after you've trained model on mnist set, how can classify image having 2 digits? more generally, how train model detect number of digits on image? there hot field called "object detection" tries want. in general, can detect (digits, people, cars, etc) images , videos. the state-of-the-art techniques fall 2 categories: faster-rcnn , first proposes lot of candidate windows objects of interest , detects inside these windows. ssd , scans images once , detect objects, faster not reliable compared faster-rcnn. a well-known real-time object detection method yolo (you once), falls in ssd category, , has impressive real-time demo here , give sense of object detection. search these methods' names , find lot of example code satisfies needs. if looking digit detection, check out work surrounding stanford's house number dataset . however, note these works 5 , more years ago , not beat general methods faster-rcnn , ssd.

the first method tried caused error due disrupting layout, here issue: in have tableview cells have sliders/progress views. value on these sliders needs equal attached item (i assign rss items each cell, music)'s percent has downloaded, if user tapped download it. i calling func in observer download progress here: //download progress func urlsession(_ session: urlsession, downloadtask: urlsessiondownloadtask, didwritedata byteswritten: int64, totalbyteswritten: int64, totalbytesexpectedtowrite: int64) { let progress = double(totalbyteswritten) / double(totalbytesexpectedtowrite) print("\(downloadtask.originalrequest!.url!.absolutestring) \(progress)") updatelistcells() } here how try update cells user see progress bar gradually growing - have subclassed cells: func updatelistcells() { if let table = listvc.mytableview { if(!table.visiblecells.isempty) { v in table.visiblecells { l...

this question has answer here: r: generate repeating sequence based on vector 1 answer i need help. how create following vector sequence: 1 1 1 1 2 2 2 3 3 4 i tried use (rep) , (seq) still unsucessfull. try this: rep(1:4,4:1) output: [1] 1 1 1 1 2 2 2 3 3 4

doing assignment , stuck on few questions. t(n) = t(2n/5)+n t(n) = t(2n/3)+t(n/3)+n t(n) = t(n−2)+n something tells me on of them master theorem cannot applied. why? , upper bounds (big-oh)? the master theorem can applied recurrence of form t(n) = at(n / b) + o(n d ) where a, b, , d constants. (there other formulations, above 1 handles more common cases). specifically, means that the problem size must shrink constant factor, the subproblems must have same size, there must constant number of subproblems, and the additive term must polynomial. these criteria rule out second recurrence (the subproblems don't have same sizes) , third (the problem size must shrink constant factor). however, first recurrence satisfies 4 of these criteria. might rewrite recurrence as t(n) = t(n / (5/2)) + n. based on that, case of master theorem in, , recurrence solve to?
