What is the best clustering algorithm for high dimensional data?

Graph-based clustering (Spectral, SNN-cliq, Seurat) is perhaps most robust for high-dimensional data as it uses the distance on a graph, e.g. the number of shared neighbors, which is more meaningful in high dimensions compared to the Euclidean distance.

What is clustering methods and high dimensional data?

Clustering high-dimensional data is the cluster analysis of data with anywhere from a few dozen to many thousands of dimensions.

Does Dbscan work for high dimensional data?

Grid-based DBSCAN is one of the recent improved algorithms aiming at facilitating efficiency. However, the performance of grid-based DBSCAN still suffers from two problems: neighbour explosion and redundancies in merging, which make the algorithms infeasible in high-dimensional space.

Is K means good for high dimensional data?

We all know that KMeans is great, that but it does not work well with higher dimension data.

What is high dimensional data in data mining?

High Dimensional means that the number of dimensions are staggeringly high — so high that calculations become extremely difficult. With high dimensional data, the number of features can exceed the number of observations. For example, microarrays, which measure gene expression, can contain tens of hundreds of samples.

What makes data high dimensional?

High Dimensional means that the number of dimensions are staggeringly high — so high that calculations become extremely difficult. With high dimensional data, the number of features can exceed the number of observations. One person (i.e. one observation) has millions of possible gene combinations. …

Can tSNE be used for clustering?

tSNE, (t-distributed stochastic neighbor embedding) is a clustering technique that has a similar end result to PCA, (principal component analysis). The focus of many clustering algorithms is to identify similarity in a high-dimensional dataset in such a way that dimensionality can be reduced.
