I see many ways like elbow method, silhouette score, they all define the cluster number after clustering.

Especially the elbow method, I need to monitor the relation with cluster number and find the elbow.

But if the dataset is too huge to let me find the elbow and I don't even how many cluster number actually.

Any way to pre-calculate number of cluster roughly?

thx
