The second cao system prepared by Shi Lei is based on the calculation method of GMM Gaussian hybrid model, which is mainly used to develop voice systems.
The so-called high-form hybrid model is a model formed by using the Gaussian probability density function to accurately jing the quantitative transaction, decomposing a transaction into several Gaussian probability density functions, that is, normal distribution curves. . .
The gmm model is usually used as speech recognition and has been widely used in the computer field. Although the speech recognition produced by the gmm model will have an error recognition rate of about 2030%, as long as the speech is sufficiently standard and the lip-syncing engine is used to monitor the lip, the error recognition rate will be greatly reduced.
The lip behavior dynamics in lip language can be captured successfully through the behavior dynamic recognition engine. As for the sufficient standard voice commands, it is not something Shi Lei can control. After all, different dialects are different, and they can only be based on Mandarin.
Shi Lei can respond with certainty. If you want to play "World of the Braves", you must have a standard Mandarin. Perhaps with the popularity of "World of the Braves", a craze for learning Mandarin will be set off in Xia Kingdom!
If this is true, "World of the Braves" may be officially recommended by Xia Guo. If it can be officially recommended, "World of the Braves" will definitely make a fortune! . .
GMM Gaussian hybrid model is not complicated. In natural language processing, this is just a shallow learning neural network. In 2006, a professor at the University of Toronto, Canada published an academic paper in the top scientific journal "Science". It introduced the problem of deep learning neural networks. Many hidden artificial neural networks have excellent feature learning ability, and the learned features have a more essential characterization of data. This is the deep learning neural network corresponding to shallow learning neural networks.
The deep neural network model built by pu is called deep.neural.works. It has been translated from English to Xia Mandarin. The translation process is very smooth, without any lag at all, and the error rate is less than one percent!
The pseudo-artificial intelligence of Angel Council is built using the DNN deep neural network model!
Unfortunately, Shi Lei has no time yet to develop a deep neural network model based on DNN. He can only make a shallow neural network based on GMM, create a speech recognition system, and then use a dynamic behavior recognition engine to identify lip words to reduce the recognition error rate.
About the voice system. After it is developed, it can not only be cited in "World of the Brave", but also applied in many aspects.
Especially after combining with the behavior dynamic recognition engine, it is a very powerful system. With the voice recognition system, Shi Lei can voice control the computer.
At that time, Shi Lei can even simulate the attack of two people alone, or fight with himself, making better cover-ups for his own identity.
There are also some monitoring systems that can also be achieved to a better extent. For example, medical monitoring systems, some patients who cannot move can speak, so such patients can use voice to perform medical systems, calling for nurses or doctors and other services.
Regarding the GMM-based voice system, Shi Lei has another idea, that is
Returning to the theme of "World of the Brave", only by having a dynamic behavior recognition engine and aiding and cooperating with the GMM voice system can a real somatosensory game.
As for another difficulty, the problem of character action system, Shi Lei plans to develop a third auxiliary cao system. That is, using a behavior dynamic recognition engine to specifically track the player's pupils, and then use software calculations to determine the player's focal point.
Regarding pupil tracking technology, there has not been a patent application in this era, and Shi Lei can occupy this technology. The original patentee of this technology was Nokia, but unfortunately, Nokia declined in later generations and was sold out by Android in an all-round way.
The pupil tracking technology is used in "World of the Brave" and has many benefits. Combined with the behavior dynamic recognition engine and the GMM voice system, it can perfectly realize some difficult somatosensory actions.
For example, light skills, in reality, players will never be able to achieve somatosensory work. To give an example, if a player wants to use light skills to fly down on a cliff.
At this time, using somatosensory cao, it is impossible to find a place to jump down? So, the pupil tracking technology can be applied, and the pupil tracking technology can be used, and then a small jumping action can jump off the cliff.
As for the footholds of the cliff, the player's focus and gaze are required to determine, and then according to the pupil tracking technology, the characters in the game are controlled by correspondingly.
Let me give you another example. For example, in "World of the Brave", when throwing a flying knife or attacking a bow or arrow, and throwing other hidden weapons, players can easily make these actions, but they can't throw them in a random direction?
If you throw a direction litter and dynamically identify the engine according to the behavior, although it can forcefully determine the locking target, what if you face multiple targets? Then you will be powerless!
If you have pupil tracking technology, you can calculate the visual focus by judging the pupil's line of sight, and then confirm which game target is locked to facilitate accurate attacks.
Including pupil tracking technology, "World of the Brave" has introduced three sets of cao-making methods. Combining these three sets of cao-making methods will form a perfect game control solution.
