Artificial Intelligence
Here’s your, A–Z words of AI with simple one-line explanations
A – Agent: AI that can think and act on its own to complete tasks.
B – Bias: When AI gives unfair or incorrect results due to bad data.
C – Context Window: The amount of text AI can remember at one time.
D – Diffusion: A method AI uses to create images from noise step by step.
E – Embedding: Turning text into numbers so AI can understand meaning.
F – Fine-tuning: Improving an AI model by training it on specific data.
G – GPT: A powerful AI model that generates human-like text.
H – Hallucination: When AI makes up information that is not true.
I – Inference: Using a trained AI model to get answers or predictions.
J – Jailbreak: Trying to trick AI into ignoring its safety rules.
K – Knowledge Base: A collection of information AI uses to answer questions.
L – LLM: A large AI model trained to understand and generate language.
M – Multimodal: AI that can understand text, images, audio, and more.
N – Neural Net: A system designed like the human brain to process data.
O – Open Source: AI models that are free for anyone to use and modify.
P – Prompt: The instruction or question you give to AI.
Q – Quantization: Making AI models smaller and faster by reducing precision.
R – RAG: AI that uses external data to give more accurate answers.
S – Supervised Learning: Training AI using data with correct answers.
T – Tokens: Small pieces of text that AI reads and processes.
U – Unsupervised: AI learning patterns without labeled examples.
V – Vector DB: A database that stores data in a way AI can search meaningfully.
W – Weights: Values inside AI that help it make decisions.
X – XGBoost: A fast algorithm that improves predictions using many small models.
Y – YOLO: A real-time system that detects objects in images or videos.
Z – Zero-shot: When AI solves a task without being trained on it before.
