tree-similarity
Compares two spectra using a tree similarity.
Installation
$ npm i ml-tree-similarity
Usage
import { createTree, treeSimilarity } from 'ml-tree-similarity';
const a = {
x: [1, 2, 3, 4, 5, 6, 7],
y: [0.3, 0.7, 4, 0.3, 0.2, 5, 0.3],
};
const b = {
x: [1, 2, 3, 4, 5, 6, 7],
y: [0.3, 4, 0.7, 0.3, 5, 0.2, 0.3],
};
// create a tree
const options = { from: 1, to: 7 };
const aTree = createTree(a, options);
const bTree = createTree(b, options);
const ans = treeSimilarity(aTree, bTree, options);
API Documentation
This algorithm was based in the following papers:
- A new method for the comparison of 1H NMR predictors based on tree-similarity of spectra
- Fast and shift-insensitive similarity comparisons of NMR using a tree-representation of spectra
