i'm total beginner regarding a.n.n.s. understand concept , there's no straight explanation why input series of 0s , 1s , output series of 0s , 1s. i read here on neural networks - input values can encode input data normalization function it's converted number between 0 , 1. is case or misunderstanding things? also think point me in right direction regarding article/ lecturing material should pick clear things out? i'm relearning nets now, , asked similar question. it's hard know exact scenario is, me, activations in range of 0-1 because activation function sigmoid function, outputs in range of 0-1 (although you'll need ask math oriented person why is). say you're using simple step function instead activation function. logically take 0 or 1 (but nothing in between), , output 0 or 1. so answer seems be: range of activations in net defined activation function used. my similar question.

i learning c "the c programming language" , have ran getchar() confuses me. apparently, when call getchar() in program, input text stored in buffer , getchar() reads characters in buffer 1 one until sees eof . possible me instruct getchar() perform process second time on same buffer? instance, second loop in following program not run me. possible "reset" getchar() after first loop? #include <stdio.h> int main() { int c,d; c = d = 0; while((c = getchar()) != eof) printf("foo"); while((d = getchar()) != eof) printf("bar"); } it's not getchar() buffered, terminal. once hit enter , terminal sends whole line typed at once program. program's point of view, there's no buffer, sat still ten seconds, typed whole sentence in blink. you can verify crafting loop getchar() 's, , outputs character received : output not interleaved input, appear once you've pressed enter . thus, if want reuse know bu...

in matlab's mex files there function mxisscalar tells if input mex files scalar or not. function has been introduced in r2015a. if using previous version of matlab (2014b in case, if matters), elegant way of checking if input scalar or array? do need combine mxgetnumberofdimensions , mxgetdimensions , mxisnumeric it? or there other clear , simple way of doing it? favor readability on speed. mrows = mxgetm(prhs[0]); ncols = mxgetn(prhs[0]); if (mrows==1 && ncols==1) { // scalar prhs[0] here } note that, if prhs[0] has more 2 dimensions n, mxgetn result of product of dimensions 2 ... n. mxgetm return first dimension. may not check sparse matrices these may not return actual number of elements in matrix. a full example mex file can found @ http://www.mathworks.com/help/matlab/matlab_external/passing-a-scalar_btgcjh1-1.html .

i rid of "return" function of keyboard while user typing, there no new lines, instead 'return' key function 'done' hide keyboard. i using uitextview, editable, user able type post, , post main timeline, since have fixed cells, don't want user able press 'return' , post out of range of timeline. i found works uitextfield, not uitextview: func textfieldshouldreturn(textfield: uitextfield!) -> bool { textfield.resignfirstresponder() //if desired return true } so wanted know if there way in uitextview, or @ least able hide keyboard if pressed return, instead of creating new line. you can set return key type of text field: textfield.returnkeytype = uireturnkeytype.done update can use same approach set return key "done", mentioned above. however, uitextview doesn't provide callback when user hits return key. workaround, can try handle textview(textview: uitextview, shouldchangetextinrange range: nsrange...
