INTRODUCTION ONE of the ma drawbacks of eural etworks s ts lack of hgh-level represetg power of the kowledge leart ad represeted ther weghts. Oe way to overcome ths problem s to mplemet the represetg power of atural laguages to the structures of eural etworks. The physcal lgustcs s the very framework to make atural laguage measurable ad therefore, the best tool to mplemet the represetg power of atural laguages to the structures of eural etworks. The author wll preset a eural etwork structure where computatoal verbs wll be workhorses to brg the hgh-level kowledge represetg power to the doma of measuremets. I [38], the author preseted the learg algorthms for sets of computatoal verb rules. These learg algorthms ca be readly trasformed to ft to the cofguratos of computatoal verb eural etworks. A computatoal verb eural etwork s the result of verbfyg a covetoal eural etwork. There are may ways to verbfy the attrbutes of a covetoal eural etwork. For example, oe ca verbfy the puts, outputs, weghts, ad bases of a covetoal eural etwork. The author wll study the followg two types of computatoal verb eural etworks. 1 Type-I computatoal verb eural etwork cossts of verbfed puts ad real outputs. All other attrbutes of are umercal. 2 Type-II computatoal verb eural etwork cossts of verbfed puts ad outputs. All other attrbutes of are umercal.

A BRIEF HISTORY OF COMPUTATIONAL VERB THEORY As the frst paradgm shft for solvg egeerg problems by usg verbs, the computatoal verb theory ad physcal lgustcs have udergoe a rapd growth sce the brth of computatoal verb the Departmet of Electrcal Egeerg ad Computer Sceces, Uversty of Calfora at Berkeley 1997[8], [9]. The paradgm of mplemetg verbs maches were coed as computatoal verb theory[22]. The buldg blocks of computatoal theory are computatoal verbs[17], [12], [1], [18], [23]. The relato betwee verbs ad adverbs was mathematcally defed [11]. The logc operatos betwee verb statemets were studed [13]. The applcatos of verb logc to verb reasog were addressed [14] ad further studed [22]. A logc paradox was solved based o verb logc[19]. The mathematcal cocept of set was geeralzed to verb set [16]. Smlarly, for measurable attrbutes, the umber systems ca be geeralzed to verb umbers[2]. The applcatos of computatoal verbs to predctos were studed [15]. I [24] fuzzy dyamc systems were used to model a specal kd of computatoal verb that evolves a fuzzy space. The relato betwee computatoal verb theory ad tradtoal lgustcs was studed [22], [25]. The theoretcal bass of developg computatoal cogto from a ufed theory of fuzzy ad computatoal verb theores s the theory of the Ucogse that was studed [25], [3]. The ssues of smulatg cogto usg computatoal verbs were studed [26]. A way to mplemetg feelgs maches was proposed based o grouded computatoal verbs ad computatoal ous [32]. I [39] a ew defto of the smlarty betwee computatoal verbs was studed. The theory of computatoal verb has bee taught some uversty classrooms sce The latest actve applcatos of computatoal verb theory are lsted as follows. 1 Computatoal Verb Cotrollers.

