Abstract

The invention discloses a data cleaning method and device, a readable medium and electronic equipment. The data cleaning method comprises the steps of determining a neighborhood range of a target data point according to a preset range parameter; determining a neighborhood data set in the neighborhood range; the neighborhood data set comprises at least one neighborhood data point; determining a first reachable density of the target data point according to the target data point and each neighborhood data point; determining an outlier index of the target data point according to the first reachable density; and when the outlier index meets a preset condition, determining the target data point as an outlier data point, and performing cleaning processing on the outlier data point.

Description

technical field [0001] The invention relates to the field of data analysis, in particular to a data cleaning method, device, readable medium and electronic equipment. Background technique [0002] Using ocean tidal currents to generate electricity is a renewable and clean energy. Tidal current ocean energy has many advantages such as inexhaustibility, high energy density, and strong predictability. Therefore, it has received extensive attention and vigorous development in recent years, and is a hot spot in the field of new energy exploration. [0003] In the project of ocean tidal current power generation, the Internet of Things monitoring system developed based on big data and artificial intelligence technology can be combined to better cope with the complex marine environment and comprehensively monitor the working status of the equipment. [0004] It is understandable that the relevant data collected in the ocean tidal power generation platform is usually very complex, a...
