Webb聚类算法就很多了,比如我都尝试过minibatchKmeans、Kmeans3D、Kmeans、DBSCAN、AgglomerativeClustering、Birch。 但效果都不如Kmeans和minibatchKmeans。 最终就选择了这两种算法,聚类的效果差不多,K值最终选择是3。 Webb27 dec. 2024 · 已知:现有方案只有单机场景,应该只能在 Sklearn 的基础上优化 我的任务是要比库的方法有性能提升,看了几天源码,没有什么思路…达不到性能提升的话,这工作应该是悬了
Webb3. Compare BIRCH and MiniBatchKMeans. This example compares the timing of Birch (with and without the global clustering step) and MiniBatchKMeans on a synthetic dataset having 100,000 samples and 2 features generated using make_blobs. If n_clusters is set to None, the data is reduced from 100,000 samples to a set of 158 clusters. Webb2 dec. 2024 · I am using scikit-learn MiniBatchKMeans to do text clustering.

Webb10 juli 2015 · Here is the code. It's simply doing the following, for a dense and a sparse matrix: Create a 100K x 500 matrix. Fit a MinibatchKMeans estimator over the matrix (we don't care about the result) Display the time it took to fit the estimator. Between the two benchmarks, memory is manually garbage collected (to make sure we're on a fresh start).
