c++ - How to judge the predict result of which SVM in opencv? -


for example have 2 svm objects svma , svmb, train different data set, , have sample sampc.

int idx  = svma.predict(sampc); int idx2 = svmb.predict(sampc);

how judge svm return similar result ? thanks.

this answered here, , in predict() doco (assuming have 2 class svm).

if call predict() again, , set parameter returndfval=true decision function value (the signed distance margin). can use judge result "better". bigger distance margin, more sample belongs class has been assigned.

elasticsearch python client - work with many nodes - how to work with sniffer -

i have 1 cluster 2 nodes. i trying understand best practise connect nodes, , check failover when there downtime on 1 node. from documentation : es = elasticsearch( ['esnode1', 'esnode2'], # sniff before doing sniff_on_start=true, # refresh nodes after node fails respond sniff_on_connection_fail=true, # , every 60 seconds sniffer_timeout=60 ) so tried connect nodes this: client = elasticsearch([ip1, ip2],sniff_on_start=true, sniffer_timeout=10,sniff_on_connection_fail=true) where ip1/ip2 machine ip's (for example 10.0.0.1, 10.0.0.2) in order test it, terminated ip2 (or put non existent if) now, when trying connect, get: transporterror: transporterror(n/a, 'unable sniff hosts - no viable hosts found.') even ip1 exist , up. if trying connect this: es = elasticsearch([ip1, ip2]) then can see in log if client not getting response ip2, move ip1, , return valid response. so missing here something? thought s...

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto...