On January 1, 2007, New Year's Day, at around 5 p.m., Shi Lei built the foundation for the GMM model. As for pupil tracking technology and lip reading technology, it can be completely changed by the behavior dynamic recognition engine to directly implement this technology.
After standing up from the chair and stretching, Shi Lei walked out of the bedroom and prepared to find something to eat in the refrigerator.
Because of developing the GMM model and making a voice system, during lunch, Shi Lei simply ate a little something to satisfy his hunger. As a foodie, Shi Lei's hunger and hunger class is definitely infinitely close to zero. He is hungry now and wants to find something to eat.
When I opened the refrigerator, I saw that since I had not replenished the inventory for a long time, the refrigerator was empty. It was even empty!
"Damn!" Shi Lei couldn't help but complain, "Damn, isn't this going to starve to death?"
Returning to the bedroom, grabbing the car keys on the computer desk, Shi Lei was about to go out for dinner and purchase some reserves. But when he just walked out of the door, the phone in his pants pocket rang.
The caller ID was Ouyang Xiang. Shi Lei was happy and quickly pressed the switch button.
"Hey, happy New Year's Day, Ouyang!" Shi Lei spoke first.
Ouyang Xiang's voice was firm and powerful, with a sense of brightness and tranquility, "Happy New Year's Day. Are you in Jingyayuan?"
"Yeah, I'm here!" Shi Lei responded. He suddenly remembered that Ouyang Xiang seemed to be single in Jingyayuan. Ouyang Xiang's father died prematurely, and her relationship with her mother seemed to be very bad.
"Shi Lei, come here to have a meal later!" Ouyang Xiang's voice was filled with concern and a faint joy.
Shi Lei was happy and secretly guessed why Ouyang Xiang suddenly called him over for dinner. The relationship between them was eased because Shi Lei took the initiative to ask Ouyang Xiang to work in the drug control team.
But Shi Lei has always been a shameless person to come to the house for free, and Ouyang Xiang has never mentioned it on his own initiative.
Although I can’t understand why Ouyang Xiang took the initiative to ask him to have a free meal, how could Shi Lei let go of such a good thing as a free meal?
"Ah, Ouyang, you are so good. I love you so much, I'll come over right away!" Shi Lei said quickly on the phone.
Ouyang Xiang snorted lightly, "Stop talking, come if you want to come!" After that, Ouyang Xiang hung up the phone directly.
Shi Lei walked into the elevator humming a small song, and the phone in his hand rang again. Shi Lei thought it was Ouyang Xiang, and when he was about to connect, he saw that it was Li Zhiyue!
This discovery scared Shi Lei. He was just about to connect and talk to Ouyang Xiangkou.
‘Damn it, yes, before answering the phone next time, you must look at the caller ID!’ It almost caused a big mistake, which made Shi Lei sweat on his forehead.
Taking a deep breath, Shi Lei answered the phone and said in a calm tone: "Zhiyue, happy New Year's Day!"
Li Zhiyue responded, "Shi Lei, happy New Year's Day."
Shi Lei knew that if there was nothing, Li Zhiyue would not be able to call him on his own initiative, especially in this life, when Li Zhiyue was not disfigured and without psychological pressure, it was even less likely to call him on his own initiative.
Since Li Zhiyue took the initiative to call, it means that Li Zhiyue should have something to do, "Zhiyue, how are you doing recently?"
Li Zhiyue responded absent-mindedly: "It's okay."
Shi Lei could hear that Li Zhiyue was not in the mood to chat. He knew Li Zhiyue very well, so he took the initiative to ask: "Zhiyue, is there anything you have to do with me?"
"I" Li Zhiyue's tone was full of hesitation, "I"
Shi Lei was a little anxious, "Zhiyue, what's going on? Is that Wu Bin coming to disturb you again?" The Wu Bin mentioned in Shi Lei is a calligraphy teacher in the Department of Art of Shuangqing University. He is only 28 years old and is young and promising at Shuangqing University. He once went to Li Zhiyue's home and was originally deeply happy with Li Zhiyue's mother Huang Fen.
Li Zhiyue denied: "It's not Wu Bin! He hasn't come to bother me now."
"What's that matter? Zhiyue, tell me what's the matter! No matter what matters, I will help you!" Shi Lei asked anxiously.
In the previous life, there was an endless bond between Shi Lei and Li Zhiyue. The two of them had a Platonic relationship. No matter how long the time was, even if they lived for a lifetime, Shi Lei would still not forget it!
In this life, because I saw Li Zhiyue again and the flawless Li Zhiyue, Shi Lei loved her even more!
Li Zhiyue was silent and didn't say anything.
"Zhiyue, if you don't say it, I'll go to your home now!" Shi Lei couldn't help asking a little tougher.