For the advaced applcatos of computatoal verbs to cotrol problems, two papers reportg the latest advaces had bee publshed[28], [27]. The desg of computatoal verb cotroller was also preseted a textbook 26[1]. 2 Computatoal Verb Image Processg ad Image Uderstadg. The recet results of mage processg by usg computatoal verbs ca be foud [29]. The applcatos of computatoal verbs to mage uderstadg ca be foud [31]. 3 Stock Market Modelg ad Predcto based o computatoal verbs. The product of Cogtve Stock Charts[4] was based o the advaced modelg ad computg reported [33]. Applcatos of computatoal verbs was used to study the treds of stock markets kow as Russell recostructo patters [34]. Computatoal verb theory has bee successfully appled to may dustral ad commercal products. Some of these products are lsted as follows. 1 Vsual Card Couters. The YagSky-MAGIC card couter[6], developed by Yag s Scetfc Research Isttute ad Wux Xgcard Techology Co. Ltd., was the frst vsual card couter to use computatoal verb mage processg techology to acheve hgh accuracy of card ad paper board coutg based o cheap webcams. 2 CCTV Automatc Drver Qualfy Test System. The DrveQfy CCTV automatc drver qualfy test system[7] was the frst vehcle traectory recostructo ad stop tme measurg system usg computatoal verb mage processg techology. 3 Vsual Flame Detectg System. The FreEye vsual flame detectg system[2] was the frst CCTV or webcam based flame detectg system, that works uder color ad black & whte codtos, for survellace ad securty motorg system[36], [37]. 4 Smart Porographc Image ad Vdeo Detecto Systems. The PorSeer[5] porographc mage ad vdeo detecto systems are the frst cogtve feature based smart poro detecto ad removal software. 5 Webcam Barcode Scaer. The BarSeer[3] webcam barcode scaer took advatage of the computatoal verb mage processg to make the sca of barcode by usg cheap webcam possble. 6 Cogtve Stock Charts. By applyg computatoal verbs to the modelg of treds ad cogtve behavors of stock tradg actvtes, cogtve stock charts ca provde the traders wth the feelgs of stock markets by usg smple ad tutve dexes. III. TYPE-I COMPUTATIONAL VERB NEURAL NETWORKS A type-i computatoal verb eural etworkvnn 2 takes mplemetatos of computatoal verbs as puts, compares the put verbs wth some template verbs ad output real umbers. Therefore, a type-i VNN has verbs as puts ad 2 Istead of usg CVNN, we use VNN to stad for computatoal verb eural etwork to avod clutter. real umbers as outputs. I a type-i computatoal verb eural etwork, for put waveforms x t R, t [, T ], = 1,...,, there are template computatoal verbs V such that the computatoal verb smlarty betwee x t ad the evolvg fucto of V, E t, wll be weghted ad results the output y R of the euro as follow. y = f w Sx t, E t θ, t [, T ] 1 where S, s a computatoal verb smlarty[35], θ R s the bas of the euro ad the fucto f s the trasfer fucto for the euro. Gve m caocal computatoal verbs, {Ẽ} m, we ca represet a computatoal verb as E t = m α Ẽ t 2 where α R are costats ad ca be vewed as adverbs. Assume that we have K set of trag examples {u k1 t,..., u k t, d k } K, where u kt, = 1,...,, are put waveforms ad d k s the correspodg output. Our goal s to lear all computatoal verbs E t ad bas θ from the trag examples. For the kth trag sample, we costruct a output y k as, y k = f w Su k t, E t θ, 3 based o whch we costruct the followg error fucto. E = y k d k 2. 4 The learg rules are gve by w l + 1 = w l + γ w l w l, θl + 1 = θl + γ θ l θl, α l + 1 = α l + γ α l α l, l =,..., where γ w l R+, γ θ l R + ad γ α l R+, = 1,..., ; = 1,..., m, are learg rates for trag terato l, ad w E w y k d k 2 5 w 2 y k d k y k w 2 y k d k f w h Su kh t, E h t θ Su k t, E t, 6

TYPE-II COMPUTATIONAL VERB NEURAL NETWORKS A type-ii VNN has verbs as puts ad verbs as outputs. A euro a type-ii computatoal verb eural etwork s represeted as E y t = w Sx t, E te t E θ t, t [, T ] 11 where E y t s the evolvg fucto of the output computatoal verb, E θ t R s the verb bas of the euro. Gve m caocal computatoal verbs, {Ẽ} m, computatoal verbs E t, = 1,...,, are costructed as Eq. 2 ad E θ t s costructed as m E θ t = α θ Ẽt 12 where α θ R are costats ad ca be vewed as adverbs. Assume that we have K set of trag examples {u k1 t,..., u k t, d k t} K, where u kt, = 1,...,, are put waveforms ad d k t s the correspodg output verb. Our goal s to lear all computatoal verbs E t ad bas verb E θ t from the trag examples. For the kth trag sample, we costruct a output y k t as, y k t = w Su k t, E te t E θ t, 13 based o whch we costruct the followg error fucto. E = The learg rules are gve by w l + 1 = w l + γ w l w l, α θ l + 1 = α θ l + γ θ l α θ l, [y k t d k t] 2 dt. 14 α l + 1 = α l + γ α l α l, l =,..., 15 where γ w l R+, γ θ l R+ ad γ α l R+, = 1,..., ; = 1,..., m, are learg rates for trag terato l, ad w E w 2 2 α θ E α θ 2 = 2 [y k t d k t] 2 dt w [y k t d k t] y kt dt w [y k t d k t]su k t, E te t, α E 2 [y k t d k t] 2 dt α θ [y k t d k t] y kt α θ dt 16 [y k t d k t]ẽt, 17 [y k t d k t] 2 dt [y k t d k t] y kt dt 18

