Embeddings

Embeddings are numerical vector representations of text that capture semantic meaning, enabling AI systems to measure similarity between concepts.

F

Few-Shot Learning

A technique where a model adapts to a new task using only 2 to 20 labeled examples provided directly in the prompt, without updating model weights.

Fine-Tuning

Fine-tuning is the process of training a pre-trained AI model on specialized data to improve its performance on specific tasks or domains.

Function Calling

Function calling is the ability of AI models to invoke external functions or APIs by generating structured outputs that match predefined schemas.

Foundation Model

A foundation model is a large, pre-trained AI model that serves as a versatile base, adaptable to a wide range of downstream tasks through fine-tuning or prompting.

G

Generative AI

Generative AI refers to AI systems that create new content — text, images, code, music, or video — based on learned patterns from training data.

H

Hallucination

AI hallucination is when an AI model generates plausible-sounding but factually incorrect information with unwarranted confidence.

Human-in-the-Loop (HITL)

Human-in-the-loop (HITL) is a design pattern where human judgment is integrated into AI workflows at critical decision points for quality control and oversight.

I

Inference

Inference is the process of running a trained AI model to generate predictions or outputs from new inputs.

L

Large Language Model (LLM)

A large language model (LLM) is a neural network trained on massive text data that can understand and generate human-like language, code, and reasoning.

M

Mixture of Experts (MoE)

Mixture of Experts (MoE) is a neural network architecture where multiple specialized sub-networks ('experts') process different inputs, with a learned gating mechanism routing each token to only the most relevant experts. This allows massive parameter counts without proportional inference cost.

Model Distillation

Model distillation is a technique where a smaller "student" model is trained to replicate the behavior of a larger "teacher" model, preserving most of the capability at a fraction of the computational cost.

Multi-Agent System

A multi-agent system is an architecture where multiple AI agents collaborate, each with specialized roles, to accomplish complex tasks that no single agent could handle alone.

Microservices is an architectural pattern where an application is built as a collection of small, independent services that communicate over well-defined APIs.

N

Neural Network

A neural network is a computing system inspired by the human brain, composed of interconnected layers of nodes that learn patterns from data.

Natural Language Processing (NLP)

Natural language processing (NLP) is the branch of AI focused on enabling machines to understand, interpret, and generate human language in meaningful ways.

O

R

RLHF (Reinforcement Learning from Human Feedback)

RLHF (Reinforcement Learning from Human Feedback) is a training technique that uses human preference ratings to fine-tune language models, steering their outputs toward responses that are more helpful, harmless, and honest.
