Computing power of big data algorithm
to define big data, we can define it from the following three aspects:
first, big data redefines the value of data. Big data represents not only technology, but also an instry and a development trend. Big data technology refers to a series of related technologies around data value, including data collection, storage, security, analysis, presentation, etc; Big data instry refers to the instrial ecology based on big data technology. At present, the instrial ecology of big data is not perfect, and there is still a large space for development; Development trend means that big data will become an important innovation field
Second, big data has laid the foundation for an intelligent society. The development of artificial intelligence needs three foundations, namely data, computing power and algorithm, so big data is of great significance to the development of artificial intelligence. At present, in the field of artificial intelligence, the application effect has been improved obviously, one of the important reasons is that there are a lot of data support, which will comprehensively promote the training process and verification process of the algorithm, so as to improve the application effect of the algorithm
thirdly, big data promotes the digitalization of social resources. The development of big data makes data proce greater value. This process will greatly promote the digitalization process of social resources. After more social resources are digitalized, the functional boundary of big data will be constantly expanded, thus driving a series of innovations based on big data
finally, one of the important reasons why big data is important is that big data has opened up a new value field, and big data will graally become an important proction material. It can even be said that big data will be an emerging energy in the intelligent society.
bitcoin came into being with the financial crisis in 2008. It was proposed by a Japanese who called himself "Nakamoto Tsui". According to a specific algorithm, the electronic virtual currency generated by a large number of calculations is composed of a series of complex codes generated by a computer. The new bitcoin is manufactured through a preset program. With the increase of the total amount of bitcoin, the speed of new coin manufacturing slowed down until 2140, when it reached the maximum amount of 21 million. So far, the total amount of bitcoin excavated has exceeded 12 million
the biggest advantage of bitcoin is that it is decentralized, gets rid of the constraints of third-party institutions, will not be artificially manipulated, and the total amount is fixed. It can circulate globally, and completely gets rid of the government's intervention in currency. Moreover, some businesses of American e-commerce companies such as eBay and Uber have begun to support bitcoin payment, and a few domestic businesses have also supported bitcoin transactions
as you may see, it's still foggy here. In fact, it's easy to understand that bitcoin is a kind of currency, virtual currency. Just like the currency in online games, payment can only be made in the specific environment allowed. Another example is q-coin, which can't be used to buy vegetables, clothes or cosmetics, but can be used to buy some Tencent procts with similar properties. But the difference is that bitcoin can not be created by any organization, and will not be artificially priced and manipulated
therefore, the greatest attention should be focused on who can approve this currency, or which merchant allows you to buy his goods with bitcoin. To put it more simply, businesses sell you goods, then charge you RMB, and then use the RMB to spend in other places. But if they charge you bitcoin, and they can't spend in other places with bitcoin, then businesses will definitely not sell you things, which leads to the lack of liquidity of bitcoin
although many governments have not explicitly banned bitcoin, no country has explicitly stated that bitcoin will be regarded as a legal currency. Under the special national conditions of our country, it is impossible to recognize this kind of currency even in the future, so bitcoin has no real value, only the virtual value given by people, which determines that there is no market for bitcoin in the future
and at present, there are very few people investing in bitcoin in China. Basically, this kind of investment is pure speculation. If it is mped in the hands of a limited number of investors, it will become rubbish. Similar to MLM, the people in front have meat to eat, and the people behind have no porridge to drink<
now the central bank has entered the three major bitcoin trading platforms for inspection, and the intention is very clear: I don't explicitly ban this currency, because I need to follow the international and open route, and developed countries have not banned it, so I can't help it, but I firmly don't agree with its existence, so I have to take action to combat it! Therefore, in the end, the author suggests that we should try our best not to invest in such worthless things.

the denominations of hujihua series (1967-1976), bird series (1976-1980), boat series (1985-1999) and portrait series (1999 -) were 2 yuan, 5 yuan and 10 yuan, and the plastic version was released in 2006
In fact, Huji flower is an orchid, but in Southeast Asia, people have been using the term "Huji flower" by convention, and Huji flower (Zhuojin wandelan) is also the national flower of Singapore. Huji flower was originally a wild plant in the mountains, but also one of the rare graceful flowersin the middle ages of Europe, there were almost no portraits on coins. Later, with the rise and development of the Renaissance, portraits reappeared on coins. It first appeared in Italy, and then monarchs followed suit. Nowadays, most countries in the world mainly print their heads on paper money, but some countries still have portraits on their coins.
