i grid-search through cross-validation custom kernel svm using scikit-learn. more precisely following this example want define kernel function like def my_kernel(x, y): """ create custom kernel: k(x, y) = x * m *y.t """ return np.dot(np.dot(x, m), y.t) where m parameter of kernel (like gamma in gaussian kernel). i want feed parameter m through gridsearchcv , parameters = {'kernel':('my_kernel'), 'c':[1, 10], 'm':[m1,m2]} svr = svm.svc() clf = grid_search.gridsearchcv(svr, parameters) so question : how define my_kernel m variable given gridsearchcv ? you may have make wrapper class. like: class mysvc(baseestimator,classifiermixin): def __init__( self, # svc attributes m ): self.m = m # etc... def fit( self, x, y ): kernel = lambda x,y : np.dot(np.dot(x,m),y.t) self.svc_ = svc( kernel=kernel, # other parameters )

i'd write integration java program takes input file source directory, copies staging , writes result of processing output directory , removes temporary files staging . it's easy enough check output ok, there easy way check staging area being used correctly? 2 things come mind: monitoring folder file system events (any nice wrappers that?), or advanced permissions game (to allow create not delete). suggestions? thanks lot! n.b. java 6 on windows... assuming you're dead set on doing this, think easiest approach going checking file in staging folder after supposed have been copied , checking it's not there after it's supposed have been deleted. file f = new file(filepathstring); if(f.exists() && !f.isdirectory()) { /* */} how check if file exists in java?

i have program runs multiple tasklets using stackless python, , problem though fast, notice slowdown if start 1 or more processes run same code. for example, using threads inside processes takes program 6 seconds complete, , if start 2 processes still takes 6 seconds complete. if use tasklets program takes 2 seconds complete, takes 4 seconds if run 2 processes simultaneously , 6 seconds if run 3 processes , etc. my question is, normal behavior of stackless python? checked make sure tasklets in separate processes using separate schedulers , each process can see tasklets, maybe tasklets in processes still fighting on system resources? it's explanation can think of why each additional process cause slowdown when using tasklets not threads. need explain me can figure out if there's wrong code or if unavoidable issue.

is acceptable (or frowned upon) in javascript practice modify function parameter of type reference value (object) inside function? i’m aware of how works in function parameters passed value , reference value parameter pointer object’s memory location. thank you! edit: i've removed "pass reference" title , description make wording more correct , avoid confusion readers. correct answer (and helpful comments) still apply you seem know isn't passed reference, can't imagine "treating it" like. remember, because there no pass-by-reference in javascript, means can't reach out function , change variable value passed in (not object refers to). it's neither or bad practice; it's impossible. function foo(a) { = {"different stuff": "here"}; } var b = {stuff: "here"}; foo(b); // `foo`'s assignment `a` has nothing whatsoever // `b` , has no effect on console.lo

i'm not sure if i'm seeking possible, i'm checking make sure i'm not doing thing hard way. at moment have 2 sequences, both run @ same time. each sequence starts off waiting 3 seconds , 1 sequence scales node, other adjusts node's alpha. code looks this: node.runaction(skaction.sequence([animationwait, animationscale])) node.runaction(skaction.sequence([animationwait, animationalpha])) but there way of running both animationscale , animationalpha @ same time inside 1 sequence? (this doesn't work, i'm hoping can see i'm trying do): node.runaction(skaction.sequence([animationwait, (animationscale, animationalpha)])) you can group actions sequence: var actions = array<skaction>(); actions.append(skaction.sequence([animationwait, animationscale])); actions.append(skaction.sequence([animationwait, animationalpha])); let group = skaction.group(actions); node.runaction(group); when action executes, actions comprise group sta

i new git, , i'm confused. here's example: i build repo called prj in office. i add image , commit github later, when home, clone repo, check out new branch (let's call home ) , replace image 1 same name. then, after go office, delete old image, , update remote branch. seems work @ stage. i use git diff master origin/home , shows new node added image. however, when run git merge origin/home , image added @ home can not added local master. where did wrong? how can svn update? on office computer - don't delete image. reset local changes image file, pull. should see it's content update. if still don't see update, delete old image, commit deletion, try adding new image again. git weird replacing files have same name.

a ble peripherall send me data @ 5hz, receive in service send data through "local broadcast msg" ux @ same rateo after interpolation. on ux have draw custom indicator rateo. i think use surfaceview i'm wondering if normal view extension enough. can give me suggestion ? there's no fixed rate limit custom views. if planning render canvas, custom view more efficient surfaceview, because can take advantage of hardware acceleration . canvas rendering onto surfaceview surface done in software (as of 5.0 @ least). the advantage of surface that, because it's on separate layer, you're not tied view ui's invalidate/redraw cycle. at 5 updates per second think have pretty free hand in choosing solution.

i making simple game , stumbled upon problem. assume several points in 2d space. want make points close each other interact in way. let me throw picture here better understanding of problem: now, problem isn't computing distance . know how that. at first had around 10 points , check every combination, can assume, extremely inefficient increasing number of points. if had million of points in total, of them distant each other? i'm trying find suitable data structure or way @ problem, every point can mind surrounding , not whole space. there known algorithms this? don't know how name problem can google want. if don't know of such known algorighm, ideas welcome. you're still going have iterate through every point, there 2 optimizations can perform: 1) can eliminate obvious points checking if x1 < radius , if y1 < radius (like brent mentioned in answer). 2) instead of calculating distance, can calculate square of distance , compare square

i have int constants grouped in several enum, like: enum myenum{ object_a = 10, object_b = 13 }; now have several functions take enums , something, like: void myfunc(myenum e) { .... } in code, need use myfunc in both these 2 ways: myfunc(myenum.object_a); myfunc(13); this gives error because ints aren't casted enum implicitly. what recommend best practice preserving readability of code? an obvious solution use myfunc((myenum)13); boring because 1 needs cast int every time , code gets heavy. so far did (avoiding enums @ all): using echannelint = system.int32; public static class echannel { public static readonly int ch_connection = 10; public static readonly int ch_data = 50; } public void doit(echannelint ch) { .... } doit(echannel.ch_data); doit(10); which works, don't because seems "trick" or renaming thigs. suggest? perhaps "implicit operator" may useful? thank you you can overload myfu

currently i'm using aes/cbc encryption using javax.crypto.cipher library, however, i'm finding little slow. takes anywhere between 45s-1m decrypt 10 minute .mp4 video file. is there better way on android? i'm looking around , found posts openssl faster? any links, helpful posts and/or comments appreciated. use streaming instead of file decryption. if stream video can perform decryption of video need it. if use ctr or cbc mode can skip specific place within stream, although take additional tricks make happen. leaving decryption default provider should first choice, can speed things using native decryption library.
