In order to be able to cluster text data, we’ll need to make multiple decisions, including how to process the data and what algorithms to use. Selecting embeddings. First, it is necessary to represent our text data numerically. One approach is to create embeddings, or vector representations, of each word to use for the clustering.Furthermore, the reason for this abnormality is also a concern. It is obvious that minor clusters tend to be anomalies. In this manner, for instance, we might conclude that the clusters which represent smaller than 10% of the entire data are anomaly clusters. We expect that a few clusters will cover the majority of the data.2.3 Data redundancy. Dự phòng dữ liệu cũng là một điểm mạnh khi sử dụng Database Clustering.
