Riding the wind of rebirth

Chapter 1906: Making Research Romantic

It took nearly an hour to finish all this. Zhou Zhi was too lazy to go back to the bedroom. As usual, he just fell on the big couch next to his seat and was done.

In the next two days, Zhou Zhi took Mai Xiaomiao to familiarize themselves with the oracle bone splicing project and the graph database architecture of the digital library.

These two projects will also be the focus of future experimental research on cellular neural networks.

The oracle bone splicing project originated from the automatic recognition technology of converting image characters into vector characters in the Hanwen large character library, as well as the root deconstruction and splicing technology. The success of these two sub-projects also saved a lot of time for the research and development of the Hanwen large character library, especially the second and third phase projects. Almost after getting the "Sea of ​​Characters" cards of the two senior brothers, the recognition, input, vectorization, and warehousing were completed in a very short time.

Due to the extremely rapid enrichment of the second-phase character library, the possibility of Chinese character-using areas such as Hong Kong Island, New Zealand Island, Taiwan Island and even island countries to independently develop full-code character libraries was directly blocked, which attracted Japan and South Korea to send working groups to "join in the event", and finally made the Hanwen large character library the world's only and unified Chinese language character large character library.

These technologies will certainly not be shelved after the development of the large character library is completed, but will continue to be deepened and developed. Soon Zhou Zhi found another application scenario for them, which is oracle bone splicing.

Therefore, the two previous technologies have developed into the edge recognition matching algorithm and the variable root matching algorithm.

These two algorithms are simple to say, they just realize some of the functions of the human eye and brain.

The former algorithm allows the computer to identify the edge features of the fragments in the image regardless of their size, position, or angle, and match them with the edge features of other fragments in the database. If a matching position is found, it will try to piece together the oracle bones.

After the oracle bones are pieced together, the text on them often changes from a few scattered words of unknown meaning into a paragraph, and a lot of historical information hidden in the fragments will be presented to researchers for the first time.

The value is of course self-evident.

The second algorithm is more discrete and nonlinear.

Although oracle bone script is already very mature, it has been popular for a very long time and there is no fixed structure when forming characters. Therefore, there are often dozens of ways to write a character.

For example, "bu" is actually a radical of left foot and right foot. There are many ways to write these two radicals, some complex and some simple. After these two radicals were carved on oracle bones by the diviners and combined into the character "bu", their positional and angular relationships were varied.

For trained humans, as long as these two roots are carved roughly the same, the concept will naturally emerge in their minds: this is the left foot, and this is the right foot.

Then, as long as the two roots are placed together and roughly staggered up and down, another concept will naturally pop up in the mind: Well, this is most likely the word "step". However, such thinking activities are too "advanced" for current computer technology, because current computer technology is still mainly processing linear logic operations, and it is difficult to handle such complex nonlinear relationships where one input has multiple outputs, or multiple outputs together lead to one input.

The subject that Mai Xiaomiao studies is used to solve this problem.

In a broader sense, this is the direction of artificial intelligence. In a narrower sense, this is a preliminary attempt to allow computers to solve nonlinear problems.

Of course, mathematical theories and tools alone are useless in solving practical problems. If you want to integrate such a complex project as oracle bone inscriptions, it is absolutely impossible without understanding how the project is currently operated.

After learning more about the Oracle Bone Integration and Digital Library projects, Mai Xiaomiao asked, "Elbow, let me ask you a question. Did you have the idea of ​​developing a neural network system from the beginning? Because from the current stage of these two projects, they are completely cell-element architecture systems, which fully conform to the bottom-level system structure of the neural network system. Next, we only need to study how to build an algorithm for the relationship between each element."

"Xiao Miao, you really think too highly of me." Zhou Zhi said with a smile, "The reason why these two projects are so special is that they are both literature and history research projects, which are completely different from the science and engineering projects that you are good at."

"I have been instilling a point of view in Tianyu Lidong Chunjia and others, that is, the logic system of science and engineering is often a system like a winding mountain road, with a clear path to the top of the mountain. This is the prominent feature of linear logic."

"The logical system of literature and history projects is actually a spherical network structure. In such a structure, can we succeed by using a system like a winding mountain road to solve problems?"

"It can indeed be successful on some minor and local issues. Let's take the same example again. For example, if you search for the word Su Shi, you can find all the passages in the historical books that mention Su Shi. At most, you can search for various tags under the term Su Shi, such as Dongpo, Huangzhou Tuanlian, The Red Cliffs, When Will the Moon Be There, etc., and get a biography of Su Shi and a historical evaluation of his life. This is already very difficult."

"It is of course remarkable to be able to achieve this, but there are often other types of questions that researchers of literature and history want to explore. Let me give you an example: "On the relationship between Su Shi's personality charm and the aesthetics of the Song people, and its influence on the aesthetics of later generations." For such questions, if you want to find answers in the current digital library, there are no ready-made answers. It requires a lot of learning and data collection, and then completing the correlation between the elements in the minds of scholars, and finally obtaining reliable conclusions through complex thinking."

"In theory, the information system can answer this question by itself." Mai Xiaomiao nodded: "As long as the two elements of cell samples and relational algorithms are rich enough, we can radiate from one point and traverse the entire net to obtain a large number of event probability combinations, and finally form a... in your words, a reliable conclusion."

"Don't ask me." Zhou Zhi said, "I should ask you, is this the goal of your laboratory?"

Mai Xiaomiao thought for a while and said, "I actually hadn't thought about it before, because my research was mostly theoretical. Before returning to China, I also learned about the current development situation in China. At that time, I thought the best deployment method was to use supercomputers to conduct some physical or astronomical research and try to perform nonlinear processing on the data. In other words, the computing power equipment is single, but the data is distributed."

"You are a liberal arts student with a richer imagination. You make my research romantic."

After saying that, he turned bitter again: "But the R&D costs may be..."
