WebMay 11, 2014 · This problem seems to be pretty similar to a clustering problem, but the main difference is that we are concerned with a specific cluster size, but not concerned about the number of clusters. What I can think is to implement a "starvation" mechanism. If too much data point are assigned to a cluster, exceeding a critical value, then the … WebOct 20, 2024 · Differentiable Deep Clustering with Cluster Size Constraints. Clustering is a fundamental unsupervised learning approach. Many clustering algorithms -- such as -means -- rely on the euclidean distance as a similarity measure, which is often not the most relevant metric for high dimensional data such as images.
WebIn EM clustering, the algorithm iteratively refines an initial cluster model to fit the data and determines the probability that a data point exists in a cluster. The algorithm ends the process when the probabilistic model fits the data. ... That could happen if k means were set to run with no cluster size constraint. I'd love a solution that ...
