Application of density-based clustering algorithm and
However, in the antimony flotation plant in the Hunan Province, the chemical testing for analyzing the antimony grade generated one labeled datum per hour. Still, it only worked 8 h in the daytime. Thus, there were only eight data points for chemical testing every day. The low frequency of chemical testing resulted in a small amount of data.
