Availability (System Availability)
Measure of uptime and readiness of a system or service. In blockchains, relates to node liveness and data availability.
Augmentation (Data Augmentation)
Techniques that expand training data by transforming existing samples, improving robustness and generalization.
AutoML
Automation of ML tasks like feature engineering, model selection, and hyperparameter tuning.
Anomaly Detection
Techniques to spot unusual patterns in data, used for fraud detection, ops alerts, and model safety.
AUC (Area Under Curve)
Metric for binary classifiers representing area under the ROC curve. Higher is generally better.
Activation Function
Nonlinear function like ReLU or GELU that lets neural networks approximate complex relationships.
Actor‑Critic
Reinforcement learning architecture with a policy network (actor) and a value estimator (critic) that learn together.
ASI, Artificial Superintelligence
Hypothetical AI that vastly exceeds the best human minds across creativity, wisdom, and problem‑solving.
ANI, Artificial Narrow Intelligence
AI specialized for a specific task or domain, like image labeling or translation. Most deployed AI today.
AGI, Artificial General Intelligence
AI that can understand, learn, and apply knowledge across most tasks at or beyond human levels.
