Study Notes
Machine Learning Categories
- Unsupervised learning is a category of machine learning.
- The other two main categories are supervised and reinforcement learning.
Unsupervised Learning Data
- Unsupervised learning algorithms use unlabeled data. This means the data doesn't have predefined categories or outputs.
Importance of Unsupervised Learning
- Unsupervised learning is crucial for discovering hidden patterns and structures in data.
- It helps in efficiently exploring large datasets.
- It saves data analysts time by automating the discovery of insights.
Unsupervised Learning in Network Models
- The main purpose in well-defined network models is to identify clusters or communities within the network.
- This is preferred by many analysts because it allows for the discovery of unknown relationships and structures within the data, without needing pre-defined labels.
- Algorithms use similarity measures (e.g., distance metrics) to group data points. This grouping reveals underlying relationships and helps define network structures.
Unsupervised Learning Definition
- Unsupervised learning is a machine learning technique that allows the algorithm to act on the data without prior training. It identifies patterns, relationships, and structures in unlabeled datasets.
