349: gmm / Gaussian Mixture Model and Pupil Tracking

Sec­ond Op­er­at­ing Sys­tem of Shi Lei prepa­ra­tion, bases on the gmm / Gauss­ian Mix­ture Model com­put­ing mode, is mainly used to de­velop Vocal Sys­tem.

So-called high type Mix­ture Model, is one type with the Gauss­ian Prob­a­bil­ity Den­sity Func­tion pre­cise quan­tifi­ca­tion busi­ness, de­com­poses cer­tain Gauss­ian Prob­a­bil­ity Den­sity Func­tion a busi­ness, is the nor­mal curve of dis­tri­b­u­tion, but one model that forms.

gmm model usu­ally serves as the speech recog­ni­tion, in the com­puter do­main, ob­tained the wide­spread ap­pli­ca­tion. Al­though speech recog­ni­tion of gmm model man­u­fac­ture, will have about 20-30 error recog­ni­tion rates, so long as voice enough stan­dard, more­over co­or­di­nates the Dy­namic Be­hav­ior Recog­ni­tion En­gine mon­i­tor­ing lip lan­guage, this error recog­ni­tion rate meets re­duc­tion of sig­nif­i­cant.

Lip lan­guage as­pect lip Dy­namic Be­hav­ior, through Dy­namic Be­hav­ior Recog­ni­tion En­gine, can def­i­nitely the Seize suc­cess­ful recog­ni­tion. As for Voice Com­mand enough stan­dard, that is not, after all re­gional di­alects that Shi Lei can con­trol are dif­fer­ent, can only base on Man­darin is the stan­dard.

Shi Lei can af­firm gives the re­sponse, wants hobby «Brave's World», then must have stan­dard Man­darin. Per­haps along with being all the rage of «Brave's World», in Xia Na­tion, will also raise one to study the Man­darin up­surge!

If is re­ally this, «Brave's World» might ob­tain the rec­om­men­da­tion of Xia Na­tion Of­fi­cial, if can ob­tain the Of­fi­cial rec­om­men­da­tion, that «Brave's World» will meet fly in the sky like the leg­endary horse Fei Huang ab­solutely!

gmm Gauss­ian Mix­ture Model is not com­plex, in Nat­ural Lan­guage Pro­cess­ing, this is only shal­low layer study nerve net­work. In 6, the Toronto Uni­ver­sity pro­fes­sor, on Top Level sci­ences jour­nal " Sci­ence ", had is­sued a named dis­ser­ta­tion, in­tro­duced in-depth study nerve net­work issue. Ar­ti­fi­cial nerve net­work of many im­plicit strata have the Out­stand­ing char­ac­ter­is­tics learn­ing ca­pa­bil­ity, the char­ac­ter­is­tics that the study ob­tains have the por­tray of essence to data. This stud­ies the nerve net­work cor­re­spon­dence with the shal­low layer in-depth study nerve net­work.

Be­fore Shi Lei re­birth, 2012 time, by Stan luck Uni­ver­sity and large-scale Com­puter Sys­tem Spe­cial­ist, uses 16000 to­gether, the con­struc­tion named / Deep Neural Net­work Model, for­merly has made from the Eng­lish si­mul­ta­ne­ous in­ter­pre­ta­tion to the Xia Na­tion lan­guage, this trans­la­tion process is very smooth, sim­ply does not have half minute slow and un­re­spon­sive, error rate as­pect 1%!

Angel Par­lia­ment that Pseudo Ar­ti­fi­cial In­tel­li­gence, ex­actly as stated uses dnn Deep Neural Net­work Model to con­struct!
What a pity Shi Lei tem­porar­ily does not have the time, de­vel­ops dnn -based Deep Neural Net­work Model, can only make gmm -based Shal­low Neural Net­work, man­u­fac­tures Speech Recog­ni­tion Sys­tem, then using Dy­namic Be­hav­ior Recog­ni­tion En­gine, dis­tin­guishes the lip lan­guage the plan, re­duces the recog­ni­tion error rate.

About Vocal Sys­tem, after de­vel­op­ing, not only can quote in «Brave's World», but can also apply in many as­pect.
Es­pe­cially after Dy­namic Be­hav­ior Recog­ni­tion En­gine, that is very pow­er­ful Sys­tem. After hav­ing Speech Recog­ni­tion Sys­tem, Shi Lei then can voice con­trol com­puter.

When the time comes, Shi Lei even can a per­son sim­u­late two peo­ple's at­tacks , can fights, makes bet­ter con­ceal­ing for his iden­tity.
Some Mon­i­tor­ing Sys­tem, can achieve a bet­ter de­gree. For ex­am­ple the pa­tient who Treat­ment Mon­i­tor­ing Sys­tem, cer­tain can­not move can ac­tu­ally speak, then such pa­tient, can carry on op­er­a­tion med­ical ser­vice Sys­tem through the voice, sum­moned the nurse or Doc­tor wait / etc. served.

