The word "culture": its appearance in China can be traced back to the Western Han Dynasty. "Culture" is not only a system of civilizing and educating, but also a system of rites and music. This understanding has been maintained in our country until modern times. The meaning of the word "culture" that we use today is obviously different from that of ancient times. It was introduced from the west through Japanese translation at the end of the 19th century. At that time, there was no definition of the word, and people only used the word "culture" according to their own understanding and needs. According to analysis, there were about three meanings at that time; First, it is synonymous with "civilization"; Second, in a broad sense, it includes spiritual and "civilization" contents; Three, narrow sense, refers to the spiritual content. To this day. The meaning of culture is broader; There are also many people who agree that culture refers to "ideology", and everything outside politics and economy is among them; Others make a broader understanding that everything created by human beings (that is, the integration of material civilization and spiritual civilization) is culture; Besides, some people have other explanations.

In view of the fact that scholars at home and abroad have different opinions on the concept of "culture", it has been suggested that the word "culture" may be a vague concept naturally, and it is difficult to make a clear and complete definition. Instead of pursuing a simple and precise definition, people should determine a flexible range from the perspective of set.

Although there are many definitions of culture, I personally think that it should be the same in many aspects, and we can roughly summarize it into the following three aspects;

First, ideology (also known as ideology) means people’s world outlook, way of thinking, religious beliefs, psychological characteristics, values, moral standards, cognitive ability and so on.

Second, the way of life, that is, people’s attitude towards their food, clothing, housing and transportation, marriage, birth, illness, family life and social production activities, and some forms taken in these aspects.

Third, spiritual materialized products, that is, from the formal point of view, are some material things, but through the material form, they can reflect people’s differences and changes in ideas.

From the above three parts, the scope of culture is basically outlined. But we should pay attention to: the word culture; It should be an organic whole, which is not only the simple addition of the contents of these three parts, but also the mutual influence and premise of the contents of these three parts, and should be organically combined according to a specific sequence.

On April 23rd, Beijing time, the 76ers beat the Nets 96-88 in the NBA playoffs.

I am not that kind of naive person, and I am not that kind of person who just-I will listen to advice and make sacrifices for the team’s better performance. "

Golfers, what do you think of the promotion of the 76ers? Welcome to leave a message!

CVPR 2023, one of the top three computer vision conferences, was exposed in the paper of China Smart Car Company.

Domestic autonomous driving companyHao mo zhi hangThe paper Bev-Lane Det: A Simple and Effective 3D Lane Detection Baseline submitted by the technical team of its Artificial Intelligence Center was successfully selected into CVPR2023.

What problems should the new research solve?

3D lane detectionAs a hot topic in the field of automatic driving, it plays a vital role in vehicle routing. In the past, related technologies were often difficult to be applied because of its complex spatial transformation and inflexible representation of 3D lanes.

Faced with these problems, Millie independently developed an efficient and robust monocular 3D lane detection, referred to as:BEV-LaneDet.

In BEV-LaneDet, Millimeter team first converted all the internal and external parameters of the input image into unified internal and external parameters through the virtual camera, which ensured the consistency of the spatial relationship of the front cameras in different vehicles and effectively promoted the learning process.

Moreover, Millimeter Team uses feature extractor to extract the features of the front view image, and proposes a simple but effective 3D lane representation, which is called "Key-Points Representation". This module is more suitable for representing complex and diverse 3D lane structures.

On this basis, inspired by FPN, Millicent team also designed a lightweight and chip-friendly spatial transformation module called "Spatial Transformation Pyramid", which is a fast multi-scale spatial transformation module based on VPN, mainly responsible for the transformation from front view features to BEV features.

Finally, the team predicted the lane on the plane tangent to the local road surface, divided the local road surface into s1×s2 grids, predicted confidence, embedding for clustering, lateral error offset and the height of each grid, and used fast clustering method to fuse the results of each branch in reasoning to obtain 3D lanes.

How did BEV-LaneDet perform?

