kddbscan-rs
Rust implementation of the kddbscan clustering algorithm.
From the authors of kDDBSCAN algorithm.
Due to the adoption of global parameters, DBSCAN fails to identify clusters with different and varied densities. To solve the problem, this paper extends DBSCAN by exploiting a new density definition and proposes a novel algorithm called k -deviation density based DBSCAN (kDDBSCAN). Various datasets containing clusters with arbitrary shapes and different or varied densities are used to demonstrate the performance and investigate the feasibility and practicality of kDDBSCAN. The results show that kDDBSCAN performs better than DBSCAN.
Installation
Add kddbscan
as a dependency in your Cargo.toml
file
[dependencies]
kddbscan = "0.1.0"
Usage
Implement IntoPoint
trait on your point struct. And pass a vector of points to the cluster
function.
use kddbscan::{cluster, IntoPoint, ClusterId};
pub struct Coordinate {
pub x: f64,
pub y: f64,
}
impl IntoPoint for Coordinate {
fn get_distance(&self, neighbor: &Coordinate) -> f64 {
((self.x - neighbor.x).powi(2) + (self.y - neighbor.y).powi(2)).powf(0.5)
}
}
fn main() {
let mut coordinates: Vec<Coordinate> = vec![];
coordinates.push(Coordinate { x: 11.0, y: 12.0 });
coordinates.push(Coordinate { x: 0.0, y: 0.0 });
coordinates.push(Coordinate { x: 12.0, y: 11.0 });
coordinates.push(Coordinate { x: 11.0, y: 9.0 });
coordinates.push(Coordinate { x: 10.0, y: 8.0 });
coordinates.push(Coordinate { x: 1.0, y: 2.0 });
coordinates.push(Coordinate { x: 3.0, y: 1.0 });
coordinates.push(Coordinate { x: 4.0, y: 4.0 });
coordinates.push(Coordinate { x: 9.0, y: 0.0 });
let clustered = cluster(coordinates, 2, None, None);
}
