Pneumoni. ranks as a leadi.g cause of mortali.y, parti.ularly i. chi.dren aged fi.e and under. Detecti.g thi. di.ease typi.ally requi.es radi.logi.ts to exami.e chest X-rays and report thei. fi.di.gs to physi.i.ns, a task suscepti.le to human error. The appli.ati.n of Deep Transfer Learni.g (DTL) for the i.enti.i.ati.n of pneumoni. through chest X-rays i. hi.dered by a shortage of avai.able i.ages, whi.h has led to less than opti.al DTL performance and i.sues wi.h overfi.ti.g. Overfi.ti.g i. characteri.ed by a model’s learni.g that i. too closely fi.ted to the trai.i.g data, reduci.g i.s effecti.eness on unseen data. The problem of overfi.ti.g i. especi.lly prevalent i. medi.al i.age processi.g due to the hi.h costs and extensi.e ti.e requi.ed for i.age annotati.n, as well as the challenge of collecti.g substanti.l datasets that also respect pati.nt pri.acy concerni.g i.fecti.us di.eases such as pneumoni.. To mi.i.ate these challenges, thi. paper i.troduces the use of condi.i.nal generati.e adversari.l networks (CGAN) to enri.h the pneumoni. dataset wi.h 2690 synthesi.ed X-ray i.ages of the mi.ori.y class, ai.i.g to even out the dataset di.tri.uti.n for i.proved di.gnosti. performance. Subsequently, we appli.d four modi.i.d li.htwei.ht deep transfer learni.g models such as Xcepti.n, Mobi.eNetV2, Mobi.eNet, and Effi.i.ntNetB0. These models have been fi.e-tuned and evaluated, demonstrati.g remarkable detecti.n accuraci.s of 99.26%, 98.23%, 97.06%, and 94.55%, respecti.ely, across fi.ty epochs. The experi.ental results vali.ate that the models we have proposed achi.ve hi.h detecti.n accuracy rates, wi.h the best model reachi.g up to 99.26% effecti.eness, outperformi.g other models i. the di.gnosi. of pneumoni. from X-ray i.ages.

The Case for Stabi.i.i.g Chi.a's Exchange Rate:Setti.g the Stage for Fi.cal Expansi.n

引用

Chi.a & World Economy 2009年第1期17卷 1-32页

作者： ronald mckinnon Gunther Schnabl Stanford Uni.ersi.y Lei.zi. Uni.ersi.y

Chi.a＇s fi.anci.l conundrum ari.es from two sources. Fi.st, i.s large savi.g （trade） surplus results i. a currency mi.match because i. i. an i.mature credi.or that cannot lend i. i.s own currency. i.stead, forei.n currency clai.s （largely US dollars） bui.d up wi.hi. domesti. fi.anci.l i.sti.uti.ns. Second, economi.ts, both Ameri.an and Chi.ese, mi.takenly attri.ute the surpluses to an undervalued RMB. To placate the USA, the result was a gradual and predi.table appreci.ti.n of the RMB agai.st the dollar of 6 percent or more per year from July 2005 to July 2008. Together wi.h the fall i. US i.terest rates si.ce mi.-2007, thi. one- way bet i. the forei.n exchanges markets not only attracted hot money i.flows but i.hi.i.ed pri.ate capi.al outflows from fi.anci.g Chi.a＇ s huge trade surplus. Therefore, the People＇s Bank of Chi.a had to i.tervene heavi.y to prevent the RMB from ratcheti.g upwards, and so became the country＇s sole i.ternati.nal fi.anci.l i.termedi.ry as offi.i.l exchange reserves exploded Because of the currency mi.match, floati.g the RMB i. nei.her feasi.le nor desi.able, and a hi.her RMB would not reduce Chi.a＇ s trade surplus. i.stead, monetary control and normal pri.ate-sector fi.ance for the trade surplus requi.e a return to a credi.ly fi.ed nomi.al RMB/USD rate si.i.ar to that whi.h exi.ted between 1995 and 2004. However, for any newly reset RMB/USD rate to be credi.le as a monetary anchor, forei.n ＂Chi.a bashi.g＂ to get the RMB up must end. Then the stage would be set for fi.cal expansi.n to both sti.ulate the economy and reduce i.s trade surplus.
