G-CoMVKM

Globally Collaborative Multi-View k-Means Clustering

Overview

G-CoMVKM is a Python implementation of the Globally Collaborative Multi-View k-Means clustering algorithm, originally developed by Kristina P. Sinaga. The algorithm integrates a collaborative transfer learning framework with entropy-regularized feature-view reduction, enabling dynamic elimination of uninformative components. This method achieves clustering by balancing local view importance and global consensus.

Installation

You can install G-CoMVKM directly from PyPI:

pip install gcomvkm

Requirements

• Python 3.7+
• NumPy
• SciPy
• Matplotlib
• scikit-learn
• seaborn

Usage

from gcomvkm import GCoMVKM
from gcomvkm.utils import load_synthetic_data
from gcomvkm.evaluation import nmi, rand_index, adjusted_rand_index

# Load the dataset
X, label = load_synthetic_data()

# Create and fit the model
model = GCoMVKM(
    n_clusters=2,
    gamma=5.0,
    theta=4.0,
    max_iter=100,
    tol=1e-4,
    verbose=True,
    random_state=42
)

model.fit(X)

# Get the cluster assignments
predicted_labels = model.labels_

# Evaluate the clustering performance
nmi_score = nmi(label, predicted_labels)
ri_score = rand_index(label, predicted_labels)
ari_score = adjusted_rand_index(label, predicted_labels)

print(f"NMI: {nmi_score:.4f}")
print(f"RI: {ri_score:.4f}")
print(f"ARI: {ari_score:.4f}")

Algorithm Parameters

• n_clusters: Number of clusters to form
• gamma: Exponent parameter to control the weights of V (typically in range [0,1])
• theta: Coefficient parameter to control the weights of W (typically > 0)
• max_iter: Maximum number of iterations
• tol: Convergence tolerance
• verbose: Whether to print progress information
• random_state: Random seed for reproducibility

Features

• Multi-view clustering with feature and view weighting
• Automatic dimensionality reduction through entropy regularization
• Balanced local and global consensus clustering
• Comprehensive evaluation metrics
