**Neural Net Clustering** starts by initializing random centroids or cluster centers and then iteratively adjusts their positions based on the similarity of the data points. The similarity is measured using distance metrics such as Euclidean distance or cosine similarity. The process continues until convergence is achieved, and the clusters are well-defined.

*Neural Net Clustering* is an iterative process that adjusts the cluster centers based on the similarity of data points it computes.

How Does Neural Net Clustering Work?

Neural Net Clustering works by training a neural network with a set of input data points and their respective labels or cluster assignments. The neural network learns to identify patterns and similarities in the data, ultimately producing a model that can be used to assign new data points to the appropriate clusters.

1. Initially, random centroids or cluster centers are selected to represent the clusters.

2. The neural network computes the similarity between each data point and the centroids using distance metrics.

3. Based on the computed similarities, the data points are assigned to the nearest centroid, forming an initial set of clusters.

4. The neural network updates the centroid positions by considering the data points assigned to each cluster.

5. Steps 2, 3, and 4 are repeated until the centroids converge, resulting in well-defined clusters.

*Neural Net Clustering* not only forms clusters but also helps in discovering hidden patterns and relationships within the data.

Advantages of Neural Net Clustering

Neural Net Clustering offers several advantages that make it a valuable technique in data analysis and decision making:
