// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM
Dimensionality Reduction
The process of reducing the number of features or variables in a dataset while trying to keep as much important information as possible.
TECHNICAL DEFINITION
Techniques employed to transform data from a high-dimensional space into a lower-dimensional space, aiming to mitigate the curse of dimensionality, reduce computational cost, and improve model performance by preserving essential data variance (e.g., PCA, t-SNE, UMAP).
BACKGROUND
A large language model (LLM) is a neural network trained on a vast amount of text for natural language processing tasks, especially language generation. LLMs can typically generate, summarize, translate and analyze text in many contexts, and are a foundational technology behind modern chatbots. Biased or inaccurate training data can make an LLM's output less reliable.
