i using code in tutorial http://www.raywenderlich.com/76735/using-nsurlprotocol-swift in tutorial code caching every single request. my question when , how can clear entity of caching (core data)? or dont need clear caching entity? caching entity entity save data requested nsconnection. if need clear cache in core data how can choose data stay , others deleted. for example , making news app. every vc has label such title, date, category , uiwebview. , when app closed want delete caching links except "saved news". "saved news" category users choose tapping button "plus". i thinking create new column named "istosave". so, when user taps button save. need parse content text , pull out links (src=) , in coredata set column "istosave "to true. when app closed delete links column "istosave" = false so shortly: practice clear entity "cacheurls" , if yes how can clear urls selection ? here code: import ...

assume have 4 transactions a,a,a,b. assume, has been grouped b single group. there similar transactions c,c,g,c,c,c , c,c,b,c , c,c,b,c,c grouped. here see c has been grouped b , g c&b have been grouped twice compared c&g there lots of transactions these. when new set of transactions come c,c,b,a,a,g need suggest each of these transactions, other transactions should paired with. in example, prediction should follows. c -> b (predicted since had max probability) c -> b (predicted since had max probability) b -> c (predicted) -> b (predicted) -> b (predicted) g -> c (predicted) 1) simple case approach/ ml technique needed achieve this? 2) if transactions become more complicated a,a,a,b,n grouped, how able handle case. i can go through transactions , calculate probability of each transactions in group, there better approach should considering. packages available these problems?

is there standard function can applied single vector process 2 elements per step? for example, have vector: > <- c(8, 4, 5, 5, 7, 10) and want subtract 2 neighbors elements: > func(a, function (x1, x2) { x1-x2 }) [1] 4 -1 0 -2 -3 in general if want process consecutive vector elements in pairs can first element in each pair with: (first <- head(a, -1)) # [1] 8 4 5 5 7 and can second element in each pair with (second <- tail(a, -1)) # [1] 4 5 5 7 10 then can perform operation want on consecutive elements. instance, here's operation: first-second # [1] 4 -1 0 -2 -3 here's product of consecutive elements: first*second # [1] 32 20 25 35 70 note operation pretty common there specialized function take differences of consecutive elements, diff .
