Data mining is a multi-disciplinary field that bridges the gap between several domains such as machine learning, artificial intelligence, data mining technologies, statistics, and others. Fundamentally, it is a process that involves extracting previously unknown and useful information or knowledge, often referred to as patterns, from large datasets.
In practical applications, data mining enables sectors to derive actionable insights from vast amounts of data. For instance, in the marine perception department, data mining is utilized to identify patterns from sensor data streams. The types of sensors employed include aerial footage from drones, optical sensors, infrared sensors, multispectral cameras, and laser scanners. This data mining helps assess various environmental hazards in aquatic environments, including plastic litter, oil spills, and other pollutants.
Data mining is a key element of the broader "Knowledge Discovery from Data" (KDD) process. Although the depiction presented here is simplified, the actual process comprises several steps:
By employing these methods, sectors like the marine perception department can monitor environmental health and address issues proactively. Data mining remains integral to converting raw data into meaningful insights.
I hope this article has provided you with a clear understanding of what data mining entails. Stay tuned for upcoming content on related topics such as predictive analytics and data stream mining.
Q: What is data mining? A: Data mining is a process of extracting previously unknown and useful information or patterns from large datasets, drawing from fields such as machine learning, artificial intelligence, and statistics.
