来不及-罗忆诗

习惯一个人看戏
习惯一个人旅行
习惯一个人静静想你
想你现在在哪里
想你会为谁担心
想你是否已忘记
忘记那段爱情
忘记那颗泪滴
忘记了所有不该忘的回忆

我来不及将你的手紧紧握着
对你说我只想要我们能快乐
曾以为少了你的陪伴不算什么
怎么我微笑着 心却是痛的
我来不及将记忆中的你消除了
我明白错过的从此难以复合
如果眼泪能够证明我是爱你的
那么重新选择是不是来不及了

忘记那段爱情忘记那颗泪滴
忘记了所有不该忘的回忆
我来不及将你的手紧紧握着
对你说我只想要我们能快乐
曾以为少了你的陪伴不算什么
怎么我微笑着 心却是痛的
我来不及将记忆中的你消除了
我明白错过的从此难以复合
如果眼泪能够证明我是爱你的
那么重新选择是不是来不及了

我来不及将你的手紧紧握着
对你说我只想要我们能快乐
曾以为少了你的陪伴不算什么
怎么我微笑 着心却是痛的
我来不及将记忆中的你消除了
我明白错过的从此难以复合
如果眼泪能够证明我是爱你的
那么重新选择是不是来不及了
我还是来不及了

Fifth Generation (Present and Beyond) Artificial Intelligence

 

Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.

  

Artificial intelligence (AI) is the intelligence of machines and the branch of computer science that aims to create it. AI textbooks define the field as “the study and design of intelligent agents” where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. John McCarthy, who coined the term in 1956, defines it as “the science and engineering of making intelligent machines.”

  

The field was founded on the claim that a central property of humans, intelligence—the sapience of Homo sapiens—can be so precisely described that it can be simulated by a machine. This raises philosophical issues about the nature of the mind and the ethics of creating artificial beings, issues which have been addressed by myth, fiction and philosophy since antiquity. Artificial intelligence has been the subject of optimism, but has also suffered setbacks and, today, has become an essential part of the technology industry, providing the heavy lifting for many of the most difficult problems in computer science.

 

AI research is highly technical and specialized, deeply divided into subfields that often fail to communicate with each other. Subfields have grown up around particular institutions, the work of individual researchers, the solution of specific problems, longstanding differences of opinion about how AI should be done and the application of widely differing tools. The central problems of AI include such traits as reasoning, knowledge, planning, learning, communication, perception and the ability to move and manipulate objects. General intelligence (or “strong AI”) is still among the field’s long term goals.

Fourth Generation (1971-Present) Microprocessors

 

The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central processing unit and memory to input/output controls—on a single chip.

 

In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh. Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors.

 

As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.

Third Generation (1964-1971) Integrated Circuits

                                                                             

The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.

                                                                                 

    .

Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.
