objects will be confused by them. The progress of artificial intelligence will enable us to enter the next phase of defenders and attackers, and we need to be prepared." Incremental Encoder is commonly used, and Absolute Encoder is used if there are strict requirements on position and zero position. Servo system should be analyzed in detail, depending on the application situation. Commonly used incremental encoder for speed measurement, which can be used for infinite accumulation measurement; Absolute encoder is used for position measurement, and the position is unique (single or multiple turns). Finally, it depends on the application situation and the purpose and requirements to be realized.
