javascript - selecting an optimal span -


this pure programming question. have array of words. words have pauses after them various length (mostly zero). each word has certainty score. want select optimal span of words lookahead window.

  • the lower overall certainty better (or lower 33th percentile of certainty better).
  • the longer pauses on edges better (with hard minimum).
  • there optimum length (like 5 seconds). closer better. there hard limits on mimimum , maximum length.

nota bene, in javascript, cannot afford using support vector machines s or like. :-) performance thoughts, calculated maybe every minute on window of 2-minute length (250 words or so).

second nota bene interested: select span of words generated automatic speech recognition manual transcription (active learning).

how approach this?

a night's sleep brought light on issue. there's little magic needed. since number of candidate spans quite limited (in worst case square of number of words in window -- 250^2), can evaluate fitness of each span , pick 1 best score.

duh, why didn't see yesterday?

javascript - Mootools wait with Fx.Morph start -

i trying var effect = new fx.morph(testmorph, { wait/delay 2 seconds before starting. ( fiddle here ) but when try .wait(2000) or .delay(2000) , or .wait(2000, effect) uncaught typeerror: object [object object] has no method 'delay' any ideas how working? code i'm using: var testmorph = document.id('testmorph'); var effect = new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start({ 'top': 20, 'opacity': 1 }).start({ 'border-color': '#a80025', 'color': '#a80025' }); effect.delay(2000); you can use combination of chain() , delay() achieve desired effect. new fx.morph(testmorph, { transition: 'back:out', duration: 900, link: 'chain' }).start().chain(function(){ this.start.delay(2000,effect,{ //first }); }).chain(function(){ this.start({ //second }); }); the
