Abstract : In this work, we aim to study membership of four open clusters (NGC 1893, NGC 581, NGC 2264 and NGC 2354 ) using the DBSCAN (Density-Based Spatial Clustering of Applications with Noise) clustering algorithm based on the Gaia EDR3 Data. We select stars from the Gaia-EDR3 catalog, and construct a five-dimensional phase space (three-dimensional spatial position and two-dimensional proper motion) and obtain reliable cluster members. This data is then used for membership determination using machine learning. We obtain cluster parameters for our sample and compare it with the catalog values. The technique demonstrates the effectiveness of machine learning in membership determination of clusters.
