i want filter backbone models have multiple key/value paris equal. example, want match all/first model has id of 123 , name 'john'. i realize there other ways this, leverage matches() method. is possible use underscore's matches() method create function pass filter or find find backbone model? var search_fn = _.matches({id: 123, type: 'john'}); var should_be_active = _.find(master_model_array, search_fn); yes, should work, similar have done using "filter". to reiterate: // sample data var x = {name:"j", id: 1}, y = {name: "j", id: 2}, z = {name: "j", id: 1, more: "data"}, match = _.matches({name: "j", id: 1}); var list = [x,y,z]; var result = _.filter(list, match); this results in x , z matches criteria. jsfiddle hope helps.

i have image , extracting subimage feed neural network. attempting calculate average output of subimages in same neighborhood. so if have original image (m x n pixels) , found subimage @ (sub_x, sub_y) size (sub_width , sub_height), need extract subimages same size (sub_width , sub_height) @ (sub_x + m, sub_y + n) m , n go 1 - 3. i have working solution: for (int subx = (x-3); subx < (x+4); subx++) (int suby = (y-3); suby < (y+4); suby++) if ( (subx > 0) && (suby > 0) ) if ( ((subx + width) < img.getwidth()) && ((suby + height) < img.getheight()) ){ counter++; testingimage = img.getsubimage(subx, suby, width, height); } x,y, width, , height integers of original subimage found. img original full sized bufferedimage. i'm not happy performance though. there faster/smarter way this? here's 1 simple thing can do: rid of conditions inside loops. calculate ranges first, o...

does pandas have equivalent of r's na (meaning not available)? if not, convention representing missing value, opposed nan represents mathematically impossible value such divide zero? currently there no na value available in pandas or numpy. section "working missing data" in pandas manual ( http://pandas.pydata.org/pandas-docs/stable/missing_data.html ): the choice of using nan internally denote missing data largely simplicity , performance reasons. differs maskedarray approach of, example, scikits.timeseries . hopeful numpy able provide native na type solution (similar r) performant enough used in pandas. also, part of documentation ( http://pandas.pydata.org/pandas-docs/stable/gotchas.html#nan-integer-na-values-and-na-type-promotions ) provides more details on trade-offs in choice of na representation.

i'm new templates , trying use functions out of class adapt generic programming. wenn this: template<int c, int d> class a{ ... } float function(number<int c, int d> value); it leads following error: error: wrong number of template arguments (1, should 2) float function(number<int c, int d> value); ^ am missing here? you need define template arguments on function , forward them type: template<int c, int d> float function(number<c, d> value);

i have question: i'm dealing digitalwatch.sct state chart model right now. when bottom right pressed @ least 1.5 seconds, digital watch should switch time editing mode. how can manage it, kind of strategy or triggered event should do? the event bottom right pressing "buttons.bottomrightpressed". thank help. even though don't know details of statechart model 'blindly' suggest following steps: add state 'waitforeditmode' add transition state e.g. 'clockmode' waitforeditmode buttons.bottomrightpressed trigger add new event bottomrightreleased buttons interface add transition trigger buttons.bottomrightreleased waitforeditmode clockmode. add transition trigger 'after 1500ms' waitforeditmode 'editmode' of course there alternatives... one more hint: if post questions regarding yakindu statechart tools it's user forum should answers without 4 month delay ;) ...

i'm using python (numpy) , want plot roc curve given 1d noise histogram , 1d histogram signal+noise distribution. aware various libraries scikit-learn can generate roc curves, use supervised machine learning approach based on predicted vs. actual labels. instead have 2 numpy arrays: 1 discrete probability density function (histogram) of background noise distribution, , histogram signal+noise distribution. i'm not doing machine learning, instead want make roc curve 2 histograms. can scikit-learn or python library this? thanks

suppose have 2 bitset objects in java values as //<msb....lsb> b1:<11000101> b2:<10111101> how can compare b1 , b2 know value represented b1 greater b2 . are logical operators (>,<,==) overloaded bitset? or have write own implementation? update: found "the operator > undefined argument type(s) java.util.bitset, java.util.bitset" . there built-in way so? you can xor -ing 2 sets together, , comparing length of result lengths of bit sets: if xor empty, bit sets equal. can bypass operation calling equals() otherwise, length of xor result equal position of significant bit different between 2 values. whichever of 2 operands has bit set greater 1 of two. here sample implementation: int compare(bitset lhs, bitset rhs) { if (lhs.equals(rhs)) return 0; bitset xor = (bitset)lhs.clone(); xor.xor(rhs); int firstdifferent = xor.length()-1; if(firstdifferent==-1) return 0; return rhs.get(first...

i have sample project 3 uiviewcontroller want change uinavigationbar color each viewcontroller. i tried use code in viewdidappear method , not changing. [self.navigationcontroller.navigationbar setbackgroundimage:[uiimage imagenamed: @"bg.png"] forbarmetrics:uibarmetricsdefault]; in fact code setting background navigationbar, , true. if want set color each viewcontroller navigation bar, in viewcontroller1 (say first view controller) viewdidappear method add [self.navigationcontroller.navigationbar setbartintcolor:[uicolor greencolor]]; in viewcontroller2 (say second view controller) viewdidappear method add [self.navigationcontroller.navigationbar setbartintcolor:[uicolor bluecolor]]; then navigate through these controllers, see background color of navigation bar changed . but problem may not setting viewcontroller custom class, can set identity inspector.
