vb.net - Loop, aggregate and return unique DataRow sum -


i have datagrid contains multiple transactions of customer's buy ins. want add transaction buy ins each customer , add result on related images. have @ moment gives me logic errors i.e. adding same amounts on more 1 images.

here structure of datagrid (column titles): [name,surname, buyin, type, starttime, transactionid, customerid] , here code:

dim tbactiveplayers datatable = me.activeplayerstableadapter.getdata()  dim tbtemp new datatable  '   table = dataset.tables("orders")  ' declare object variable. dim objtotalbuyin object dim icount, ilbl integer ilbl = 1  dim viewuniqueplayers new dataview(tbactiveplayers) dim iactiveplayers integer = viewuniqueplayers.totable(true, "customerid").rows.count dim dtdatatable datatable = viewuniqueplayers.totable(true, "customerid")  dim mylabel label icount = 0 dtdatatable.rows.count     objtotalbuyin = tbactiveplayers.compute("sum(buyin)", "customerid = " & tbactiveplayers.rows(icount).item("customerid"))     'msgbox("name: " & tbactiveplayers.rows(icount + 1).item("name") & ", sumbuyin:" & sumobject.tostring & " resultcount:" & resultcount)     '     mylabel = ctype(me.controls.find("lblplayer" & ilbl, true)(0), label)     if not mylabel nothing         mylabel.text = "empty seat"     end if     '      mylabel.text = tbactiveplayers.rows(icount).item("name") & environment.newline & _                    "€" & objtotalbuyin.tostring      mylabel.image = global.pokerbusiness.my.resources.resources.seatocc     ilbl += 1  next

your filter function compute seems based off each row in tbactiveplayers, yet you're looping on each row (and counting rows of) view of unique players. brain compiler tells me might source of logic errors, because you're potentially computing sum filter that's using single, unique customer id more once. consider changing

objtotalbuyin = tbactiveplayers.compute("sum(buyin)", "customerid = " & tbactiveplayers.rows(icount).item("customerid"))

to

objtotalbuyin = tbactiveplayers.compute("sum(buyin)", "customerid = " & dtdatatable.rows(icount).item("customerid"))

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