Through the above methods, the F1-S?core of BEV-LaneDet can reach 185FPS on the OpenLane dataset, which is 10.6% higher than the current SOTA.

BEV-LaneDet can also lead the current SOTA method by 4.0% in the performance of Apollo 3D Lane Synthetic.

At present, Mimo Zhixing is the first echelon player in domestic self-driving mass production, and the paper written by its technical team BEV-LaneDet was selected for CVPR, which is actually the embodiment of the technical strength behind the commercial progress.

At present, HPilot has iterated three generations of products, and has achieved mass production on nearly 20 models of Wei brand, tank, Haval, Euler, Great Wall Gun and other brands. In the future, passenger cars equipped with Millimeter-assisted driving products will reach millions of orders of magnitude. As of February 2023, the mileage of user-assisted driving has exceeded 35 million kilometers. NOH, the first city in China that can land on a large scale, has also reached the delivery status with its software sealed.

In addition, the terminal logistics automatic delivery vehicle has initially completed the commercial closed loop, delivering more than 1,000 units, and the delivery order volume of the terminal logistics automatic delivery vehicle Little Magic Camel series has also exceeded 160,000, and the commercialization process is accelerating in an all-round way.

Introduction to CVPR

IEEE (Institute of Electrical and Electronics Engineers) CVPR (Conference on Computer Vision and Pattern Recognition) is one of the three top conferences in the field of computer vision and pattern recognition.

The main content of the conference is computer vision and pattern recognition technology. CVPR is the world’s top computer vision conference (one of the three top conferences, the other two are ICCV and ECCV). In recent years, there are about 1,500 participants every year, and the number of papers collected is generally about 300.

CVPR has strict employment standards. According to CVPR officials, CVPR2023 received a total of 9,155 papers, a record high, and the organizing committee finally hired 2,360 papers, with an acceptance rate of 25.78%.

CVPR is also the witness of major changes in the field of AI vision. The current wave of AI driven by deep learning originated from Hinton’s blockbuster in CVPR Challenge.

Based on ToF depth data, the AI algorithm expert model data deep learning network can complete the accurate recognition of human postures such as falling, sitting, lying and walking. Intelligent ai behavior recognition monitoring can monitor the abnormal behavior of personnel online, deeply analyze the obtained video information according to the AI behavior detection algorithm, and trigger alarm information immediately when the behavior of personnel does not meet the requirements of the rules. Automatic recognition of employees’ actions and behaviors in relevant work areas can realize fatigue recognition and departure recognition in actual scenes.

Different from wearable monitoring equipment and camera monitoring equipment, the company’s smart pension facilities provide non-touch monitoring for the elderly, which is more convenient to use without the elderly actively cooperating with wearing and charging the facilities regularly. The escalator personnel fall detection algorithm can accurately identify the behaviors of luggage case, trolleys, strollers and their personnel on the escalator, such as falling, queue density, retrograde, etc., and help managers find dangerous situations at the first time. The development of sensors makes objects have touch, smell, vision, taste and hearing similar to human beings, and makes objects come alive, which is an important means for intelligent products to interact with the outside world.

Smart power series algorithms realize intelligent monitoring, real-time analysis and hidden danger alarm for personnel unsafe behaviors, environmental risks, facilities and other parameters, and create an innovative mode of power safety production. Equipped with edge gateway box, embedded with AI Eye-in-the-Eye algorithm, it can also provide early warning information for intelligent and diverse emergencies, such as campus personnel gathering, personnel falling identification, dangerous area intrusion identification, high climbing identification, etc., and protect students’ personal safety in school.

Analyze people’s numerous behaviors and combine them with relevant fixed scenes to obtain user data analysis, such as decomposing the actual operation links of workers, establishing standardized data rules in terms of time and action standards, setting up multi-scene coverage video surveillance system at the entrance and exit of escalators and taking the escalator area, and analyzing the artificial intelligence algorithm with "smart brain". It can quickly and accurately detect violations such as passengers falling down, the escalator on the stroller, the detention at the entrance and exit of the escalator, passengers retrograde, and the body reaching out of the escalator, and prevent them as early as possible by means of voice broadcast and sending early warning information to the management unit, effectively preventing accidents caused by people’s unsafe hidden dangers.

