Chapter 349: gmm/Gaussian hybrid model and pupil tracking

The second operating system prepared by Shi Lei is based on the GMM/Gaussian hybrid model, which is mainly used to develop voice systems.

The so-called high-mix model is a model that uses a Gaussian probability density function to accurately quantize a transaction and decompose a transaction into several Gaussian probability density functions, that is, a normal distribution curve.

The GMM model is commonly used as speech recognition and has gained wide application in the computer field. Although the speech recognition made by the GMM model has an error recognition rate of about 20-30, the error recognition rate is greatly reduced as long as the speech is sufficiently standard and the behavioral dynamic recognition engine monitors the lip language.

Lip behavior in lip language, through the behavioral dynamic recognition engine, can fully capture successful recognition. As for the voice command is sufficient standard, it is not that Shi Lei can control. After all, the local dialects are different and can only be based on Mandarin.

Shi Lei can definitely give a response. If you want to play "Brave World", you must have a standard Mandarin. Perhaps with the popularity of "The Brave World", in the territory of Xia Guo, there will be a craze for learning Mandarin!

If this is the case, "Brave World" may get the official recommendation of Xia Guo, if you can really get the official recommendation, then "The Brave World" will definitely fly!

The GMM Gaussian mixture model is not complicated. In natural language processing, this is only a shallow learning neural network. In 2006, a professor at the University of Toronto in Canada published an academic paper in the top scientific journal Science, which introduced the problem of deep learning neural networks. Many hidden layers of artificial neural networks have excellent feature learning ability, and the learned features have a more essential portrayal of data. This is the deep learning neural network corresponding to the shallow learning neural network.

Before Shi Lei was born again, in 2012, Stanford University and a large-scale computer system expert used 16,000 Core.CPUs together to build a model called Deep.Neural.Networks/Deep Neural Network, which was made in English. Simultaneous translation to Xia Guoyu, this translation process is very smooth, there is no half-pointing, and the error rate is not even one percent!

The pseudo artificial intelligence of the Angel Council is built using the DNN deep neural network model!

Unfortunately, Shi Lei has no time to develop a deep neural network model based on DNN. He can only make a shallow neural network based on GMM, make a speech recognition system, and then use the behavioral dynamic recognition engine to identify the lip language scheme and reduce the recognition error rate.

About the voice system, after development, not only can be cited in "Brave World", but also can be applied in many aspects.

Especially after combining the behavioral dynamic recognition engine, it is a very powerful system. With a voice recognition system, Shi Lei can control the computer with voice.

At that time, Shi Lei can even simulate the attack of two people by himself, or he can fight himself and make a better cover for his own identity.

There are also some monitoring systems that can do better. For example, medical monitoring systems, some patients who can not move can speak, then such patients can operate the medical system by voice, call nurses or doctors and other services.

Regarding the GMM-based speech system, in Shi Lei’s mind, there is another idea, that is

Returning to the theme of "Dragon World", it is possible to form a real somatosensory game with the behavioral dynamic recognition engine and the GMM voice system.

As for another difficulty, the problem of the character action system, Shi Lei intends to develop a third auxiliary operating system. That is to use the behavioral dynamic recognition engine to specifically track the player's pupil, and then use software calculations to determine the player's line of sight focus.

Regarding the pupil tracking technology, at present, no patent has been applied yet, and Shi Lei can just take this technology over. The original patent of this technology is Nokia, but unfortunately the decline of Nokia in the future, completely killed by Android.

The pupil tracking technology, applied in The Brave World, has many benefits. Combined with the behavioral dynamic recognition engine and the GMM voice system, it is possible to perfectly implement some difficult somatosensory operations.

For example, in light reality, in reality, the somatosensory operation that the player is absolutely impossible to achieve. As an example, if the player is on a cliff, he wants to use the light power to fly.

At this time, using somatosensory operation, it is impossible to find a place to jump down? Therefore, the pupil tracking technology can be applied, using the pupil tracking technology, and then a small jump action, you can jump from the cliff.

As for the rest of the cliff, the player's focus is determined, and then the characters in the game are controlled according to the pupil tracking technology.

To give another example, for example, in "Brave World", flying knife or bow and arrow attack, and other hidden weapon throwing, although players can easily make these moves, but can not just throw a direction?

If you throw a direction and dynamically identify the engine according to the behavior, although you can force the judgment of the target, but when faced with multiple targets? That will be powerless!

If you have a pupil tracking technique, calculate the visual focus by judging the pupil's line of sight to confirm which game target is locked, which one is for accurate attack.

Counting the pupil tracking technology, "Brave World" has introduced three sets of operation modes. These three sets of operation modes combine to form a perfect game control solution.

