AIRankings world university AI rankings released

It’s the college entrance examination season again.

I remember that when I was taking the college entrance examination, there was such a popular saying.

That is, "Look at the school for undergraduates, and the major for graduate school."

There may not be anything wrong with this before I say it.

However, with the rapid development of science and technology in recent years, some majors related to front-end technology may start from the undergraduate level.

The most popular major at the moment is artificial intelligence.

Just recently, AIRankings released a ranking of AI-related majors in global universities.

Let’s take a look at which universities and institutions are on the list.

AI World Ranking: Top Three in Beiqing

AIRankings ranking combines research over the past ten years, as well as general artificial intelligence, computer vision, robotics, machine learning, natural language processing, and cognitive reasoning , multi-agent systems and simulation performance in these eight directions.

Carnegie Mellon University won the first place with a huge advantage. Peking University and Tsinghua University deservedly ranked among the top five in the world, ranking 2nd and 3rd respectively.

The University of California, Berkeley and the Massachusetts Institute of Technology followed closely, ranking 4th and 5th respectively, while the Chinese Academy of Sciences ranked 6th.

Qingbei/Beiqing, who "love and kill each other", are still very close in this ranking.

Judging from the revised number of AI papers, Peking University leads; while judging from the AI ​​index alone, Tsinghua University is slightly better.

However, after breaking down the various projects, we can find that the two schools have their own emphasis.

For example, Peking University scores higher in computer vision and natural language processing, and Tsinghua University performs well in general artificial intelligence and machine learning.

Other schools in the top 100 in the world are as follows:

##23 Shanghai Jiao Tong University469.7718.70##28##29##46Sun Yat-sen University309.968.40##50#5861##88City University of Hong Kong177.3710.3194西湖University167.74

In addition, from a national level, China’s AI research results can already rank second in the world, but there is still a big gap between the United States and the United States.

At the same time, the number of research institutions is also inferior to Germany, which ranks third, and the United Kingdom, which ranks fourth.

The specific performance is as follows:

Evaluation criteria

Overall, the ranking of this list The evaluation criteria are also very rigorous.

Among them, a total of six main areas of artificial intelligence are listed: computer vision, natural language processing, machine learning, cognitive reasoning, robots and multi-agent systems, plus general artificial intelligence and simulation. fields, with a total of eight directions.

At the same time, these fields are not isolated from each other, and there are many integrations between fields.

It is written in the evaluation details that when evaluating authors, each author will receive two points.

One of them is called Adjusted Publications (AP), which refers to the total number of revised publications by the author in a specific field.

This quantity is affected by two factors:

The first is where the article was published, which is reflected in the weight coefficient Pi of the above formula.

The second is to look at how many co-authors (excluding students) the article has. For example, if there are K co-authors, then each co-author will get K^{-1} points.

The other score is called the AI ​​index, which refers to the geometric mean of the number of articles published by the author in each field.

The calculation formula is:

where Si is the author's "AP" in a specific field, and n is the number of cross-fields.

The AI ​​index measures the breadth of the author’s research. The stronger the interdisciplinary ability, the higher the score.

People who have published articles in multiple AI fields will receive higher scores than people who have published the same number of articles in the same field.

When evaluating research institutions (including universities), the above two indicators will also be applied.

Adjusted Publications and AI Index.

The difference is that when calculating the total, articles published by all authors of the institution (including universities) will be included.

If an author finds another way out, the points belonging to him will also be transferred to the new institution.

AIRanking’s philosophy is simple:

To evaluate a school or institution is not based on how great your achievements have been in the past, but on how capable you are now.

Of course, this list is not necessarily the most authoritative.

At the end of the evaluation details, AIRankings pointed out some aspects and shortcomings that can be improved in this ranking:

First of all, AIRankings only collects data from academic research institutions and does not include Corporate-funded organizations.

However, not all AI results are published in specific AI journals and conferences. A considerable number of papers are published in multidisciplinary scientific journals (such as Cell, Nature, Science, etc.), and these papers are not included in the scoring.

In addition, AIRankings will distinguish the weights of different journals and conferences. Calculated based on their influence in the field.

This data is determined by consulting AI experts.

Ranking of Eight Major Directions

General Artificial Intelligence

## At first glance, this list is full of Chinese flags.

Four of the top five are from China, namely Tsinghua University, Chinese Academy of Sciences, Peking University, and Nanjing University.

There are also two Chinese universities selected from 6th to 10th. They are Shanghai Jiao Tong University ranked 6th and Zhejiang University ranked 7th.

It is worth mentioning that Tsinghua’s two indicators are both 326.33, far ahead.

Computer Vision

In the field of CV, four Chinese universities are still selected in the top ten.

Among the top five, Hong Kong Chinese Language School, Chinese Academy of Sciences and Peking University rank in the top three respectively.

It can be said that it dominates the list.

As far as this item is concerned, Tsinghua’s ranking dropped a few places. But it still ranked 9th, and the gap with 6th, 7th and 8th was not big.

Robotics

However, in terms of robot research, our country’s universities are much inferior. The top 50 schools are composed of three:

Tsinghua University ranks 39th, Hong Kong University of Science and Technology ranks 42nd, and Peking University ranks 50th.

Machine Learning

In the field of machine learning, Chinese universities are not particularly outstanding.

Among them, the top five are all occupied by American universities, and both indicators are very high.

Fortunately, Tsinghua University is unique and ranked 6th.

Peking University ranks 14th, NPU 21st, Zhejiang University 26th, Chinese Academy of Sciences 30th, and Nanjing University 42nd.

Compared with the direction of robots, the overall performance of machine learning is still much better.

Natural Language Processing

In the branch of natural language processing, Peking University deserves to be ranked first.

Peking University’s two scores were almost 40 points ahead of the second place. It can be said that the position is quite stable.

At the same time, Tsinghua University also entered the top five. The Chinese Academy of Sciences and Harbin Institute of Technology ranked 6th and 7th respectively.

Cognitive Reasoning

There are no Chinese universities in the top ten of this category.

There is still a certain gap between us and American universities in the branch of cognitive reasoning.

Peking University and Tsinghua University appear in more than 30 places on the list, ranking 34th and 38th respectively.

Multi-agent system

Unfortunately, there are still no Chinese universities in the top ten in this category.

Looking a little further, Tsinghua University ranks 13th. Judging from the scores, the gap with the 10th place is not big, and reaching the top ten is just around the corner.

The 55th, 57th and 58th places are Renmin University, Shandong University and Nanjing University respectively. All three schools have the potential to continue to occupy a place on this list.

Simulation

In the field of AI simulation, Zhejiang University stands out and ranks fourth. It is also the only Chinese university ranked in the top ten in this field.

In the subsequent rankings, Tsinghua University ranked 15th and Peking University ranked 21st. It's not that far away from the top ten.

In any case, there are still many universities in China that are among the best in AI subjects.

Students who want to enter artificial intelligence can do it now!