The recognition technology of body movement behavior in artificial intelligence image processing algorithm also plays an important role in intelligent monitoring. In the process of visual tracking, the target tracking is realized according to the correlation algorithm of adjacent frames or through the global correlation algorithm of quality inspection of all frames. Real-time tracking of body movements by video has high efficiency and low cost.

Personal behavior analysis mainly includes human face recognition, staff behavior recognition, range intrusion detection, inspection of items left behind, crowd gathering recognition, intelligent tracking and so on. Relying on the sensor built in the helmet and the field camera, it can automatically identify the behavior of people falling in the construction site, rescue them as early as possible, improve the effect of manual supervision and ensure life safety. Personnel fall to the identification alarm system. The personnel fall detection system reduces the risk of on-site personnel monitoring and improves management efficiency.

The fall detection system effectively remedies the shortcomings of traditional methods and technologies, improves the effect of manual supervision and ensures life safety. Fall into the detection and identification system for humanized care and intelligent operation management, reducing costs, reducing risks and improving management efficiency for the elderly. The identification of AI video content is mainly aimed at the automatic identification, classification and prediction of the behavior of the target characters in the picture. According to the motion information captured by the camera, the human posture and motion trajectory are calculated according to the information data by the algorithm.

Since ChatGPT swept the world, companies have opened their wallets to explore this technology, and the field of artificial intelligence has set off a new wave of enthusiasm. It has also attracted people’s attention to GPT-3 of OpenAI, which is a large language model (LLM) behind phenomenal ChatGPT, and it provides similar human responses to queries.

However, the hardware for training code (mainly NVIDIA GPU) is in short supply and expensive, or only companies with strong financial resources can use it. However, Pittsburgh Supercomputing Center hopes to provide researchers with free access to the world’s largest chip to run the Transformers model. Microsoft has applied GPT-3 to AI technology in Bing search engine.

The Supercomputing Center (PSC) of Carnegie Mellon University and Pittsburgh University is launching a new round of access to the CS-2 system of Cerebras, which is widely used to train large-scale language models. CS-2 is the AI accelerator in the Neocortex supercomputing system of PSC.

CS-2 has a wafer-scale engine chip of Cerebras, which is considered to be the largest chip in the world with 850,000 cores. The chip is used in artificial intelligence (AI) and traditional supercomputing (such as the decarbonization project used in the National Energy Technology Laboratory), which provides more accurate results through logical calculation.

PSC welcomes high-performance computing projects mainly related to artificial intelligence and machine learning workload, but it is not popular with traditional high-performance computing applications. The project encourages applications to adopt AI algorithm to run traditional HPC workloads. These proposals must be non-patented and can only come from American research institutions or non-profit organizations.

In addition to GPT-3, CS-2 system also supports the popular BERT Transformers model.

Andrew Feldman, CEO of Cerebras Systems, said: "There is a lot of discussion about large language models and very large language models. However, after a given scale (for example, 13 billion parameters), the number of organizations that actually train a language model from scratch is very small. Because you need to solve a lot of hardware problems first. "

Generally, running the Transformers model requires a lot of data, data science knowledge and deep machine learning expertise. Training data takes several weeks, and hardware options include GPU and TPU(GPU is used by Microsoft for Bing and AI, while TPU is used by Google for Bard chat bots).

Neocortex of PSC has been used to study artificial intelligence in the fields of biotechnology, cosmic vision map and health science. The system is also used to study the method of deploying AI on the new memory model deployed in CS-2.