V. SINGLE-LAYER FEEDFORWARD TYPE-I VNN The structure of sgle-layer feedforward type-i VNN s show Fg. 1. We assume that there are put odes, m hdde odes ad 1 output ode. The weght w, = 1,..., ; = 1,..., m, coects betwee the th put ode ad the th hdde ode. The weght v coect the th hdde ode to the oly output ode. x 1 t x 2 t x t Fg. 1. Iput layer w f, θ f, θ f, θ Hdde layer v g, θ Output layer The structure of sgle-layer feedforward type-i VNN. The put-output relato of ths VNN s gve by m y = g v f w Sx t, E t θ θ 2 where each computatoal verb s costructed based o p caocal computatoal verbs p E t = α h Ẽ h t. 21 y Remark. If Eq. 2 we choose a computatoal verb smlarty ad a set of computatoal verbs such that Sx t, E t = x t ad oly cosder oe sample pot of the put waveforms, the VCNN 2 degeerates to the followg covetoal feedforward eural etwork wth oe hdde layer. m y = g v f w x θ θ. 22 The geeral cocluso s that all covetoal eural etworks ca be verbfed to computatoal verb eural etworks. Theorem 1. Assume that {u k t, d k }, k = 1,..., K, are K trag samples that are depedet ad have the same dstrbuto. u k t C[, T ] C[, T ]..., C[, T ] ad }{{} d k R. g s mootoc creasg. The for ay a gve approxmato error ε R +, the VNN 2 ca approxmate the put-output relato defed by the trag set f the umber of hdde odes, m, s bg eough. Proof. The kth trag sample s u k t, d k = u k 1,..., uk, d k. 23 It follows from Eq. 2 that the kth trag sample satsfes Eq. 24. The for the trag samples {u k t, d k }, k = 1,..., K ad a gve error ε Eq. 25 s satsfed. I Eq. 25 w, v, α h ad θ are adustable parameters to be determed. Therefore, Eq. 25 defes a rego the parameter space to clude the soluto to the put-output relato defed by the trag samples. The exstece of such a soluto s guarateed by prcples of olear programmg for each fxed θ whe we choose the total umber of parameters o less tha the umber of trag samples; amely, m+m+p K. Remark. It follows from the cocluso [38] that the set of olear equatos ca be solved umercally. The detals ca be foud from Sec. IV of [38]. Theorem 2. For VNN 2, assume that {x k t, y k }, k = 1, 2, are 2 put-output pars where x k t C[, T ] C[, T ]..., C[, T ] ad y k R, ad assume }{{} that f ad g are cotuous, the for ay ε >, there

CONCLUDING REMARKS The results preseted ths paper revealed the brad ew opeg to a ew world of learg from dyamcal data or tme seres. The potetals of applyg VNN to facal world are tremedous f we vew the records of tra-day stock prces as dfferet computatoal verbs ad trasform the data-mg problem of tra-day stock prces to a learg problem of VNN. Needless to say, may smlar cases exst applcatos where dyamcal observatos are of regular tme wdows ad the kowledge dscovery from these data becomes mpossble f we oly vew each observatos solated, wthout cosderg the embedded atural tme-le them. It s the author s vso that wth te years, computatoal eural etwork aloe wll become a comprehesve dscple the famly of computatoal verb theory. REFERENCES [1] Guarog Che ad Trug Tat Pham.
