What is the concept and meaning of big data?

"Big data" is a data set with a particularly large volume and data categories, and such data sets cannot be captured, managed and processed by traditional database tools. "Big data" first refers to data volumes? Large refers to a large data set, usually in 10TB? However, in practical application, many enterprise users put multiple data sets together, which has formed PB-level data volume; Secondly, it refers to the large variety of data, which comes from a variety of data sources, and the types and formats of data are increasingly rich. It has broken through the previously defined structured data category, including semi-structured and unstructured data. Secondly, the speed of data processing is fast, and the real-time processing of data can be achieved even when the amount of data is huge. The last feature is the high authenticity of data. With the interest of new data sources such as social data, enterprise content, transaction and application data, the limitations of traditional data sources have been broken, and enterprises increasingly need effective information power to ensure their authenticity and security.

Data collection: ETL tools are responsible for extracting data from distributed and heterogeneous data sources, such as relational data and flat data files, into the temporary middle layer, cleaning, converting and integrating them, and finally loading them into data warehouses or data marts, which become the basis of online analysis and data mining.

Access to data: relational database, NOSQL, SQL, etc.

Infrastructure: Cloud storage, distributed file storage, etc.

Data processing: NLP (NaturalLanguageProcessing) is a subject that studies the language problems of human-computer interaction. The key to natural language processing is to make computers "understand" natural language, so natural language processing is also called NLU (NaturalLanguage Understanding), also known as Computational Linguistics. On the one hand, it is a branch of language information processing; on the other hand, it is one of the core topics of artificial intelligence.

Statistics: hypothesis test, significance test, variance analysis, correlation analysis, t-test, variance analysis, chi-square analysis, partial correlation analysis, distance analysis, regression analysis, simple regression analysis, multiple regression analysis, stepwise regression, regression prediction and residual analysis, ridge regression, logistic regression analysis, curve estimation, factor analysis, cluster analysis, principal component analysis, factor analysis, fast clustering method and clustering method

Data mining: Classification, Estimation, Prediction, affinity grouping or association rules, Clustering, Description and Visualization, complex data type mining (Text, Web, graphics, video, audio, etc.)

Prediction: prediction model, machine learning, modeling and simulation.

Results: Cloud computing, tag cloud, diagram, etc.

To understand the concept of big data, we should first start with "big", which refers to the data scale. Big data generally refers to the amount of data above 10TB(1TB=1024GB). Big data is different from massive data in the past, and its basic characteristics can be summarized by four V’s (Vol-ume, Variety, Value and Veloc-ity), namely, large volume, diversity, low value density and high speed.

First, the data volume is huge. From TB level to PB level.

Secondly, there are many types of data, such as weblogs, videos, pictures, geographical location information, and so on.

Third, the value density is low. Take video as an example. During continuous monitoring, the data that may be useful is only one or two seconds.

Fourthly, the processing speed is fast. 1 second law. This last point is also fundamentally different from the traditional data mining technology. Internet of Things, cloud computing, mobile Internet, Internet of Vehicles, mobile phones, tablets, PCs, and various sensors all over the globe are all data sources or ways of carrying them.

What is the Internet of Things AIoT?

AIoT intelligent internet of things is artificial intelligence internet of things. AIoT is the abbreviation of AI Artificial Intelligence and IoT Internet of Things. It is an artificial intelligence Internet of Things that collects a large amount of data from different dimensions through the Internet of Things and stores it in the cloud. Based on big data analysis and AI and other technologies, it realizes the digitalization and intelligence of everything. Artificial intelligence is a subject that studies how computers can simulate people’s thinking processes and intelligent behaviors. It is based on bionics, the improvement of algorithm model and calculation speed, and the commonality between human neurons and computer doors (doors are the basic unit of computers). Its strength lies in its learning, reasoning, thinking, planning and other abilities, which ordinary intelligent machines can’t do.

The embedded Internet of Things needs to learn a lot, so don’t learn the wrong route and content, which will lead to a salary failure!

Share a data package for free, almost over 150g. The learning content, face classics and projects are relatively new and complete! It is estimated that it will cost at least dozens to buy some fish.

The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected and interacted through various devices and technologies such as information sensors, radio frequency identification technology, global positioning system, infrared sensors, laser scanners, etc., and the collection of all kinds of required information such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., and the realization of ubiquitous connection, identification and management between things and people through various types of network access. Through this definition, we can feel that this will be a huge database, and the learning process of artificial intelligence also needs a lot of data information. Obviously, this is a link between artificial intelligence and the Internet of Things, which can link them together and play a greater role.

In short, the Internet of Things (IoT) uses terminals with different protocols to carry out information interaction and intelligent processing through a certain agreed protocol, while artificial intelligence can keep learning and become more and more intelligent with data. If artificial intelligence is software, it needs the Internet of Things as a carrier, and if it is hardware, it needs artificial intelligence to drive it. Therefore, we can also regard the Internet of Things as a carrier of artificial intelligence.

The Internet of Things is an important part of the new generation of information technology. The English name is "The Internet of things". Therefore, as the name implies, "the Internet of Things is the Internet of Things". This has two meanings. First, the core and foundation of the Internet of Things is still the Internet, which is the expansion and expansion network based on the Internet. Secondly, its clients expand and expand between any goods, and exchange and communicate information.