In 2007, on January 1, New Year's Day, at 5 o'clock in the afternoon, Shi Lei built the foundation for completing the GMM model. As for the pupil tracking technology and the lip language reading technology, it is possible to directly implement the technology by changing the strategy mode by the behavior dynamic recognition engine.

After standing up from the chair and stretching a lazy waist, Shi Lei walked out of the bedroom and prepared to find something to eat in the refrigerator.

Since the development of the GMM model, the production of the voice system, at lunch time, Shi Lei simply eat a little something to fill the hunger. As a foodie, Shi Lei’s hunger and starvation property is absolutely infinitely close to zero. He is hungry now, looking for something to eat.

Open the refrigerator and see, because there is no restocking for a long time, the refrigerator is empty, and even the milk is gone!

"The trough!" Shi Lei couldn't help but complain. "Nima, isn't this going to starve?"

Returning to the bedroom, grabbing the car keys on the computer desk, Shi Lei is ready to go out to eat, and by the way purchase some reserves. But when he just walked out the door, the phone in his trouser pocket rang.

The caller ID is Ouyang Xiang, and Shi Lei’s face is happy, and he quickly pressed the button.

"Hey, happy New Year, Ouyang!" Shi Lei first said in a step.

Ouyang Xiang’s voice is strong and strong, with a clear and clear, “Shi Lei, Happy New Year. Are you in Jingyayuan?”

"Well, I am!" Shi Lei responded. He suddenly remembered. Ouyang Xiang seems to be single alone in Jingyayuan. Ouyang Xiang’s father died early. She and her mother seem to have a bad relationship.

"Shi Lei, wait for a while to eat!" Ouyang Xiang's voice, with a concern, and a touch of joy.

Shi Lei was happy in his heart and secretly guessed why Ouyang Xiang suddenly told him to eat in the past. The relationship between the two of them, although Shi Lei took the initiative to let Ouyang Xiang, went to the anti-drug group to work, and eased down.

This kind of thing can be used for risotto, Shi Lei has always been cheeky, Ouyang Xiang has never taken the initiative.

Although I don't understand, why did Ouyang Xiang take the initiative to ask him to go to the rice, but how can Shi Lei have such a good thing?

"Ah, Ouyang, you are so good, I love you, I will come right away!" Shi Lei said quickly on the phone.

Ouyang Xiang snorted, "Less a poor mouth, come come!" After the end, Ouyang Xiang directly hang up the phone.

Shi Lei walked into the elevator with Xiaoqu and took the phone in his hand and rang again. Shi Lei thought it was Ouyang Xiang. When he was about to connect, he saw that it was Li Zhiyue!

This discovery scared Shi Lei a big jump. After he was just ready to connect, he and Ouyang Xiangkou spent a few words.

‘Nima ah Nima, the next time you turn on the phone, you must see the electric display! ‘It’s almost a big mistake, letting Shi Lei’s forehead take a cold sweat.

Taking a deep breath, Shi Lei connected the phone, and his tone was as flat as possible: "Know the moon, happy New Year!"

Li Zhiyue responded with a cry, "Shi Lei, Happy New Year."

Shi Lei knows that if there is nothing, Li Zhiyue can't take the initiative to call him. Especially in this world, Li Zhiyue has not been disfigured. Without psychological pressure, it is even more unlikely to take the initiative to call himself.

Since Li Zhiyue took the initiative to call, it means that Li Zhiyue should have something. "Know the moon, have you been okay recently?"

Li Zhiyue responded with some absent-mindedness: "It's okay."

Shi Lei heard that Li Zhiyue was not in a mood to chat. He knew Li Zhiyue very well, so he volunteered: "Knowing the moon, are you looking for me?"

"I" Li Zhiyue's tone is full of hesitation, "I"

Shi Lei is anxious. "What is the matter? Do you know what Wu Bin is, and come to harass you?" Wu Bin, Shi Lei’s mouth, is a calligraphy teacher at the Art Department of Shuangqing University, only 28 years old, at Shuangqing University. It can be said that young and promising, once went to Li Zhiyue's home, was originally deeply welcomed by Li Zhiyue's mother Huang Fen.

Li Zhiyue denied: "Not Wu Bin! He has not come to harass me now."

"What is that, ah, know what the month is, you will tell me! No matter what, I will help you!" Shi Lei asked anxiously.

In the past life, between Shi Lei and Li Zhiyue, there was a constant slap in the face, and the two platonic loves, even if the time interval is long, even if the life is heavy, Shi Lei will not forget!

This world, but because I saw Li Zhiyue again, seeing the perfect and innocent Li Zhiyue, Shi Lei loves her even more!

Li Zhiyue was silent and did not speak.

"Know the moon, if you don't say it, I will go to your home now!" Shi Lei couldn't help but ask a little more tough.