Cerebras’ WSE-2 chip in CS-2 contains 2.6 trillion transistors, and all related AI hardware is concentrated in a chip size. The system has 40GB SRAM on-chip memory, 20 PB bandwidth per second and 12 100Gigabit Ethernet ports. CS-2 is connected to HPE’s SuperdomeFlex system, which has 32 Intel XeonPlatinum 8280L chips, each with 28 cores, and the running frequency is as high as 4GHz.

In contrast, NVIDIA GPUs are usually distributed on many systems. Nvidia’s GPU relies on CUDA parallel programming toolkit, which is widely used to study artificial intelligence. Feldman: "I think we have a great chance to replace GPU and TPU and do it in a more effective way-achieve better goals with fewer mistakes."

The demand for ChatGPT has overwhelmed the OpenAI system, so the demand for AI computing will be overwhelming in the future.

Jin Hyundai said,The company has applied NLP (Natural Language Processing), OCR (Optical Character Recognition) and image recognition technologies in some software systems.At present, the specific application scenarios include:1) Automatic labeling of cadre evaluation.NLP technology is used to label all kinds of documents and materials of cadre evaluation automatically, which breaks through the integration of text multi-classification, semantic recognition and rule engine, and the accuracy of labeling is over 95%, which is completely practical.2) Intelligent search of knowledge base documents.Based on NLP technology, word segmentation, entity recognition and text similarity processing are carried out for document titles and contents, and a labeling system is established to label all documents. Under the traditional search strategy of text matching and sorting, intelligent search based on tags and semantic network is realized, and the accuracy of search results is greatly improved, which is closer to the needs of users.3) Text extraction of biomedical equipment report.Using OCR technology, the experimental reports of biomedical equipment (editable PDF and scanned PDF, etc.) are accurately extracted, which avoids the problems of low efficiency and error-prone caused by manual copying, and solves the problems of small font recognition and table breakage recognition.4) Image recognition of live equipment.OCR technology is used to identify and extract the instrument and interface data of power equipment, which greatly improves the efficiency of manual inspection. Compared with the general OCR model, it further solves the problems of identifying special characters (such as ω, μ) in the power field.5) Intelligent pre-examination of project data.Using image recognition and OCR technology, the key information of the project can be automatically recognized from the paper report image, and seals and signatures of different colors, shapes and sizes can be recognized at the same time. With the company’s further research on artificial intelligence technology and the implementation of measures such as the company’s access to Baidu Wenxin Yiyan, the company will have more and more research results and application scenarios in the field of artificial intelligence in the future. At present, similar products of MOSS are not involved.

At present, the Chengdu World Table Tennis Championships, which has attracted the attention of table tennis fans all over the world, has decided the final king. China Guoping, the king of the world table tennis world, won the championship of men’s team and women’s team without accident. This result is also the embodiment of Guoping’s top strength. However, although the champion belongs to Guoping, for some defeated players of Guoping, they have to find something else to show their unconvinced. No, Japanese table tennis, which has been suppressed by national table tennis, came back to China, and the Japanese media released a list of male table tennis players in the World Table Tennis Championships. Funny thing is, in this list, Malone, who won all seven games in the World Table Tennis Championships, was directly ranked fourth. At present, Fan Zhendong, which ranks first in the world, is directly ignored by the Japanese media, and can’t even enter the top five. As for the number one player, I believe you should have guessed it.

Chengdu World Table Tennis Championships, as a major competition this season, almost all the top table tennis players in the world came to Chengdu to participate in this table tennis feast. As the host country and the top table tennis team in the world, Guoping is naturally the favorite of the champion. However, neither the men’s team nor the women’s team let the fans down. In their own home court, Guoping won two championships in a sweeping way. Of course, compared with the women’s team, there are still some waves in the men’s team’s championship.

