node-kleinberg-burst:Kleinbergs 突发检测的 JavaScript 实现

# node-kleinberg-burst ## Example ```javascript var burst = require('kleinberg-burst'); var offsets = [1, 2, 3, 10, 11, 12, 13, 14, 20, 25, 30]; burst(offsets) ``` ## Methods ```javascript var burst = require('kleinberg-burst') ``` ### var levels = burst(offsets, opts); `offset` is an array of occurrence time offsets. The function returns an array whose elements are the burst levels at the time of each occurrence. ## Options `opts.s = 2` - the base of the exponent used to determine event frequencies in a given state `opts.gamma = 1` - a coefficient modifies the cost of a transition to a higher state ## Install ``` $ npm i kleinberg-burst ``` ## See Also - Original paper is Kleinberg, J.
