External Knowledge Tooling
Systems for augmenting LLMs with search, retrieval, or code execution to ground answers in fresh data.
Explainable AI (XAI)
Techniques that make model predictions interpretable, e.g., SHAP, LIME, saliency maps.
Evaluation Metric
Quantitative measure of model performance, such as accuracy, F1, BLEU, ROUGE, or perplexity.
Early Stopping
Regularization technique that halts training when validation performance stops improving.
Entropy (Information Theory)
Measure of uncertainty in a probability distribution; also used to describe randomness in cryptographic keys.
Ensemble Learning
Combining multiple models to improve accuracy and robustness, e.g., bagging, boosting.
Encoder
Neural network component that maps inputs to latent representations; often bidirectional in Transformers.
Embedding Model
Model that converts inputs to vector embeddings used for search, clustering, or retrieval‑augmented generation.
Embedding
Dense vector representation of text, images, or audio capturing semantic relationships.
Gas Price / Base Fee
Per‑unit cost of gas; the base fee is burned under EIP‑1559 while tips incentivize inclusion.
