The six layers are SENSE (sensors and data acquisition), CONNECT (communication and data pipelines), COMPUTE (edge and cloud processing), REASON (AI agents and decision engines), ACT (autonomous control systems), and ORCHESTRATE (software-defined coordination). Most AI consulting stops at REASON; most production failures live in ORCHESTRATE.

Pilot Project

A limited real-world deployment of an AI solution that tests performance, gathers user feedback, and refines the approach before broader rollout. A successful pilot de-risks the full investment and builds organisational confidence in AI.

Positional Encoding

A technique that injects information about the position of each token in a sequence into the transformer, compensating for the architecture's lack of inherent sequence awareness. Modern models use learned or rotary positional encodings (RoPE) to support long context windows.

Post-Market Monitoring

The ongoing collection and analysis of data about a deployed AI system's real-world performance and risk profile, required for high-risk AI systems under the EU AI Act. Providers must proactively detect and report incidents, model drift, and new risks throughout the product's lifecycle.

Production AI

AI systems that are live in enterprise environments, processing real transactions and influencing business decisions at scale. Production AI requires robust MLOps practices, monitoring, compliance controls, and SLAs—a significantly higher bar than prototype or pilot systems.

Prohibited AI

AI practices banned outright under the EU AI Act because they pose unacceptable risks to fundamental rights or democratic values. Banned uses include real-time biometric surveillance in public spaces, social scoring by public authorities, subliminal manipulation, and exploiting vulnerable groups.

Prompt Cache

A technique that caches the key-value (KV) attention states of a repeated prompt prefix, so subsequent requests reuse the pre-computed computation rather than re-running it. Prompt caching reduces latency and cost significantly for applications with long system prompts.

Prompt Engineering

The practice of designing and optimising input prompts to elicit the best results from AI models, especially LLMs. Structured prompting—using system instructions, examples, and constraints—can dramatically improve output quality without changing the underlying model.

Proof of Concept (POC)

A small-scale implementation that demonstrates the technical feasibility of an AI solution without full production investment. POCs validate whether a chosen approach can work before committing resources to pilot and production phases.

Purpose Limitation

The GDPR principle that personal data must be collected for specified, explicit, and legitimate purposes and not further processed in a way incompatible with those purposes. This constrains organisations from repurposing customer data to train internal AI models without fresh consent or a lawful basis.

Quantization

A model compression technique that reduces the numerical precision of model weights—for example, from 32-bit floats to 8-bit integers—shrinking memory requirements and accelerating inference with minimal accuracy loss. Quantization is essential for deploying LLMs on-premise or at the edge.

Ray Serve

An open-source, scalable model serving framework built on the Ray distributed computing library. Ray Serve supports complex inference pipelines with model composition, dynamic batching, and Python-native deployment, making it popular for LLM serving.

Real-Time Inference

Serving model predictions with low latency in response to individual live requests, typically within milliseconds to seconds. Real-time inference is required for customer-facing applications like chatbots, fraud detection, and autonomous control systems.

Reinforcement Learning (RL)

A machine learning paradigm where an agent learns by interacting with an environment and receiving reward or penalty signals. RL is the foundation of game-playing systems like AlphaGo and increasingly powers robotics, logistics optimisation, and dynamic pricing.

Reinforcement Learning from Human Feedback (RLHF)

A training technique that refines language model behaviour by learning from human preferences rather than fixed labels. RLHF is a primary method used to align LLMs like ChatGPT and Claude with desired values and reduce harmful outputs.

Residual Connection

A shortcut connection that adds a layer's input directly to its output, allowing gradients to flow more easily during training and enabling very deep networks. Residual connections are essential in transformers and were pioneered in the ResNet image model family.

Retrieval-Augmented Generation (RAG)

A technique that enhances LLM responses by retrieving relevant information from external knowledge sources before generating a response. RAG improves accuracy, reduces hallucinations, and enables LLMs to access up-to-date information without retraining.

Revenue AI

AI applications that directly grow top-line revenue—through personalised recommendations, dynamic pricing, AI-generated leads, and hyper-personalised marketing. Revenue AI initiatives often have the highest strategic impact but require strong data foundations and careful A/B testing to validate causal lift.

Right to Explanation

The GDPR right (Article 22) for individuals to obtain meaningful information about the logic of automated decision-making that significantly affects them, including profiling. This right drives XAI requirements in credit scoring, HR, and other high-stakes AI applications.

