Prompt Injection is an attack technique that manipulates AI using instructions secretly planted in documents or web pages. It is a representative security threat in the AI agent era.

Quant refers to investment strategies or systems that trade mechanically by analyzing market data with mathematical and statistical models.

Quantization is a representative lightweight technique that reduces the size and amount of calculations by lowering the numerical precision of the model.

RAG is a technique that retrieves relevant documents before generating an answer, helping reduce hallucinations.

Red Team is a verification activity that detects risks in advance by deliberately attacking AI’s loopholes.

Reinforcement learning is a learning method that allows you to learn through trial and error by giving rewards if you do well and penalties if you do not. This is the core technique of AlphaGo and its inference model.

RLHF is a training technique in which humans score AI answers and refine them to provide more useful and safer answers. It is considered a key technology that made ChatGPT usable.

RPA is a technology in which software robots replace repetitive computer tasks (input, copy, transfer) previously performed by humans.

The rule of thumb is that as the amount of model, data, and calculation increases, performance predictably improves. This is the theoretical basis for AI investment competition.

SEO means improving titles, descriptions, structure, and content so search engines can understand and show a page properly.

This refers to the hypothetical point when AI surpasses human intelligence and humans cannot control the speed of its development.
