Dropout
Regularization technique that randomly disables neurons during training to prevent overfitting.
Deepfake
Synthetic media generated by AI that swaps or fabricates faces, voices, or scenes.
Deep Reinforcement Learning
Combines neural networks with reinforcement learning for agents that act in environments to maximize reward.
Decision Boundary
Surface in feature space that separates classes according to a model’s predictions.
Decoder‑Encoder Transformer
Sequence‑to‑sequence architecture with bidirectional encoders and autoregressive decoders, used in translation.
Decoder‑Only Transformer
Architecture used in LLMs that autoregressively predicts the next token with causal attention.
DID Method
Specific scheme such as did:ethr or did:key that defines how DIDs are created and resolved.
Deterministic Wallet
Wallet where all addresses are derived from a single seed using a standardized path scheme.
Derivatives (On‑Chain)
Contracts whose value derives from an underlying reference, such as perpetuals, futures, and options.
DeFi (Decentralized Finance)
Financial services built on smart contracts, including lending, exchanges, derivatives, and asset management.