Self-Supervised Learning

A training paradigm where a model generates its own supervision signal from unlabelled data—for example, by predicting masked words in a sentence. Self-supervised pre-training on internet-scale text or images is what enables foundation models to acquire broad world knowledge.

Semantic Search

A search approach that retrieves results based on the meaning and intent of a query rather than exact keyword matches. Semantic search is powered by embeddings and vector databases, enabling far more relevant enterprise knowledge retrieval.

Shadow Mode

A deployment technique where a new model processes production traffic in parallel with the existing system but its predictions are logged rather than served to users. Shadow mode enables risk-free validation of model behaviour on real-world data before cutover.

SME AI Activation

My product lifecycle run on compressed, budget-conscious timelines for small and medium enterprises entering AI for the first time. The same path — decide, build to launch, then operate and scale — moves an SME from confusion to a production capability without the upfront investment of a large enterprise programme.

Softmax

A mathematical function that converts a vector of raw logits into a probability distribution summing to 1. Softmax is applied at the output of classifiers and language models to produce token probabilities used in sampling and decoding.

Sparse Model

A model architecture that activates only a subset of its parameters for any given input, rather than the full network. Sparse models—enabled by Mixture of Experts designs—achieve larger total capacity while keeping per-inference compute manageable.

Supervised Learning

A machine learning approach where the model is trained on labelled input-output pairs. The model learns to map inputs to correct outputs, enabling predictions on new, unseen data. Most commercial ML models in production today are supervised.

Technical Documentation (AI Act)

A mandatory artefact under the EU AI Act that high-risk AI providers must prepare and maintain, detailing the system's purpose, architecture, training methodology, validation data, performance metrics, risk management measures, and post-market monitoring plan.

Temperature (LLM)

A sampling parameter that controls the randomness of an LLM's output. A temperature of 0 produces deterministic, focused responses; higher values introduce creative variability. Selecting the right temperature is part of operationalising LLMs in production workflows.

Token Budget

The total number of tokens allocated for a model request, encompassing both input (prompt + context) and output. Managing token budgets is central to controlling inference cost in production LLM applications, especially when processing long documents or maintaining conversational history.

Tokenization

The process of splitting raw text into smaller units called tokens—typically sub-words or word-pieces—that serve as the basic input unit for language models. Token count determines both model context limits and API pricing, making tokenization an important operational consideration.

Top-p Sampling (Nucleus Sampling)

A decoding strategy that restricts the model's next-token choices to the smallest set of tokens whose cumulative probability exceeds a threshold p. Used alongside temperature, top-p sampling balances output diversity and coherence in production LLM deployments.

Training (AI)

The process of exposing a model to large volumes of labelled or unlabelled data and adjusting its internal parameters to minimise prediction errors. Training is computationally intensive, often performed on GPU clusters, and constitutes the major cost in foundation model development.

Transfer Learning

A technique where a model pre-trained on one task or dataset is adapted for a different but related task. Transfer learning dramatically reduces the data and compute needed to build performant models for specialised domains like legal, medical, or industrial applications.

Transformer

The dominant neural network architecture for language, vision, and multimodal AI, introduced in the 2017 "Attention Is All You Need" paper. Transformers use self-attention to process all tokens in parallel, enabling training on internet-scale data and powering every major LLM in use today.

Triton Inference Server

NVIDIA's open-source inference serving software that supports multiple frameworks (TensorRT, ONNX, PyTorch, TensorFlow) on GPU infrastructure. Triton is widely used in enterprise deployments requiring maximum throughput from GPU hardware.

Unacceptable Risk AI

The highest risk tier under the EU AI Act, covering AI applications whose potential harms to society are deemed too severe to permit. Systems in this category are prohibited from being placed on the market or put into service in the EU.

Unsupervised Learning

A machine learning approach that discovers structure in unlabelled data. Common techniques include clustering (grouping similar items) and dimensionality reduction. It is often used for anomaly detection and exploratory data analysis.

Vector Database

A specialised database designed to store and efficiently search high-dimensional embedding vectors using approximate nearest-neighbour algorithms. Vector databases are the infrastructure backbone of RAG systems and semantic search applications.

Vision Transformer (ViT)

An adaptation of the transformer architecture to image data, treating fixed-size image patches as tokens. ViTs now outperform convolutional networks on many computer vision benchmarks and are used in medical imaging, satellite analysis, and industrial quality control.
