lingmodel-nodejs

Module for data series categorization, based on linguistic modelling approach. ##Installation Install module:

npm install lingmodel-nodejs

##Example Set dependency

var lingmodel = require('lingmodel-nodejs');

Initialize categorizer:

• Alphabet: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
• Intervalization method: equal intervals
• Number of derivatives: 10

var categorizer = lingmodel.getCategorizer('0123456789'.split(''), 'EQUAL', 10);

Train categorizer with linear function:

categorizer.train(
[
  {
    data : [1,3,5,7,9,11,13,15,17,19,21,23,25],
    name : 'y',
    category : 'Linear'
  }
]);

Train categorizer with quadratic and exponential functions:

categorizer.train(
[
  {
    data : [1,4,9,16,25,36,49,64,81,100,121,144,169],
    name : 'y',
    category : 'Quadratic'
  },
  {
    data : [1,2,4,8,16,32,64,128,256,512,1024,2048,4096],
    name : 'y',
    category : 'Exponential'
  }
]);

Categorize unknown function:

categorizer.categorize(
  {
    data : [-5,-6,-7,-8,-9,-10,-11,-12,-13,-14,-15,-16,-17,-18],
    name : 'y'
  }
).result;

Result: 'Linear'
