// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM
Feature Extraction
The process of transforming raw data into a set of features that are more informative and suitable for machine learning algorithms.
TECHNICAL DEFINITION
The process of creating new, more informative features from raw data by applying domain-specific knowledge or mathematical transformations (e.g., PCA, text embeddings, image filters), aiming to improve model performance and reduce dimensionality.
BACKGROUND
Generative Pre-trained Transformer 4 (GPT-4) is a large language model developed by OpenAI and the fourth in its series of GPT foundation models.
