auto clustering

Im new to matlab. I want to know how auto clustering can be done in clustering ie, dynamic calculation of clusters. Can somebody explain me the steps in auto clustering.How it can be used in K-means or any other algorithm which provides efficient result.

Hi @Shivaranjani kamaraj,

As per my understanding of the question you would like to perform the auto-clustering on a dataset in MATLAB.

You can use the 'kmeans' function in MATLAB for clustering the dataset dynamically.

You can take help of the code below to start:

% Sample data generation (replace this with your actual data)
num_samples = 1000;
num_features = 2;
data = rand(num_samples, num_features);

% Parameters
num_clusters = 3; % Number of clusters
max_iterations = 100; % Maximum number of iterations

% Dynamic clustering loop
for iter = 1:max_iterations
    % Perform k-means clustering
    [cluster_labels, centroids] = kmeans(data, num_clusters);

    % Update previous centroids
    previous_centroids = centroids;
end

% Visualize clusters (for 2D data)
if num_features == 2
    figure;
    gscatter(data(:,1), data(:,2), cluster_labels);
    hold on;
    plot(centroids(:,1), centroids(:,2), 'kx', 'MarkerSize', 15, 'LineWidth', 3);
    legend('Cluster 1', 'Cluster 2', 'Cluster 3', 'Centroids');
    title('Dynamic K-Means Clustering');
    hold off;
end

Please note that for using the 'kmeans' function you must have the license for 'Statistics and Machine Learning Toolbox'.

You can explore more about the 'kmeans' algorithm using the documentation link mentioned below:

I hope that this will help!
