i'm working on school project and, between many tasks, need binarize fisher vectors following written in this paper . given vl_feat library use matlab , implementd simple tutorial return fisher vectors given features. everything works fine , updated vl_fisher function raise each dimension of fisher vector power of value α ∈ [0, 1] stated in section 4.1. α = 0 can have fisher vector values {-1,0,1} ternary encosing. the second part of section 4.1 explains how turn ternary encoding equivalent binary encoding. got little lost in there, due fact i'm using library return fisher vector representation. representation consists of vector of doubles , makes trickier follow paper description. so question is, how binarize fisher vectors vl_feat library on matlab ? have binarize ternary encoding ? should compute fisher vectors in way make them more suitable following binarization ? thanks in advance time! there 2 possible solutions problem: you put hand on open sou

i needed take array of (c#) integers , randomly reassign values make values "feel" more randomized, without changing length or sum of array. array can quite large, i'm wondering if has better way this. basically, array contains values sum divided length, 1 element having remainder. using is: static int[] addentropy(int[] ia) { int elements = ia.length; int sum = ia.sum(); (int runs = 0; runs < (elements * 2); runs++) { random rnd = new random(int.parse(guid.newguid().tostring().substring(0, 8), system.globalization.numberstyles.hexnumber)); int rndi = rnd.next(0, (sum / elements)); int rnde1 = rnd.next(0, elements); int rnde2 = rnd.next(0, elements); if (rndi < 1 ) rndi = 1; if (ia[rnde1] > (rndi + 2)) { ia[rnde1] = ia[rnde1] - rndi; ia[rnde2] = ia[rnde2] + rndi; } }

i have arduino connected pi via usb , sending readings dht sensor using simple program below (this bit works expected in arduino serial monitor): int chk = dht.read11(dht_pin); serial.println(dht.temperature,1); delay(2000); i have python program should data serial port: import serial conn = serial.serial('/dev/ttyacm0',9600) temp = conn.readline() print temp this script called in php using $temp = shell_exec('python temp.py 2>&1'); works fine values serial wrong. the expected output should 23.0 when refresh page (or run python script in terminal) values 2323.0 , 23.023.0 , 22..0 , 2 . these change time , come out in desired format. it seems if data serial overlapping, though serial.println() function puts on new line. if tell me how correct appreciated. try print repr(temp) ... or print temp.strip()+" .

i have vector this: 10 7 7 10 7 10 7 10 10 7 10 10 7 7 10 10 7 10 7 7 10 7 10 i want compare entries of vector in pairs: e.g. first entry second, third fourth until in pair have 2 equal entries. in example 2 equal values occur first time in sixth pair or in other words 11th , 12th values equal. important want have index of 11th row , continue comparison between 12th , 13th row. is there way (i prefer without looping)? edit: didn't explain myself clear enough. when pair has equal values delete first entry of these 2 values. indices of pairs not known start. in above example, desired output be: 10 7 7 10 7 10 7 10 10 7 10 7 7 10 10 7 10 7 7 10 7 10 and index of row has been deleted: 11 in case 1 row had deleted pairs consist of 7 , 10. based on edited version of question, it's clear need sort of looping function, because decisions on previous indices affect decisions on subsequent indices. efficient way can think populate logical

i have tableau connected cloudera impala data. table reading metastore keeps on updating so, when want viz update (pressing f5) have go impala in cloudera , execute "invalidate metadata" before refreshing viz. know can done using connection hive server 2, takes long time execute query. question there anyway automatically execute "validate metadata" , "refresh" queries in impala cloudera? thanks, amr unfortunately impala not offer mechanism automatically update metadata yet. working on future, though haven't committed such functionality particular release yet. in meantime, there may things can make easier. firstly, how table being updated? there new data files? if so, can run refresh faster. also, sure invalidate/refresh specific table, e.g. refresh my_table . see documentation [invalidate metadata][1] , refresh more information. is there etl process in background? users modify workflow issue refresh command impala after updating

currently have started use selenium 2.0/web-driver automation testing company work for. currently have 20 tests developed testing, when run tests open new browser window each test. unfortunately though need new user registration/login info executed in first test used in rest of tests since i'm testing webstore/shopping cart. my question is, there way either stop having new browser windows opening or close window , place focus first window new user registered , logged in? through doing research before writing question here found out driver.getwindowhandles(); which have being run in registration test case , driver.switchto().window("handle"); have being run in second test case , thought should have put focus first window. i'm using driver.close(); close additional windows being created, prefer don't open in first place. if understand question correct need - add procedure @before annotation , inside procedure open driver. add procedu

final list<string> userids = request.getuserids(); final list<string> keys = userids.stream().map(p -> { return removeprefix(p); }).collect(collectors.tolist()); basically, every key in list of userids contains prefix "_user" want remove every key. so, invoking removeprefix function on each item of list , storing result in list called "keys" yes it's fine although make little shorter , more readable method reference , static import: final list<string> keys = userids.stream() .map(this::removeprefix) .collect(tolist());

i trying automate html5 application checks @ location of real cursor before accepts click. tried using selenium in python automate clicks @ various points on canvas. buttons on canvas change color way supposed when mouse on them when selenium tries click on them, click accepted if have real mouse on same button @ time selenium trying click (i don't have click manually, hover mouse). so, thinking of using sikuli or autopy instead (both of have used great success in past). trouble is, both of these things move real cursor around, , don't want that. i wonder if possible disable mouse integration virtual machine in virtualbox, , use 1 of these tools move virtual machine's cursor, , automate applications inside virtual machine without affecting real cursor. know how this, or if possible? i have no experience selenium, maybe can make sikuli , selenium coorperate each other. 1 has wait() until parameter set. have 1 parameter, , when option "a" sikuli

is possible use breezejs ionic framework(mibile), planing develop mobile application using ionic , targeting using ionic love if ionic support use of breezejs, if have idea, please share experience. thanks.` breezejs works angular, there angular adapter breeze provides it. since ionic built on angular, ionic work breeze. built complex ionic app makes heavy use of breezejs caching data work offline.

alright; i'm finding odd memory leak when attempting use cvcreatemat make room soon-to-be-filled mat. below attempting do; adaptivethreshold didn't when put 3-channel image in, wanted split separate channels. works! every time go through particular function gain ~3mb of memory. since function expected run few hundred times, becomes rather noticeable problem. so here's code: void adaptivecolorthreshold(mat *inputshot, int adaptivemethod, int blocksize, int csubtraction) { mat newinputshot = (*inputshot).clone(); mat inputblue = cvcreatemat(newinputshot.rows, newinputshot.cols, cv_8uc1); mat inputgreen = cvcreatemat(newinputshot.rows, newinputshot.cols, cv_8uc1); mat inputred = cvcreatemat(newinputshot.rows, newinputshot.cols, cv_8uc1); for(int rows = 0; rows < newinputshot.rows; rows++) { for(int cols = 0; cols < newinputshot.cols; cols++) { inputblue.data[inputblue.step[0]*rows + inputblue.step[1]*cols] = n
