could explain me how use svm regression in opencv c++? regression should return value, value position in images(coordinates x , y)? or single number? i have use in video analysis. have 3 points of know trajectories along whole video. use trajectories of 2 of them infer trajectory of third one. train svm these trajectories. i thinking organize training data , labels that: training data: position(x,y) in each frame of 2 of points labels: position(x,y) of third point in each frame is proper way? or should organize that: training data: position(x,y) in each frame of 3 points add negative example, changing position of third point, simulate false training set labels: 1 if third point position belong trajectory, -1 if belongs false training set svm can used regression: see here http://alex.smola.org/papers/2003/smosch03b.pdf may problem more suitable multivariate rvm see here (with c++ source): http://mi.eng.cam.ac.uk/~at315/mvrvm.htm here opencv edition of cod...

for cakephp app i'm thinking database table names follow cakephp naming conventions. many times come across general table contains information not entity on it's own contains additional entity information. information in table intended re use placed apart main entity table. for example: work products can master products. in case table "products" link table "master_product_information" information don't want in "products" table. another example: table contains meta data of multiple pages. name table "pages_metadata", cake needs plural , "pages_metadatas" doesn't seem right. once again go "pages_metadata_information". how name tables not contain entities? [entity]_information one? i hope hear recommendations. thanks. the right answer (imo) go cakephp conventions - life easiest way, if have occasional awkward table name. in case, i'd name "master_product_information" table ma...

this question of possible , should try it? i have 2 rows in table 1 named jobs , 1 named contacts (hope still me) in jobs have following columns typeofjob id name phone address budget due in contacts have following columns id name phone address is there way sync 2 tables rows? id name phone address i ask make life lot easier me worried id might conflict and happens if delete user contacts want deleted row i new , learning if can answer me simplify answers great treat trying explain nan or something, on other hand might pick faster :) what want id in 1 of columns id of row in table. so, add column contact_id in jobs table, under assumption each contact potentially spawn multiple jobs. can query it, such select * `jobs` `contact_id` = 'whatever' you use joins more complex , efficient work (remember, less trips database, better!).

while using mock library, i've encountered situation calling my_mock.reset_mock() method returns new mock instance instead of resetting my_mock . apparently i'm somehow masking mock.reset_mock() , cannot figure out how happened. sample run (python 2.7): >>> mocks.normal_mock.mock_calls out[6]: [] >>> mocks.normal_mock.reset_mock() >>> mocks.normal_mock.mock_calls out[8]: [] >>> mocks.abnormal_mock.mock_calls out[2]: [] >>> mocks.abnormal_mock.reset_mock() >>> <magicmock name='abnormal_mock.reset_mock()' id='157604104'> >>> mocks.abnormal_mock.mock_calls out[4]: [call.reset_mock()] any idea cause this? additional info: all mocks encapsulated in designated class, instantiated once, , reset between test in unittest.testcase.teardown() . all mocks created calling patch.start() on patched object/method/module both normal , abnormal mocks in example mock-out module imported uut (...

i try send sms in service.if sms not sent means restart service after time, using timer.if sms sent means want stop timer,for stop timer use timer.cancel(); before i've check timer running or not.how check it?. int resultcode = getresultcode(); switch (resultcode) { case activity.result_ok: timer.cancel();//here want check timer running or not break; case smsmanager.result_error_generic_failure: timer_run(); break; case smsmanager.result_error_no_service: timer_run(); break; case smsmanager.result_error_null_pdu: timer_run(); break; case smsmanager.result_error_radio_off: timer_run(); break; ...

i have problem find minimum possible depth of graph implies have find maximum depth each node , return least of them all. simple dfs each node trick when things crazy extremely large input, dfs becomes inefficient (time limit). tried keeping distance of each leaf node being explored in memory didn't much. how efficiently find minimum depth of large graph. worthy of note graph in question has no cycle . to find graph centre/center of undirected tree graph could: do dfs find list of leaf nodes o(n) remove these leaf nodes graph , note during deletion new nodes become leaf nodes repeat step 2 until graph deleted the node/nodes deleted in last stage of algorithm graph centres of tree. each node deleted once, whole process can done in o(n).

i'm new rest design i'd pointers here. here have far: get /api/users //all users /api/users/123 //specific /api/users/me //get own profle post /api/users/me/session //start new session (login) delete /api/users/me/session //ends current session (logout) i'm wondering session / login/out stuff here. thinking correct here or should designed in other way more rest'ish? also, register user, should be: post /api/users even if starts new session? i recommend avoid term session , use auth (as in authentication). term session gives impression of server-side session goes against rest. the following good: get /api/users //all users /api/users/123 //specific /api/users/me //get own profile for authentication, may have this: post /api/auth //username/password required. auth_token sent delete /api/auth ...

i've been reading lot on , still 30+ seconds per query, while i'm should work lot faster. the problem this: having large linking table (40 millions rows, data consisting of 650mb , index representing 1.8 gb) defined follows: create table if not exists `glossary_entry_wordlist_1` ( `idterm` mediumint(8) unsigned not null, `idkeyword` mediumint(8) unsigned not null, `termlength` smallint(6) not null, `termnumberwords` tinyint(4) not null, `termtransliteralrfc` mediumint(9) not null, `keywordlength` tinyint(3) unsigned not null, `termlanguage` tinyint(4) not null, primary key (`idkeyword`,`idterm`), key `termtransliteralrfc` (`termtransliteralrfc`), key `termlength` (`termlength`), key `secondprimary` (`idterm`,`idkeyword`) ) engine=myisam default charset=latin1 collate=latin1_general_ci and small temporary table defined follows: create temporary table if not exists `foundids` ( `searchid` int(11) not null, `searchedkeywordid` int(11) not nu...
