1. What is the Internet of things

in fact, in a simple way, big data is to assist decision-making by analyzing and mining a full amount of non sampling data

the characteristics of big data

big data refers to the massive, high growth rate and diversified information capital that needs new data processing mode to collect, store, manage and analyze its content for the purpose of serving decision-making

big data has the following essential characteristics:

1. The fundamental purpose is to serve decision-making. Big data can help all kinds of organizations and indivials greatly improve their decision-making ability and make better decisions and judgments

Big data usually refers to the amount of data above 100t, which is difficult to be calculated effectively by traditional calculation methods, but must rely on new calculation methods and data mining tools

3. High frequency, big data is the data generated by user participation and interaction, according to the user's network traces to timely understand the user's relevant data, this kind of data is high-frequency data calculated by day or even hour. But the traditional data frequency is very low, many data are calculated by month or even by year

Big data is real-time data and can react in real time. For example, entering a keyword in the web search box can instantly present it, while the traditional data collection method is seriously lagging behind

5. Always online. Online is the precondition of big data. From this point of view, big data is always online and can be called at any time. By analyzing the traces of users on various network terminals, big data can better analyze users' behaviors, emotions, thoughts, hobbies and needs, so as to make better decisions and analysis

three key points of big data

first, the availability of data. At present, in China, the development of big data is seriously constrained by the lack of publicity of government information, a lot of data is difficult to obtain, leading to the difficulty of real big data mining and analysis, which requires the government to open more data in time to improve the availability of data

Secondly, the scientific model construction. The scientific nature of the model directly determines the quality of data analysis, which requires a high level of modeling, of course, the more data is concive to the reasonable construction of the model

Third, use experts to refine opinions. The original and high-quality viewpoint based on data mining, which provides the basis for decision-making, highly relies on high-quality data interpretation, which reflects the value of instry experts

2. For those that have come out and can be checked on the official website, this year's blockchain instry is more special. I think there are many shortlisted companies in the high tech Zone. Changsha Software Park Company has entered a blockchain project, which is called SMIC blockchain public service platform project. It has cooperated with Bank of Changsha and Dean justice, and now it is collecting enterprises to go on the chain.

3. At present, it is a bit difficult
in a word, blockchain is decentralized, using the trust protocol between distributed data nodes to achieve data sharing and mining upgrade. Artificial intelligence covers a wide range, including language recognition, image recognition, machine learning, intelligent logic and many other disciplines.

4. At present, the exchange rate between vnd and RMB is about 2600:1. You can exchange the money for 7 yuan and 23 cents. The price of a bowl of beef powder is not enough in some places..

5. The rise of every emerging technology is accompanied by so-called bubbles. When technology is mature and value is expressed, this argument will disappear in history, and regret a previous mistake (focus on the learning block chain).

6. Big data, artificial intelligence (AI) and blockchain are hot topics at present. These emerging technologies will change our future life all the time. So, for HR practitioners, what impact will these emerging technologies have on HR
big data
big data refers to the data set that can not be captured, managed and processed by conventional software tools within a certain period of time. It is a massive, high growth rate and diversified information asset that needs new processing mode to have stronger decision-making power, insight and process optimization ability
in the past, when recruiting personnel, it was first to establish a competency model based on theory. This model is based on certain experience, logic and hypothesis, and does not test whether it is really correct and effective in practice, but pays more attention to the logical inference before and after. However, the core of big data is to speculate what may happen in the future through massive data, rather than establishing causality. It comes from the summary of past practice. Google can be said to be the pioneer of employing big data technology. Google first let all employees complete a questionnaire with hundreds of questions, and then use big data analysis to get a set of mathematical model, so as to find the right talents according to the mathematical model. In this way, Google will not only judge the ability of job seekers based on their diplomas and grades, but also find those job seekers with great potential who are not good at school and grades

