The following is a sample PPT framework that contains multiple topics. You can adjust and expand it according to your specific needs. Slide 1: Title Page Title: Data Mining: Discovering the Value Behind Data Subtitle: Mining Knowledge from Massive Data Your Name/Position/Organization Date Image: The image of a magnifying glass focusing on a data ball represents mining value from data. Speaker's Notes: Hello everyone, I am very happy to share knowledge about data mining with you today. Data mining, in simple terms, is the process of extracting implicit, previously unknown, and potentially valuable information from a large amount of data.


Just like panning for gold in a gold mine, we need to Special Data use a series of tools and techniques to mine valuable information from a large amount of data to support our decision-making. Slide 2: What is Data Mining? Definition: Data mining is the process of extracting implicit, previously unknown, but potentially useful information and knowledge from large amounts of incomplete, noisy, fuzzy, random, and complex data. Objectives: Classification: Assign data items to known categories. Prediction: Predict future trends based on known data.



Clustering Grouping data items into clusters with similar characteristics. Association rule mining: Discovering associations between different variables. Anomaly detection: Discovering data that is different from the majority of data. Image: A funnel-shaped chart showing the process of data from its original state to knowledge discovery. Speaker's notes: The goal of data mining is to make data "speak" to help us better understand the data and discover the laws and patterns in it.
