Data reduction and projection: Finding useful features to represent the data depending on the purpose of the task.Data cleaning and preprocessing:Basic operations include removing noise if appropriate, collecting the necessary information to model or account for noise, deciding on strategies for handling missing data fields, and accounting for time sequence information and known changes.Creating a target data set: Selecting the data set or focusing on a set of variables or data samples on which the discovery was made.Goal identification: Develop and understand the application domain and the relevant prior knowledge and identify the KDD process's goal from the customer perspective.Knowledge discovery in the database process includes the following steps, such as: KDD is usually used to answer questions like what are the main products that might help to obtain high-profit next year in V-Mart. This is achieved by creating short reports, modeling the process of generating data, and developing predictive models that can predict future cases.ĭue to the exponential growth of data, especially in areas such as business, KDD has become a very important process to convert this large wealth of data into business intelligence, as manual extraction of patterns has become seemingly impossible in the past few decades.įor example, it is currently used for various applications such as social network analysis, fraud detection, science, investment, manufacturing, telecommunications, data cleaning, sports, information retrieval, and marketing. This process deals with low-level mapping data into other forms that are more compact, abstract, and useful. KDD is the whole process of trying to make sense of data by developing appropriate methods or techniques. KDD is a computer science field specializing in extracting previously unknown and interesting information from raw data. Nonetheless, KDD and Data Mining are used interchangeably. Data Mining is the application of a specific algorithm to extract patterns from data. KDD consists of several steps, and Data Mining is one of them. KDD (Knowledge Discovery in Databases) is a field of computer science, which includes the tools and theories to help humans in extracting useful and previously unknown information (i.e., knowledge) from large collections of digitized data.
