this question libsvm or svms in general. wonder if possible categorize feature-vectors of different length same svm model. let's train svm 1000 instances of following feature vector: [feature1 feature2 feature3 feature4 feature5] now want predict test-vector has same length of 5. if probability receive poor, want check first subset of test-vector containing columns 2-5. want dismiss 1 feature. my question is: possible tell svm check features 2-5 prediction (e.g. weights), or have train different svm models. 1 5 features, 4 features , on...? thanks in advance... marcus you can remove features test points fiddling file, highly recommend not using such approach. svm model valid when features present. if using linear kernel, setting given feature 0 implicitly cause ignored (though should not this). when using other kernels, no no. using different set of features predictions set used training not approach. i suggest train new model subset of features wish use ...

let's have 2 lists in r, not of equal length, like: <- list('a.1','a.2', 'a.3') b <- list('b.1','b.2', 'b.3', 'b.4') what best way construct list of interleaved elements where, once element of shorter list had been added, remaining elements of longer list append @ end?, like: interleaved <- list('a.1','b.1','a.2', 'b.2', 'a.3', 'b.3','b.4') without using loop. know mapply works case both lists have equal length. here's 1 way: idx <- order(c(seq_along(a), seq_along(b))) unlist(c(a,b))[idx] # [1] "a.1" "b.1" "a.2" "b.2" "a.3" "b.3" "b.4" as @james points out, since need list back, should do: (c(a,b))[idx]

i working on library needs date math extremely quickly. using jon skeet's noda time library, uses tick math, , extremely quick, want elapsed seconds in way faster casting noda time instant or duration timespan. the fastest way have been able far using ticks * 1e-07, thinking bit shifting might work faster (since 1e-07). in advance thoughts! don't cast timespan - take ticks , divide nodaconstants.tickspersecond . it's integer division, , very, quick. given 10 7 isn't power of 2 (or particularly neatly represented combinations of them) suspect you'd best off dividing. i'd surprised if division really proved bottleneck in code. while i'm trying keep noda time quick, i'm not above performing division or 2 appropriate :) if need partial seconds, i'd tempted divide tickspermillisecond instead, , use integer number of milliseconds rather using floating-point arithmetic. if need double elsewhere, of course, that's not going m...
