Clustering algorithms can have a tough time when the features are not well designed. Here are some common problems they face:
High Dimensionality: When there are too many features, it can make it hard for the algorithm to find clusters. This is often called the "curse of dimensionality."
Irrelevant Features: If there are extra or noisy features, they can trick the algorithm into making wrong groups.
Data Imbalance: If some data is represented a lot more than other data, it can lead to incorrect cluster results.
To solve these problems, it’s really important to focus on creating strong features. Here are some helpful methods:
Dimensionality Reduction: Techniques like PCA (Principal Component Analysis) can help make the data less complicated by reducing the number of features.
Feature Selection: By choosing only the important features and removing the unnecessary ones, we can improve the quality of our clusters.
Normalization: This means adjusting the features so that they are on the same scale. This way, differences in ranges won't mess up how the clusters are formed.
