JIT Compilation

Just in time compilation that generates optimized machine code at runtime from high level graphs, accelerating ML workloads and smart contract VMs.

Joint Probability Distribution

Probability model over multiple random variables, capturing their dependence structure, foundation for graphical models and Bayesian inference.

Joint Embedding

Representation space learned for multiple modalities or objects so semantically related items lie close together, used in retrieval and cross modal search.

Jensen–Shannon Divergence

Symmetrized and smoothed version of KL divergence bounded between 0 and 1; used to compare probability distributions in GANs and topic models.

Jacobian Matrix

Matrix of first order partial derivatives of a vector valued function; central to backpropagation, sensitivity analysis, and normalizing flows.

Jaccard Similarity

Metric for set overlap defined as intersection over union; used for clustering, deduplication, and evaluating retrieval results.

JAX

High performance numerical computing library with composable transformations like JIT compilation, vectorization, and automatic differentiation, widely used in research and large model training.

Unlock Schedule

Timeline for when locked tokens become transferable, typically after cliffs and linear vesting, important for liquidity and sell‑pressure analysis.

Updatable Trusted Setup (ZK)

Trusted setup where participants can add new randomness later, so as long as one contribution is honest the toxic waste remains unknown even if others are compromised.

Universal Setup (ZK)

Trusted setup that works for any circuit within certain size bounds, so one ceremony can support many applications, unlike per‑circuit setups.
