Many students asked me questions about algorithms. In fact, as long as banco born, he should be asked in the development or interview. For example, one of the sorting algorithm. Let me explain to you what is the algorithm and what is artificial intelligence algorithms. Today to unlock the mystery.
Algorithm in the end is what?
Algorithm is a series of clear instructions to solve the problem of accurate and complete description of the program, but also to solve the problem. The algorithm is a systematic method of describing the policy mechanism to solve the problem. In other words, for a particular standard input, a desired output can be obtained within a limited time. If an algorithm is defective or is not suitable for an issue, the implementation of the algorithm does not solve the problem. Different algorithms may use different time, space or efficiency to accomplish the same task. Advantages and disadvantages of the algorithm can be measured by the complexity and time complexity of space.
Speaking algorithm, you might think of the program. In the early computer problem, we try to human knowledge, such as computing, entered into the computer, and then solve the problem through the program, we usually call algorithms. We can say that now is the computer age, neural network algorithm has been fully changed our lives. Firstly, the expression of human logic, you can usually use mathematical formulas or some symbolic language to express. Then we express this logic through accurate operation of the transistor, and then help humans work.
In order to understand exactly what the algorithm is a very typical example of the sort is a very classic algorithms. Numbers in chaotic way pile up. We must put them in descending order. Then, we will specify a process, so that the data string in, and then neatly from largest to smallest, which is an algorithm. what can we do? There are countless ways. The easiest way is to compare each of the data from left to right with the adjacent data. Every encounter is larger than its own data, will move to the right a grid. When you encounter smaller than your data, you will not move. Then you continue relatively small data, minimum data will eventually sink. Then you handle the remaining data and cycle back and forth, you can grow from small to large. Of course, we can invent numerous processes to achieve this, such as inserting method, heap sort, and so on. However, all things being equal, this is a process can be implemented automatically, each step according to certain rules, to obtain the desired result. We can see that the algorithm automates the process of human logic.
Almost the same principle can be said to be a simple algorithm bubble, many artificial intelligence algorithms are used in the framework of this principle.
In addition, the algorithm is not necessarily the program. By given rules and automated processes, you can get results. As long as this is the case, with or without a computer it can be seen as an algorithm. For example, biological evolution can be seen as a huge evolutionary genetic algorithm. At first there are a bunch of blasts. Then you specify a process, cells can produce new cells genetically identical in this process. This process is subject to error and mutations. Natural environment may then choose a favorable mutations. As long as there is enough iterations, the result of this algorithm is that all complex life type. Interested in old iron can read my article (if Nu Wa created man is true, then we will repeat this process it in training artificial intelligence model? Some social phenomena, such as the regulation of the free market economy, can also be considered for the algorithm. you can go back to think of intelligence life is predictable, but there is still a long way to go.
I always say that the future is the era of artificial intelligence, but how far away is easy to overlook a problem or a media organization or some avoidable problem. universal artificial intelligence is the future mainstream of development. no problem, but no one can guarantee how long it takes. in fact, we are still in the early "oinai" of.
However, from the current research and awareness, we can foresee the future of some of the scenes of life.
Factory by robotic manipulation, anywhere high risk have been replaced by robots. We just need to control the robot through the program, and to rest and enjoy a very short period of time every day. Lying in the car after work, a time autopilot technology has matured, by positioning automatically to anywhere you want to go.
With the popularity of smart home, smart butler Japanese women at that moment you get home to welcome you home, asking if you want to take a bath or eat, then run through the automatic control of home appliances intelligent control. All you have to do is lie back and enjoy it brings you service. Meanwhile, the smart bracelet will be assessed by your heartbeat and blood flow to your physical condition, your risk even predict how long it will bring you diseases, and eliminate these risks according to the analysis.