In the semi-final with the Japanese men’s team, the China men’s team encountered the biggest challenge since the start of the game. Japan’s first brother, Chinese-American Zhang Benzhi, is in very good shape in this World Table Tennis Championships, especially in this Sino-Japanese table tennis semi-final. In order to test Wang Chuqin, the national table tennis coaching staff arranged for Wang Chuqin to serve as the second single against Zhang Benzhihe. Wang Chuqin, like Zhang Benzhihe, is a post-00 player, which can also be regarded as a confrontation between new forces in the future table tennis world. But what I didn’t expect was that Wang Chuqin lost completely in this post-00 showdown.

If Wang Chuqin’s loss is understandable, then the number one player in the world, the key player of China team, the loss of a single Fan Zhendong made the fans feel nervous. In the face of Zhang Benzhihe, Fan Zhendong lost his former swagger and was defeated by Zhang Benzhihe. In the end, although Guoping still relied on its overall strength, it eliminated the Japanese team and advanced to the final. However, this five-game game still made many fans sigh: Fortunately, there is only one Japanese team, Zhang Benzhi and He.

It was Zhang Benzhihe’s performance that completely stunned the Japanese media after the game. After the World Table Tennis Championships, the Japanese media "Tokyo Satellite TV" produced a ranking of men’s table tennis strength in the World Table Tennis Championships. To tell you the truth, this ranking is a bit interesting. He is convinced of the players’ victory in the World Table Tennis Championships as a basis for ranking. In other words, whoever wins more games will be in the top position. That’s right, there is such a funny situation. No one of the main players in table tennis can enter the top three. After all, the seven wins of seven battles, which are as strong as Malone’s, can only be ranked fourth because of too few wins. Fan Zhendong, the number one in the world, can’t even get into the top five in this ranking.

Not surprisingly, in this ranking, the number one player in Japan’s team is naturally Zhang Benzhi and He. He ranked first with 11 wins and 1 loss, and was called the strongest men’s singles player in this World Table Tennis Championships. The second place is Huang Zhen Ting, a Hong Kong player from China who scored 8 wins and 3 losses. The third place is Qiu Dang from Germany, whose record is 8 wins and 4 losses.

To be honest, this ranking is totally unreasonable. After all, because of the strength of national table tennis, all the five main players have strong strength, basically taking turns to play. In this way, Malone’s chances of playing will naturally be less. However, Malone only played seven games, but he won all. Just because he played a few games less than Zhang Benzhi, is he weaker than Zhang Benzhi in strength? It can only be said that this is just the self-satisfaction of the Japanese media, which specially found an angle that is beneficial to Japanese players to make such a ranking. However, it is difficult for them to think of such an angle.

A wave of 1500 people were organized before the activities of Alibaba Cloud servers, and 200 people were organized. But I am not organized now.

But when organizing this activity, I learned that everyone has a common question:Is this server use? ?

When it comes to the server, many people may say distributed, do calculation, crawl, and procedure background service, multi-person cooperation, etc.

In fact, these ordinary people can not use it, I will say that everyone can use it.

Everyone must have a work folder when you work, the students are your own courseware, exam, prepare for interview, and so on.

The friend who has already worked, there will be a file that puts your own important document, MarkDown, Pictures, Resume, etc.

Such an important folder, and we have to update every day, and we are worried about the computer is lost, or it is broken, suddenly these are not seen.

So we want to back up.

There is also our frequent personal computers and working computers to synchronize some private information, rather than passing on WeChat.

These are the use scenarios of Git private service, and it is very easy to use.

Everyone also knows GitHub, Gitee can also engage in private warehouses to back up, synchronous files, but their documents may put a lot of important information, including their own passwords, key classes, and put it above. It is not necessarily safe. You are not afraid of which major bugs will leak your information [wit]

More crossed, GitHub and Gitee are speed-off. After all, the functional positioning of people is not a network disk.

There is a large file in the project (more than a few hundred m), such as PDF, PPT, etc. It will make you suffocate.

Later, I will send a document to tell, how do you have a git private service!

This can be used to generate a download link of the file, or the local file can also be transmitted to the server.

It is equivalent to making an object store, in fact, cloud manufacturers also have objects stored.

