1. AI has realized the pursuit of human beings for the realm of go: to be simple, to win without fighting, to make the best use of the situation and to make no mistakes. Because of the lack of
computing power, it's no use learning any more. You can be a companion to broaden your mind.
2. Ali cloud
advantages: big brand, bundled Taobao, Alipay, etc. account registration and payment is convenient, proct line is perfect, autonomy is high;
disadvantages: the timeliness of after-sales service is poor, and the work order response speed is often more than half an hour; Disk IO is chicken ribs; There are many people who use it. The public says that the public is reasonable, and the old says that the old is reasonable
alicloud is the largest cloud service provider in China. Relying on years of technical experience of Taobao, tmall and Alibaba, it is still very strong. However, Amazon, as the pioneer of cloud computing, has the largest market share in the world, and its strength can not be small
here I would like to mention bird cloud computing. Although it has not been established for a long time and its brand awareness is not as high as that of the previous two companies, bird cloud focuses on high-end quality. The quality of its servers is very good and its security and stability are guaranteed.
3. The minimum monthly wage in Shanghai has been adjusted to 750 yuan, ranking the first in China. From September 1, the minimum monthly wage for employees in Shanghai will be increased from 690 yuan to 750 yuan, and the minimum wage for hourly workers will be increased from 6 yuan to 6.5 yuan. This is the 14th time in a row that Shanghai has raised the minimum wage system since it was first introced in China in 1993. Shanghai clearly stipulates that the minimum wage after the above-mentioned adjustment is the real income, and the basic social insurance premium and housing accumulation fund payable by indivials shall be paid separately by the unit. In other words, 750 yuan is the net income after excluding social security fees and other expenses, and this minimum wage standard is currently the highest in the country. At the same time, there are three policies to adjust the minimum living standard of urban and rural residents, the standard of pension subsidies for some special pension objects, and increase the remuneration for public welfare posts. For example, starting from August 1, the minimum living standard for urban residents in Shanghai has been raised from 300 yuan per person per month to 320 yuan; Starting from July 1, the minimum living standard for rural residents in the city will be adjusted from 2340 yuan per person per year to 2560 yuan per year. Yesterday, the Shanghai municipal government also approved the "opinions on special assistance for those who have agreed to retain social insurance relations" formulated by six departments, including labor security, medical insurance, civil affairs, finance, SASAC and the Federation of trade unions. This is another income distribution policy that benefits low-income groups. According to the policy, those who are within two years (including two years) of the legal retirement age who have achieved market-oriented employment and have been registered by the labor department can apply for employment subsidies ring the period of employment, and the subsidy standard is 50% of the minimum wage standard of the city in that year; For those who are unable to obtain employment e to serious illness or most of them lose the ability to work, and whose families have difficulties in living, they will be given living expenses subsidies. The subsidy standard is the minimum wage standard of the city in that year. The minimum monthly wage in Guangdong ranges from 450 yuan to 810 yuan. "Guangzhou workers whose monthly income is still less than 780 yuan can complain to the local labor supervision department or trade union." Starting from September 1, Guangdong will implement the new minimum wage standard for enterprises, which is the biggest increase since 1994. In order to make this security line not a mere decoration, the Department of labor and social security of Guangdong Province reminds workers to keep their eyes open and protect their own interests. According to the new plan, the minimum wage standard in Guangdong Province has increased by an average of 17.8% over the previous year. After the adjustment, the minimum wage standard of the province can be divided into five categories: one is 780 yuan / month, which is applicable to Guangzhou; The second category is 690 yuan, which is suitable for Zhuhai, Foshan, Dongguan and Zhongshan; 600 yuan for the third category; 500 yuan for four categories; Five categories: 450 yuan. At the same time, Shenzhen also raised the standard: 810 yuan / month in the special zone, and 700 yuan / month in Baoan and Longgang districts outside the special zone. This adjustment will directly benefit the low-income groups, especially the more than 23 million migrant workers in Guangdong, and alleviate the income gap to a certain extent. Huang Linyan, director of the wage Department of the Guangdong Provincial Labor and social security department, analyzed in an interview that the government's move will promote enterprises to change the mode of relying on low wage competition and enhance the attraction of Guangdong to migrant workers. At the same time, changing the mismatch between economic growth and personal income distribution is also one of the reasons for the adjustment. From 1995 to 2005, the GDP of Guangdong Province increased by 265.77%, while the minimum wage of employees increased by 89.2% on average, equivalent to 1 / 3 of the GDP growth rate. Fujian provincial government's general office recently issued a "notice on the announcement of the minimum wage standard in Fujian Province and the minimum wage standard for part-time employment hours in urban areas where cities are divided into districts". Starting from August, Fujian Province will adjust the minimum wage standard announced in 2005. According to reports, the minimum wage standard in Fujian will be between 400 yuan and 650 yuan. Among them, Siming District and Huli District of Xiamen City have the highest standard of 650 yuan, 50 yuan higher than last year's minimum wage standard; In some mountainous counties and cities in Fuzhou, Nanping, Sanming, Longyan and Ningde, the minimum wage was 400 yuan, 80 yuan higher than last year's minimum wage At the same time, the circular also announced the minimum hourly wage standard for part-time employment in the urban areas where the cities are divided into districts, of which the highest in Siming District and Huli District of Xiamen is 6.8 yuan / hour; The lowest in Sanyuan District and Meilie District of Sanming City, Yanping District of Nanping City, Xinluo District of Longyan City and Jiaocheng District of Ningde City were 4.5 yuan / hour, all slightly higher than the previous year. The person in charge of the labor and Social Security Department of Fujian Province said that the minimum wage is the minimum guarantee level for workers, not the actual wage level, nor the wage guidance line for enterprises and the wage guidance price for the labor market. It includes