MINING ALGORITHM
Clustering
Where to use it?
used in various applications such as market research and customer segmentation, biological data and medical imaging, search result clustering, recommendation engine, pattern recognition, social network analysis, image processing
How to use?
- first approach, start with classifying all data points into separate clusters
- then aggregating them as the distance decreases.
- In the second approach, all data points are classified as a single cluster and then partitioned as the distance increases
What it is?
Clustering is a method of partitioning a set of data or objects into a set of significant subclasses called clusters.
When to use?
Used when identifying and grouping similar data points in larger datasets without concern for the specific outcome
Decision tree
-
What it is?
A tree-like model that visualizes decisions and their possible consequences, implications, and costs as a decision assistance tool. The "branches" can then be simply analyzed and compared to determine the optimal procedure.
How to use ?
- Start with overarching objective or "big decision" at the top(root)
- Draw arrows
- Attach leaf nodes at the end of the branches
- Determine the odds of success of each decision point
- Evaluate risk vs reward
-
Evaluation Method
What it is?
Evaluation is a collection of research methods and methodologies with a specific goal. They give people a way to evaluate behaviors and activities using values, criteria, and standards. At the same time, evaluation is a method that aims to improve government and policy efficacy.
Where to use?
When establish a clear picture of performance and effect, evaluation should occur at regular intervals throughout the life of a project. Duration is affected by the type of system.
How to use it?
- Test
- Participation
- Data collection
