Areas this publication covers

Practical depth across the full conversational AI stack — from architecture to deployment.

  • Dialogue architecture

    State machines, flow graphs, and turn management for complex multi-step conversations.

  • Knowledge retrieval

    Vector stores, chunking strategies, and embedding selection for grounded AI responses.

  • Model fine-tuning

    When to fine-tune versus prompt-engineer, and how to prepare domain-specific datasets.

  • Evaluation and testing

    Metrics that matter for dialogue quality — beyond BLEU scores and perplexity.

  • Safety and guardrails

    Output filtering, jailbreak resistance, and responsible deployment patterns.

  • Integration patterns

    Connecting conversational agents to CRMs, APIs, and internal data sources reliably.