Hand handle teaching | B-end product manager resume writing guide (including professional speaking + multi-set virtual resume template)

Editing the Initiator: Most of the modules contained in your resume, but you have to write a good resume, but it is not so easy. So as the B-terminal product manager, how to write a highlight, and practical, can fully display your ability? In this article, the author sumizes a resume writing guide for the use of the B-terminating B-terminal product manager, and let’s take a look.

I. Introduction

The resume this thing sounds very simple, but it is difficult to write. Because thousands of people, everyone has their own preferences and understanding of resumes. This article is a summary of my individual’s resume on the B-terminal product manager, and many of whom have compared personal emotional color, so if you have different opinions, you can adjust it.

This article is mainly suitable for product manager reading, learning from B-terminal agency, learning from learning, not suitable for new people in the school, because I am not very familiar with the school, there is no saying, so new people Pay attention to reading when reading …

Second, the resume structure

I use the same structure in the three versions, but also similar to the commercial system of product managers on the market, a total of 5 large modules, as shown below:

Many people will entangle whether to write self-evaluation, my suggestion is to write, self-evaluation is a key module in your resume, you should reflect your highlight in this place, concentrate the essence, not to let the interviewer work and work and Exploition in the project experience.

Some people will put this module in the end, my suggestion is in front, this is the same as "the words" in the "Pyramid Principle", first out of the show, it is right.

Basic information This piece is basically less than going to turn, but some details need to be noted that I have marked, such as gender, age, working years, job hunting, these needs to be carefully checked.

Next, let’s take a look at the basic information I wrote in the virtual resume I wrote. This resume is written in MarkDown, so I use a table mode to renderate the layout of this fragmentation.

The resume owner is "Mai Feifei" and "Mai Xiaofei", which refers to the product manager for more than 5 years, respectively, and the overall structure of the resume. It is only some experience and personal highlights. It will be different.

Basic information of Mai Feifei

Basic information of Mai Xiaofei

Self-evaluation is a wave of king bombings, don’t write some "lively, optimism, hard work, high conscious, strong implementation ability, and brave enough to accept new challenges", you have to pinch this piece, The words are said to pick out the contents.

For B-terminal product managers, I suggested to write from big to small structures. That is to write from the industry / company, then the project / department, and finally go to the individual’s hierarchy, so that the HR or interviewer is more inseparable, it also meets the MECE principle, more structural.

Mai Fei’s self-evaluation

Mai Xiaofei’s self-evaluation

Some of the self-evaluation in the picture may be very long because I deliberately wrote some introductors to do some inspiration. Everyone pays attention to the reduction, control space and text density when writing. If you have other bright spots or additional to add, you can also put it here, such as some excellent works, awards or very matched jobs.

Work experience is my longest module because simple write work experience is very simple, but it is necessary to put out the things and grades made in a company, but also the content of virtual creation, it is too difficult to me.

Work experience is highlighted,What is the main thing to do, then make any achievements?. If some content is not very easy to write, then refine some keywords, used to match the job description in the recruitment information, try to let HR see you have done this piece.

There is dry goods to write dry goods, there is no dry goods, you can write keywords, or you can bold keywords and increase visual implies.

Mai Fei’s work experience

Whether this module is to add "Company introduction" and "work performance", I asked some friends, everyone is not the same, so I have two versions, everyone compares to see if I want to choose one Content. I can’t write two versions, write multiple resumes, cross-type delivery, see which effect is good.

Mai boats work experience personal recommendations work experience and project experience can write separately, more work is to look at your past experience to be what the company until how long, what about outstanding contributions; and whether the project experience is emphasized and job requirements match the value which items you have done in the past, experience and current job whether these projects need is match fit, and have not done any items from 0-1, if there is enough experience and richness so on.

Project experience resume is the second most important content, I think it is the first "self-evaluation."

To experience it is difficult to write the project, because the project is too eat this stuff up vertical experience, and many people experience in the project will increase the realism write some data, but this can easily be caught little mistake during the interview, if the data not familiar with the blind or made, impact on the interview is still getting bigger.

STAR project experience are generally used to write the law, the truth is easier said than done, I sometimes not very good grasp. Because some projects may not have the results, or achievements expressed some projects are fundamentally bad.

Mai Feifei project experience 1

Mai Feifei project experience 2

About STAR project experience is the law of writing, there are many variants, so I wrote two templates, we can compare and see in the end what is more appropriate.

Mai boats of project experience 1

Mai boats of project experience 2

About project experience this piece, I wrote a long time to find a lot of resumes learn from this content piece, and found that in fact a lot of people are content to write the contents of specialized jargon or words of surgery. Read up on the feeling I did not say to what point, but the actual viewing resume when it seems not affect my subjective feelings on this resume.

A small amount of jargon explained resume appears, in fact, does not affect how I feel about the whole resume, as long as you can pass in place some key words, other innocuous content will not look at your resume when a closer look.

End of the article I will put some jargon and terminology of my collection, there are times when nothing resume writing, or what there is no inspiration, they can learn from it.

In view of space reasons, I suggest that educational experience and credentials can be combined together to write, if you experience a lot of education, there are many certificate, and then it split into two modules is also possible.

This piece of content will basically not overturned, a point to note is that the issue of education. Sometimes the company will first pay greater attention to education, so it is best marked on the resume that he is full-time or part-time. Frank, it could reduce HR and the interviewer resume screening of trouble, but also disguised himself saves time.

Third, the supplemental content

Cliches is good, but still have to pay attention to control the tempo and length, do not write too many false big empty of content. The following excerpts from the network, part of my own finishing.