About gmm -based Vocal Sys­tem, in the Shi Lei heart, an idea, that is
The re­turn de­vel­ops the «Brave's World» sub­ject, is hav­ing Dy­namic Be­hav­ior Recog­ni­tion En­gine, as well as the gmm Vocal Sys­tem aux­il­iary co­or­di­na­tion, can form true Mo­tion Sens­ing Game.
As for an­other dif­fi­culty, Char­ac­ter Ac­tion Sys­tem issue, Shi Lei planned that de­vel­ops Third to as­sist Op­er­at­ing Sys­tem. Also uses Dy­namic Be­hav­ior Recog­ni­tion En­gine, traces the pupil of Gamer spe­cially, then using the soft­ware com­pu­ta­tion, de­ter­mines the Gamer line of sight focal point.

About Pupil Track­ing Tech­nol­ogy, this age has not ap­plied for the patent at pre­sent, Shi Lei hap­pen to can wrest away this tech­nol­ogy. This tech­ni­cal as­signor orig­i­nally is Nokia, was only a pity that later gen­er­a­tion Nokia de­clines, was killed by the An­droid sec­ond com­pre­hen­sively.

Pupil Track­ing Tech­nol­ogy, ap­plies in «Brave's World», the ad­van­tage has. In light of Dy­namic Be­hav­ior Recog­ni­tion En­gine and gmm Vocal Sys­tem, then can re­al­ize some dif­fi­cult Mo­tion Sens­ing Op­er­a­tion move­ments per­fectly.
For ex­am­ple weight­less method, in Re­al­ity, Gamer is ab­solutely im­pos­si­ble Mo­tion Sens­ing Op­er­a­tion that re­al­izes. Cites an ex­am­ple to ex­plain, if Gamer on a sheer precipice, wants to use the weight­less method div­ing pos­ture to get down.

At this time, used Mo­tion Sens­ing Op­er­a­tion, was al­ways im­pos­si­ble to find a place to jump Right? there­fore, Pupil Track­ing Tech­nol­ogy can apply, used Pupil Track­ing Tech­nol­ogy, then the jump of small scope, can jump from the cliff.
As for var­i­ous place footholds of cliff, then needs the focal point line of sight of Gamer to de­ter­mine that then ac­cord­ing to Pupil Track­ing Tech­nol­ogy, will play the char­ac­ter to cor­re­spond the con­trol in the past.

Cites an ex­am­ple to ex­plain again that for ex­am­ple in «Brave's World», the throw­ing knife throws or is bow and arrow at­tack, as well as other con­cealed or hid­den weapons throw, al­though Gamer can make these move­ments with ease, but can­not tum­ble di­rec­tion Right? ca­su­ally
If throws down a di­rec­tion, ac­cord­ing to Dy­namic Be­hav­ior Recog­ni­tion En­gine, al­though can force de­ter­mine to lock tar­get, but faces many tar­get time? That will be help­less!

If had Pupil Track­ing Tech­nol­ogy, through de­ter­mine pupil line of sight com­pu­ta­tion vi­sual focus, thus game tar­get of con­firmed lock­ing, is ac­tu­ally, to be ad­van­ta­geous ac­cu­rate at­tack.
Was counted Pupil Track­ing Tech­nol­ogy, «Brave's World» in­tro­duced three op­er­at­ing mode, these three op­er­at­ing modes linked, will form a per­fect game scheme.

In 2007, on Jan­u­ary 1, the New Years fes­ti­val, around 5 : 00 pm, Shi Lei built the ac­com­plish gmm model foun­da­tion. As for Pupil Track­ing Tech­nol­ogy and Lip-Speech Read­ing Tech­nol­ogy, can def­i­nitely by Dy­namic Be­hav­ior Recog­ni­tion En­gine, change the strat­egy way, re­al­izes this tech­nol­ogy di­rectly.
Stands from the chair, after ex­tend­ing stretched, Shi Lei goes out of the bed­room, pre­pares in the re­frig­er­a­tor, looks east and west|thing that some can eat.

Be­cause de­vel­ops gmm model, man­u­fac­tures Vocal Sys­tem, the lunch time, Shi Lei was only eats east and west|thing to ap­pease hunger sim­ply. As Foodie, Shi Lei's en­dures the hunger to bear the hun­gry at­tribute ab­solutely is in­fi­nite close zero, he now was hun­gry, must look for east and west|thing to eat.
Opens the re­frig­er­a­tor to look, be­cause long time has not sup­ple­mented the goods in stock, the re­frig­er­a­tor is com­pletely empty, un­ex­pect­edly did not have in­clud­ing the milk!

„Damn!” Shi Lei could not bear com­plain, „Your Mother, this didn't want the starv­ing to death elder brother?”
Re­turns to the bed­room, works on car key on com­puter table, the Shi Lei prepa­ra­tion goes out to dine, pur­chases a re­serve while con­ve­nient. But when he just went out of the gate, tele­phone in the trouser pocket, has then rung.