However, we can do one, not enough, very classmates, you should not know how object storage, in fact, we can use the server to be a similar company.

I have been deployed on the server with a tool written by Go now. Used to pass files with the server, or create a temporary download link for some files.

These are direct command lines,

In this way, I wrap the command package into a shell command, want to pass the file, directly uploadTomyServer, and then return to the downloadable link, this file also passed to my server.

I also put my project code on GitHub:

Interested exciting friends can go to learn a wave, and give a star. Haha.

Do a website, for example, everyone knows how to write a few lines of code with HTML, but how to show someone else?

If you use your own computer to do a server, you can only access your website with your device in the same router, and this device can not have your website.

Because your IP is not a public IP.

If there is a cloud server, it is a public network IP, your website can make anyone visit.

Or a service you provide allows anyone to use.

For example, in the second example, we can develop a file storage, this service, I only put the command line to others, others can use my service to generate a link, of course their files have passed to me. On the server.

Again a way of use.

I have previously organized the activities of the server, Ali Cloud gave me an Excel, let the face are the list of friends who buy servers here, I will directly put this list directly to the group, let everyone check, appear in list You can find me to cash back, do you have anything.

There are several big problems that do this:

• Everyone is going to download Excel, do contrast, there will be someone to change the content of Excel and then say it is bought from you, I can’t make a comparison with Excel.
• Excel has a personal information from others, which is unstoppable.
• If everyone uses Excel inquiry, private letter I cash back, one is nearly two thousand people to find me cash back, my WeChat is imposed, this becomes physical activity.

How should I do it?

I simply write a query page, the backend logic is to read an Execl form, everyone enters her Ali Cloud ID in the query page, if in Excel, the page will return the QR code of the cash back group, everyone can be independent Scan code is plus group.

In this way, I will finally send an equal red envelope directly in the cash group, is it great to reduce human cost?

Of course, I generated the QR code of 17 cash back groups. According to certain rules, they show friends passing through the query.

It is such a very ordinary query page.

After the query passes, the cash back group is displayed.

But to deploy on the server, because there is no public network IP, others can’t use your service.

Learn Linux

Learning Linux actually engaged in a virtual machine on your computer, or you can also learn the dual system, but this is very testing how your computer performance is.

If you have a server, it is a separate computer. How do you Hoho Huoho, and you don’t have to shut down a year, you can always run your task, and your local computer is completely isolated.

More convenient, you are now in the system, such as Centos, want to do an experiment, need to be on the unbantu, if it is a cloud server, the replacement system is in the background point, one button is reloaded, the cloud manufacturer basically supports all the system installation of.

We usually play Linux is often equipped with various environments, then this Linux is played by yourself (generally unwarring use root permission), in short, the environment is unable to reload, basically reload.

The cloud server reloading the system is too convenient.

There is also an environment where you are not easy to match. If you play this environment later, you will go back to this previously matching environment rather than re-fitting the system.

Then you can save the function with the cloud server, you can play a mirror package in the moment you match the environment. If the environment is broken, you will fall back to the status of the last mirror package. This is very fragrant.

Summarize

In fact, there are still many other uses, but I just say that everyone is universally used.

The above, the three points mentioned: git private service, document storage service, build a website, I will send a hand to do your hand, truly use the server to improve our work learning efficiency!

Regarding the activities of the free collar server, I will not organize so many people also involve the cash back. Some of the friends do not look at the group information, then directly private letter and I complain, I am really handling, body and mind Too much.

If you want to buy a server, you can purchase this link:

Https://www.aliyun.com/minisite/goods?taskpkg=1111ydsrwb&pkgsid=1959&recordid=962642&usercode=roof0wob

Now is the double eleven event, or the activity price is over, and it will be over in December.

The price is really very cheap now, 60 blocks for new users can buy one year,But I will no longer be cash out, everyone can buy it yourself through the link..

If you want to register a new number, pay attention to real-name certification requires a new ID card.

It is recommended to buy these two servers, which is all, cost-effective.