at present, big data is used in HR, mainly to digitize the behavior characteristics of the company's existing personnel, and to establish the competency model through big data and algorithms. The difficulty of application lies in how to conct data and how to establish mathematical model<
artificial intelligence, abbreviated as AI, is to study the law of human intelligence activities, construct artificial systems with certain intelligence, and study how to make the computer complete the work that needs human intelligence in the past, that is, to study the basic theory of how to use computer software and hardware to simulate some human intelligent behaviors Methods and techniques. For example, our common intelligent search is a kind of AI application
predictive algorithms and machine learning, as a tool to identify the best candidates, are emerging rapidly, and many AI + recruitment companies are emerging. By using AI to quickly evaluate the personal quality of job seekers, through the investigation of language preference, micro action, psychological emotion and social media language, the conclusion is drawn. You can also use AI tools to filter resumes and search in the database to save recruiters' time and sell jobs to qualified candidates automatically. AI recruitment software can be used in the early stage of recruitment to narrow the range of candidates. In the late stage of recruitment, employers often choose face-to-face communication and artificial judgment. This software improves the efficiency of recruitment and reces the bias of screening

at present, the application of AI in HR is mainly in the external recruitment software services, and the internal establishment of recruitment based on AI costs a lot
blockchain
blockchain is an encrypted general ledger of digital records, which are organized into a group of data, called "blocks", and distributed on a network. These blocks are located on the server and are called "nodes" that are chained together. Whenever a new transaction occurs, the blockchain will be authenticated on the network. Therefore, the authentication of each node is required to add the block to the chain. Blockchain creates trust because a of the chain showing each transaction is held by the entire network. It's a way to distribute data, only with the people you want to share it with, and the data can only be modified or deleted by its owner. It's encrypted, and it's almost impossible to change unless you're the validation owner of the data

the immutability and openness of information in blockchain make this data storage method very reliable. In the past, we need to spend a lot of time to verify the authenticity of ecation certificates, the effectiveness of skills, and even need to verify the relevant information through external background investigation agencies. Similarly, job seekers are reluctant to disclose personal information for fear of disclosure. Blockchain technology can help recruiters verify candidates' certificates in a highly secure way, rece the possibility of certificate being changed or forged, and effectively protect job seekers' information. In this way, we will rece the time of information verification and improve the efficiency of recruitment
at present, the application of blockchain is only a creation and conception. It requires a large number of people and organizations to participate in it. Only in this way can it be applied in the field of HR in the future.

"three bodies" although the living environment of the three body world described in the novel is extremely bad, the three body civilization is hundreds of years more advanced than the earth, and the earth is facing the risk of being colonized or eliminated. Although it is a novel, but the truth is simple, backward will be beaten, so how to quickly improve the level of science and technology

please click to enter the picture description

on the basis of artificial intelligence, big data and blockchain, we build a new architecture in which blockchain is the core and the underlying data base. Artificial intelligence and big data are built on the blockchain. Artificial intelligence is to identify the request of the other party's blockchain interaction activities. After identifying the activity type, it is handed over to big data for activity analysis and prediction. The results after the activity are obtained, and the conclusion whether it is possible to sign a contract with the other party is given. All the interaction information after signing the contract is recorded and stored through the blockchain, Subsequent blockchain interactions can be processed according to this contract, and there is no need for consensus processing of big data

application layer:

users use the new blockchain system through the application software to query their own blockchain account information, issue blockchain interaction tasks, and save interaction vouchers and results. The application layer needs to solve the problems of user identification and secure access

perception layer:

is realized by artificial intelligence technology. Its main function is to receive and identify tasks or data, judge whether it is necessary to request analysis or processing from the control layer, receive the feedback results from the control layer, and sign a contract with the other party's blockchain according to the results. The next interaction will be executed directly according to the contract. If the contract cannot be signed, it will be executed, The feedback results will be sent directly to the other party

8. There are many types of data. Now the data type is not only text form, but also image, video, audio, geographic information and other types of data, personalized data accounts for the absolute majority.

9. Just bring your ID card and residence booklet, and go to the exit and entry management center of the Public Security Bureau of the household registration office (where the staff will guide you to fill in the form).
the cost of passport processing is 200 yuan. You can get your passport within 15 working days at most. Your passport can also be sent to your designated address by express