Caller ID is Ouyang Xiang, the Shi Lei com­plex­ion one happy, has pressed down the con­nec­tion key hastily.
„Hey, New Years is joy­ful, Ouyang!” Shi Lei one step opens the mouth to say first.
The Ouyang Xiang sound was firm and res­olute, hav­ing a clear(ly) to be pleased, „Shi Lei, New Years was joy­ful. You in Jingya Gar­den?”

„En, I in!” The Shi Lei re­sponse said that he sud­denly thinks, Ouyang Xiang is also un­mar­ried one per­son in Jingya Gar­den, the Ouyang Xiang fa­ther early per­ishes prob­a­bly, she and her mother, the re­la­tions are very not as if good.
„Shi Lei, waits a while to eat meal!” In the Ouyang Xiang sound, is hav­ing a care, as well as a light joy.

In the Shi Lei heart likes, guessed why se­cretly Ouyang Xiang asked him to eat meal sud­denly in the past. Their re­la­tions, be­cause al­though Shi Lei lets Ouyang Xiang on own ini­tia­tive, goes to the Drug En­force­ment Group work, but re­laxes.
May dine this mat­ter, is al­ways Shi Lei in­sen­si­tively vis­its, Ouyang Xiang has not raised on own ini­tia­tive.

Al­though does not think clearly, why Ouyang Xiang asked him to dine on own ini­tia­tive, but there are to dine this good mat­ter, did Shi Lei pos­si­bly let off?
„, Ouyang, you were re­ally good, I loved you, I im­me­di­ately came!” Shi Lei said in the tele­phone hastily.

Ouyang Xiang light snort, „lit­tle lo­qua­cious, must come to come!” After say­ing, Ouyang Xiang has hung up the tele­phone di­rectly.
The Shi Lei hum lit­tle song en­ter­ing el­e­va­tor, in the tele­phone in hand, has made a sound once more. Shi Lei also thinks is Ouyang Xiang, is prepar­ing to put through time, the glar­ing sees un­ex­pect­edly is Li Zhiyue!

This dis­cov­ery, in a big way fright­ened Shi Lei one to jump, after he just also pre­pared to put through, with Ouyang Xiang mouth col­ored two.
‚Your Mother Your Mother, will con­nect the call be­fore next time, must look at Caller ID!’ Nearly leads to the blun­der, mak­ing the Shi Lei fore­head break into sweat.

Deeply in­spired, the Shi Lei con­nec­tion tele­phone, the ex­pres­sion said as far as pos­si­ble lightly: „Zhiyue, New Years is joy­ful!”
Li Zhiyue re­sponded to one, „Shi Lei, New Years is joy­ful.”

Shi Lei knows, if no mat­ter, Li Zhiyue is im­pos­si­ble to call him on own ini­tia­tive, es­pe­cially this, Li Zhiyue had not been dis­fig­ured one's face, does not have in the sit­u­a­tion of pres­sure, not too pos­si­bly on own ini­tia­tive tele­phones to one­self.
Since Li Zhiyue tele­phones on own ini­tia­tive, that ex­plained that what mat­ter Li Zhiyue should have, „Zhiyue, you re­cently for­tu­nately?”

Li Zhiyue has some ab­sent-minded re­sponses: „For­tu­nately.”
Shi Lei can hear, Li Zhiyue does not have the mood to chat, he un­der­stands Li Zhiyue, there­fore asked on own ini­tia­tive: „Zhiyue, what mat­ter do you ask me to have?”

„I” the Li Zhiyue ex­pres­sion have been full of the hes­i­tant fla­vor, „I”
Shi Lei some­what wor­ries, „is Zhiyue, ac­tu­ally what mat­ter? Is what Wu Bin that also ha­rassed you?” Wu Bin in Shi Lei mouth, is the Shuangqing Uni­ver­sity Art De­part­ment Cal­lig­ra­phy teacher, 28 years old, are young and promis­ing in Shuangqing Uni­ver­sity, for­merly went to in the Li Zhiyue home, orig­i­nally deeply by lik­ing of Li Zhiyue mother Huang Fen.
Li Zhiyue de­nied: „It is not Wu Bin! He has not ha­rassed me now.”

„That is any mat­ter, Zhiyue, has any mat­ter, you told me! Any mat­ter, I will help your!” Shi Lei anx­ious was ask­ing.
pre­vi­ous life, be­tween Shi Lei and Li Zhiyue, fet­ters of shear, their pla­tonic love, even if the time-gap is long, even if the heavy labor first, Shi Lei will not have for­got­ten as be­fore!

This, be­cause in­stead sees Li Zhiyue once more, sees per­fect Li Zhiyue, Shi Lei loves her!
Li Zhiyue is silent, has not spo­ken.
„Zhiyue, if you did not say that I go to your home now!” Shi Lei can­not bear is slightly strong a point the in­quiry.
