Embeddings, high-dimensional numeric vectors representing input data features, are crucial in fields like computer vision and large language models, yet their complexity poses challenges for human interpretation. Dimensionality reduction techniques such as PCA, t-SNE, and UMAP address this by translating high-dimensional data into a more interpretable lower-dimensional space, each with unique strengths and weaknesses. PCA is efficient and straightforward but assumes linear relationships, while t-SNE excels at preserving local structure in nonlinear data but struggles with scalability. UMAP, which balances local and global structure, offers better scalability than t-SNE but depends on randomness and hyperparameters. These methods, illustrated using the CIFAR-10 dataset and models like ResNet-101 and CLIP, provide varied insights into data visualization. Additionally, custom methods, like Isomap and CompressionVAE, offer alternative approaches for dimensionality reduction, emphasizing the importance of choosing the right technique based on the specific data structure to gain meaningful insights.