bonus, but does not include overtime pay and allowance under special working environment and conditions, as well as the welfare of workers stipulated by law and the state. The person in charge reminds workers to be alert to some unscrupulous owners who deliberately lower and exploit workers' e remuneration under the pretext of minimum wage standard. Qinghai has established the minimum wage standard for the first time. Starting from July 1 this year, Qinghai Province has adjusted the minimum wage standard. After the adjustment, the minimum wage standard for full-time workers will be greatly improved. At the same time, in view of the actual needs of flexible employment of employers and self employment of workers, Qinghai Province has also established the standard of hourly minimum wage for the first time. This adjustment is a large increase since the establishment of the minimum wage security system in Qinghai Province in 1995. After the adjustment, the minimum wage for full-time workers is 440 yuan per person per month in Xining and Haidong; Hainan, Haibei and Huangnan are 450 yuan per person per month; Haixi, Guoluo and Yushu are 460 yuan per person per month. The hourly minimum wage system is applicable to part-time workers. The specific standard is: the hourly minimum wage in Xining and Haidong is 5 yuan; The minimum wage of Hainan, Haibei and Huangnan is 5.1 yuan per hour; Haixi Prefecture, Guoluo Prefecture and Yushu prefecture have a minimum wage of 5.2 yuan per hour The regulations on minimum wage of enterprises was promulgated in 1993, and the Ministry of labor and social security formulated the regulations on minimum wage in 2004. In view of the long term and low level of the minimum wage standard in some areas, the new regulations clearly stipulate that the minimum wage standard should be adjusted at least once every two years

4. Bi directional, refers to the plate X direction and Y direction, LX is the plate X direction size, ly is the plate Y direction size. When the ratio of dimensions in these two directions is different, the load distribution in these two directions is different, so the load effect in these two directions is different (that is, the bending moment and shear force are different).
5. The two-way slab has two calculation directions, so there are two calculation spans. The calculated span shall be the distance between the two supports.
6. Staadchina is very good, but it is more difficult to learn
7. On the one hand, because of the complexity of the human brain, many areas have not been fully developed. On the other hand, learning mathematics has no evolutionary advantage
human brain is very powerful, but in the face of complex and changeable natural environment, we must pre install many moles to deal with it. As for the more complicated mathematical problems, how fast they can be calculated has little effect on people's survival ability. Moreover, after the human brain has pre installed these moles and used up these computing resources, the remaining computing power is still a lot, but it is far from being discretionary
so people can try their best to accomplish some tasks very well, but all of them are the results of arous training. Because hundreds of millions of years of biological evolution is not aimed at completing mathematical operations. The goal of these 100 billion neurons is to survive on the earth. And it's obviously not helpful to finish the math faster
in recent years, computer technology has developed by leaps and bounds. At that time, the computing speed of "dark blue" was about 200 million times per second. At present, tianhe-2, the world's strongest computer made in China, has achieved a computing speed of 3.386 billion times per second, which provides the possibility for computers to defeat the human brain. The wide application of cloud computing and big data makes the development of artificial intelligence even more powerful, and makes dreams come true
extended materials:
in order to verify again who is more powerful between computer and human brain, the online fish competition hall in Beijing Gongti West Road has become a competition place for Super Brain in black and white world, and the first Merrill Valley cup world computer Go Championship was held here
the teams from 9 countries and regions such as China, South Korea, Japan, the United States and France competed fiercely. Finally, the "stone whirlwind" developed by South Korean expert Lin Zaifan defeated "zenith go" from Japan in the final and won the computer championship
but when it comes to the "man-machine war", the computer will not be "smart" on the 19 track black-and-white board of go. In the game between computer and human brain held on the 15th, the computer "stone whirlwind" challenged the Chinese go celebrity champion for seven consecutive laughs. After the start of the competition, "stone whirlwind" layout is particularly thick, once in the dominant position, but unexpectedly in the middle of the line, there was a blind move
in the end, the players win in the match of let 4 and let 5, lose to the computer at the time of let 6, and win with the total score of 2:1. It seems that computer Go program is the way to win over human beings

8. In order to enter the artificial intelligence instry, we must first have a certain mathematical foundation, because artificial intelligence is different from app development, web development, game development and other traditional internet jobs. We can check the API call function or beautify the interface every day
Artificial intelligence is evolved from "approximation theory" in mathematics. At the beginning, most of the methods used in artificial intelligence are used by mathematicians to approximate some nonlinear functions which are difficult to express. Later, with the improvement of computer performance, computer workers and statisticians began to try to use this set of "approximation theory" to solve some classification problems. Graally developed into the current situation of artificial intelligence
2. At the beginning of the development of artificial intelligence instry, there are few API functions available, so it is necessary to write your own algorithm. For the engineers who want to master the knowledge of artificial intelligence, mathematics is an unavoidable obstacle
Artificial intelligence is a big concept. Nowadays, the so-called AI applications of many companies are still in the primary stage, such as information (data) classification, filtering, pattern recognition and so on. Many languages have formed code packages, open source code and so on, More is the need for the support of big data, constantly optimize the algorithm
4. Now some popular intelligent devices, smart home, I don't think it is artificial intelligence, but more is the application of various sensors and program rules. Maybe this kind of instry will be closer to life and more market. The prospect is very promising. However, just like making software, it's not sure that a good software proct can be made with good technology. It's necessary to have a deep understanding of user needs and pay attention to user experience. In your background, I think it may be better to develop in this direction
