There has been a significant increase in the number of part-time workers last 3 years. Data collected from sakernas BPS showed that was 125,443,748 second period 2016. This rapidly increased 2017, 2018 and 2019 same period, by 128,062,746, 131,005,641, 133,560,880 workers. Based on years, East Java province highest use internet. research aims to determine internet using k-affinity propagation (...

This paper assesses the coherency in power systems employing affinity propagation (AP) algorithm with different distance metrics and quality measurements. assessment allows determining appropriate metric to cluster a frequency dataset that possesses coherent patterns. Thanks AP method does not require initialization for number of clusters, its convergence characteristics guaranteed by optimizat...

Recently a new clustering algorithm called ‘affinity propagation’ (AP) has been proposed, which efficiently clustered sparsely related data by passing messages between data points. However, we want to cluster large scale data where the similarities are not sparse in many cases. This paper presents two variants of AP for grouping large scale data with a dense similarity matrix. The local approac...
