Tutorials

These tutorials are task-oriented walkthroughs. Each one names the model shape, the inference route, and the point where the result should be inspected or validated.

What Each Tutorial Demonstrates

Tutorial	Main idea	Related guides
Fitting Heterogeneous Records	A tuple-shaped row becomes a composite estimator, and a mixture adds a latent cluster over the whole record.	Core Concepts, Structured Statistical Families
PPL Mixture Workflow	free parameters and Mix lower to the same estimator/distribution contract as the core API.	Probabilistic Programming, Automatic Inference
Enumeration and Ranking	A fitted model can expose ranked support traversal when the capability is available.	Enumeration and Ranking, Capabilities And Contracts
Production Artifacts	Fitted models need provenance, registry metadata, serving wrappers, and drift checks.	Production Workflows, Model Lifecycle
LLM Distillation Cascade	A teacher labels examples, a local model learns the task, and calibrated confidence decides whether to answer or escalate.	Task Distillation, Task Serving, Routing, And Edge Deployment
LLM Uncertainty	Repeated LLM samples become semantic entropy, answer confidence, and abstention decisions.	Uncertainty, Reasoning Systems
Representation And Model Families	Segmenters, embeddings, and vector quantizers turn heterogeneous modalities into a shared modeling stream.	Representation Layer, Model Families
Relations And Operations	Distribution operations and structured feasible-set solvers solve different parts of a decision workflow.	Operations, Relations
Evolution And Analysis	Diagnostics and objective-led search promote challengers only when they pass a verification gate.	Analysis Utilities, Evolution And Search
