Aspect	Description
Definition	A representation of data in fewer dimensions compared to the original space.
Techniques	- Principal Component Analysis (PCA) - t-Distributed Stochastic Neighbor Embedding (t-SNE) - Uniform Manifold Approximation and Projection (UMAP)
Latent Variables	Variables not directly observed but inferred from the observed data, capturing hidden structures.
Applications	- Autoencoders - Generative Models (e.g., VAEs, GANs) - Clustering and Classification
Benefits	- Efficiency: Reduced computational cost - Interpretability: Easier to understand and visualize - Noise Reduction: Removes irrelevant features
Challenges	- Information Loss: Potential loss during dimensionality reduction - Choice of Technique: Crucial for preserving important data features
