i've been using tensorflow regression purposes. neural net small 10 input neurons, 12 hidden neurons in single layer , 5 output neurons. activation function relu cost square distance between output , real value my neural net trains correctly other optimizers such gradientdescent, adam, adagrad. however when try use adadelta, neural net won't train. variables stay same @ every step. i have tried every initial learning_rate possible (from 1.0e-6 10) , different weights initialization : same. does have slight idea of going on ? thanks much short answer: don't use adadelta very few people use today, should instead stick to: tf.train.momentumoptimizer 0.9 momentum standard , works well. drawback have find best learning rate. tf.train.rmspropoptimizer : results less dependent on learning rate. algorithm very similar adadelta , performs better in opinion. if want use adadelta, use parameters paper: learning_rate=1., rho=0.95, epsilon=1e-6 . bi

i confused between managed , unmanaged resources in .net programming. developing vb.net application. read in microsoft website that, if use managed resources garbage collector dispose , if use unmanaged resources need call dispose. didn’t answer following questions anywhere. how can differentiate resources used code “managed” , “unmanaged”? can have list of resources belonging managed , unmanaged resources? whether resources used/allocated before creation of objects or after creation of objects? in case of unmanaged resources whether resources disposed once scope gets closed or should dispose after closing of scope? if class inherits idisposable unmanaged or contains unmanaged not sure mean, @ ctor, creation of object, cant before, consider ctor after? (o.c. unless stated otherwise) best practice inheriting idisposable anywhere use managed code, .net having gc unless somehow lock unmanaged res. should ok.

i'm using facelets (jsf2.1) , i'm trying like: <c:foreach var="domainobject" items="#{mb.listofdomainobjects}"> <sec:authorize access="haspermission(#domainobject,'permission_x')"> hello world </sec:authorize> </c:foreach> i've tried changing #domainobject @domainobject , #{domainobject} , $domainobject , lot of other combinations same result: domainobject not processed correctly. error saying page cannot constructed, others domainobject null. it's scope tag c:foreach puts variable domainobject not scanned sec:authorize find it. i've tried force use of scope using tag <c:set ... scope="view"/> . i've tried use <ui:repeat> same results, considering tag sec:authorize jstl one, suppose executed in build time (like c:foreach ) , not in render time (like ui:repeat ) , think must use c:foreach , not ui:repeat . any chance solve problem?

i tried add own image switch control in xamarin forms using rendering concept unable override existing image.below code. in shared project added code this switch switcher = new extendedswitchnew(); and in ios [assembly: exportrenderer(typeof(extendedswitchnew),typeof(switchrenderernew))] namespace test.ios { public class switchrenderernew :switchrenderer { protected override void onelementchanged(elementchangedeventargs<switch> e) { base.onelementchanged(e); if (control != null) { uiimage imgon = uiimage.fromfile("images/switchon.png"); uiimage imgoff = uiimage.fromfile("images/switchoff.png"); control.onimage = imgon; control.offimage = imgoff; } } } } help me.thanks in advace.

i have function following signature: private void foo<tpoco>(icontext context, list<tpoco> pocos, datetime modifieddatetime) tpoco : myabstractclass and cannot find function in getmethods(). based on post ( getmethod generic method ), have tried these binding flags: gettype().getmethods(bindingflags.public | bindingflags.nonpublic | bindingflags.instance | bindingflags.static | bindingflags.flattenhierarchy ) and finds 14 other methods in class, not one. does find method: protected void bar<tcontext, tpoco>(list<tpoco> pocostopersist, tcontext context) tcontext : icontext, new() tpoco : myabstractclass so difference access level - can see other private functions. even if change binding flags simpler (which, understand, shouldn't make new items visible): gettype().getmethods(bindingflags.nonpublic | bindingflags.instance ) i still don't see function. as comments on post point out, code sh
