Data Mining Techniques
Data Mining Techniques
I have previously spoken about data analysis and the real world impact of it. Today, I discovered a website which highlighted the common data mining techniques which are used to discover hidden patterns and correlations is vast amounts of data, which is then used for decision making and predictive modelling.
Some of the most common data mining techniques I discovered are:
- Classification - A technique used to categorise data into predefined classes based on the data's features.
- Association Rule - Discovering interesting relationships or patterns among a set of items in transactional or market basket data. It helps identify frequently co-occurring items and generates rules to show associations between items, such as if X, then Y.
- Anomaly detection - Aims to identify unusual data instances that deviate significantly from the expected patterns. Some use cases may be detecting fraudulent actions or network intrusions.
- Clustering - To group similar data instances together based on their similarities to discover natural patterns or structures in the data without predefined classes.
- Time series analysis - analysing and predicting data points collected over time.
- Regression - To predict numeric values based on the relationship between input variables and a target variable to find a mathematical function or model that best fits the data to create accurate predictions from it.
