Remember we care about intra-cluster similarity in K-means and this is what an elbow plot helps to capture. plt.plot(K, sum_of_squared_distances, 'bx-') plt.xlabel('k') plt.ylabel('sum_of_squared_distances') plt.title('elbow method for optimal k') plt.show() Here we can see th...
Ward’s method:uses minimumvariancein each step to create relatively small, even-sized clusters. K Means Clustering Clustering is just a way to group a set of data into smaller sets. The two ways you could group a set of data are quantitatively (using numbers) and qualitatively (using categ...

We propose two new algorithms for clustering graphs and networks. The first, called K‑algorithm, is derived directly from the k-means algorithm. It a
The knowledge that you have emerged wiser and stronger from setbacks means that you are, ever after, secure in your ability to survive. You will never truly know yourself, or the strength of your relationships, until both have been tested by adversity. Such knowledge is a true gift, for al...

Optimized the averaging step of K_means to use non-moving averages and arrays instead of hashmaps. The code also updates the new centroid in-place. Also fixed deprecation warning on all benchmarks in linfa-clustering (other benchmarks may have the same warnings). I'm curious as to the...
