Kathleen Walch and Ron Schmelzer discuss the definitions of data, dataset, big data, and the DIKUW Pyramid, and how these concepts relate to AI. They emphasize the importance of analyzing data to gain insights and the challenges of big data. They also explain the progression from basic data to wisdom in the DIKUW Pyramid, and the importance of putting data into practice using the CPMAI methodology.
Analyzing data is necessary to gain insights and meaningful information for AI and machine learning systems.
The DIKUW pyramid highlights the importance of moving beyond basic data towards gaining deeper understanding and valuable insights in AI.

The Importance of Data and Data Analysis in AI
Data is essential for AI and machine learning systems to function. While data on its own does not provide meaning, analyzing it is necessary to gain insights and meaningful information. A data set is a collection of data with common attributes or context. Despite the basic nature of these concepts, understanding the distinctions is crucial to avoid confusion. Additionally, big data refers to data sets of significant size, complexity, and variable formats. However, big data is not solely defined by size, but also by the challenges it presents in terms of storage, processing, and analysis.
The DIKUW Pyramid
The DIKUW pyramid visually represents the increasing value derived from data. This pyramid includes five levels: data, information, knowledge, understanding, and wisdom. Data forms the base, while information provides details on the who, what, where, and when. Knowledge moves towards understanding the how, which is where machine learning is placed. Lastly, wisdom represents the pinnacle of human-level insights. The pyramid underscores the importance of moving beyond basic data towards gaining deeper understanding and valuable insights.
Translating Terminology into Practice
While defining terms is essential, it is equally important to understand how to apply them practically. The glossary series aims to provide a high-level understanding of AI, machine learning, and big data concepts. The CPMAI methodology is recommended as a comprehensive approach to implementing AI correctly. To further enhance knowledge and skills, CognitiveTica offers free introductory courses and CPMAI certification programs to enable individuals to succeed in AI endeavors.
Data is the heart of AI. So, of course we need to have a podcast about data! In this episode of the AI Today podcast hosts Kathleen Walch and Ron Schmelzer define the terms Data, Dataset, Big Data, DIKUW Pyramid.
Data is the basic unit of discrete values that convey meaning, facts, quantities, or other units that computers operate on for further processing, interpretation, and analysis.
