So, forexample, let's let's consider a translationchapup a translationtasklikeEnglishtoFrench.
Ingeneral, ifyouwanttotranslateEnglishorFrenchorEnglishorGermanorEnglishorSpanish, there's theremightbeslightvarianceinthesyntaxoflike, a nounphrase.
Butingeneralthere's a algorithmicsolvingofthetranslationofEnglishthio, French, German, Spanish, whatever.
That's pretty, Prettysimple, I guess.
Anditgoesin a linearorder.
Butthenyouhave a languagelikeJapanese, soEnglishandJapanesearevery, verydifferentlanguages, andtheydon't followevenremotelysimilarrulesandinJapanese, Sometimesthatlastcharacterchangesthemeaningofalltheothercharacters.
Andthingswerejusttotallydifferent, right?
Andthenalsowiththechatbought, thesamethingistrue.
Andin a lotoftranslations, samethingistruethatit's likewithan L S t m generallyand l s t m isreallyprettygoodatrememberingin a sequenceabout, like, 10 tomaybe 20 tokens.
There's a slightdeclinethere, butitprettymuchholdsoutallthewayupto 70 andprobablyoutfurtherfromthere.
So, um, sotheattentionmodel's gonnahelpusrememberlongersequencesat a timewhichcanhelpustokindofbruteforceourwaythroughthiskindofcontextproblemwhereweneedbothhistoricalandfutureinformation.
Sofrommodel, what I'm gonnadois I'm gonnaopenup a commandpromptjustwithCMDtypinginthereandthenjusttypetensorboarddashdashloggerequalstrainedunderscorelaw.
Andthenyouwouldhitinher.
Now, actually, I haven't cancelexactuallyalreadyhaveitup.
I wantedtobringituppriorbecause, uh, itcantake a littlebittoload, and I'm loadinglike 100,000 steps.
Butwhenyou'retranslatingEnglishtoEnglish, whenyou'redoinglike a chapby, likeitinputtoanoutputcommentin a responsefromanygivencomment, it's reallylikeinfiniteresponses.
I stoppedthemodelbecauseone I'vehadalreadydecreasedlearningrateasmuchas I feltitwasnecessaryanditlookedliketrainlosswasmaybeevenstartingtoclimbagain.
Sothere's reallynoreasontokeeptrainingthismodel, inmyopiniononandthen, forwhateverreason, whenwedo a bidirectionalcurrentneuralnetwork, thisgraphjustdoesn't work.
So I thinkthat's a bugintheinthecodebecauseitdoesworktotallyfine.
Uh, with a nonbidirectionalcurrentornetwork.
Anyway, that's yourtensorboardstuff.
I dowanttobringupum, I guess I'llbringdowntheotherone.
So I haveyouhave a modelthat's trainingrightnowonpaperspace?
Uh, isthatokay?
I thinkyoucouldseethat.
Yes.
Asyoucansee, thisisTensorBird.
I gotcensorboardrunningrighthere.
I'm currentlyonstep 59,000.
Thingswerelookingprettygood.
I haven't decayedanythingjustyet.
Uh, trainlosskeepsgoingdown.
Theotherthing I wanttobringuptoissoSothere's 22 twomajormetrics, right?
Blue, whichwe'vealreadydiscussed.
It's basicallyhowgoodof a translationisit?
Um, AndthenPPLisperplexityandperplexitiesisthis?
It's basicallyjust a probabilitydistribution.
Soit's howfaroffareyou?
Sobluescore.
It's likethemorethebetterwherehisperplexityis.
We'd likethattobe a smallestpossible.
We'd likeperplexitytobein, like, thesingledigits, ifpossibleagainonEnglishon a chat.
Bott.
That's prime.
NotgonnahappenonEnglishtoFrench.
Weactuallycouldget a perplexityinthesingledigits, butyeah, probablythechap.
We'renotgonnabeabletodothat.
Andifwedid, we'd probablyjustoverfit.
That's myguess.
Soanyway, themainnumbersWe'relookingforhisperplexityingeneral, if I recall, right, theperplexingandCharles V totheonethat's liveonTwitter, atleastatthetime I recordingthis, althoughhe's probablygonnabereplacedwiththismodelwhenit's done.
Um, I thinkyou'vegottentolikethefifties.
I don't thinkheevengotteninthefortiesforperplexity.
Butthesewerejustgeneralnumbersagain.
ThehardpartwithEnglishEnglishwith a chappotisthere's noset.
I forgethowmanyparksthatwouldbewas 100,000 times 1 28 which, unlessmymathiswrong, thenbelike 12.
Me, likefour.
Youbox?
I don't know.
Hopefully I'm notoffbyanorderofmagnitude, but I thinkit's aboutfourblocks.
Wordsherewonheeparkwouldbelike 480,000 steps, sothatis a lotofsteps.
Whereasthisoneonlyhadtodo 100,000 stepstodo a fewpox.
Thisone's gonnahavetodo 480,000 justforonenight.
Andmyhopeisthatbecauseallthatdataisuniquelikeeverysingleinputdata, everysinglesampleis a uniquesample.
Myhopeisthatit's goingtobemuchmoreaccuratein a muchmoreinterestingandunique.
Andhisresponseswon't necessarilypieceofsimilarsooftenbecauseeverysingleonehe's seenevenupto 500,000 stepswillbe a newunique, neverbeforeseensampleandideally, at I'd hopedtobeabletodotohypoxia, thatwouldbelike a 1,000,000 steps.
Andthat's gonnatakeeventhisone's gonnatake.
I forget, I thinkeightdaystogettomaybe a littlelessthaneightdaysabout a weekjusttodooneiPAQ.
So, yeah, I'm notsure I wanttodotwoweeksoftraining, Okay, buthonestlyup.
I'lljustkeeptraininguntiltraininglossuntil I gettoonenegativeforAndtraininglossstillwon't decline.
Untilthen, I'm gonnakeeptrainingandhopingthatunlessunlessperplexitystartsgoingupcrazilyorbluescorestartsfallingorsomethinglikethat, but, um, yeah, Okay, so a lotofinformation I probablymissedsomestuff.
