Term Quantization
Quantization is a representative lightweight technique that reduces the size and amount of calculations by lowering the numerical precision of the model.
Term RAG retrieval augmented generation
RAG is a technique that retrieves relevant documents before generating an answer, helping reduce hallucinations.
Term Red Team red teaming
Red Team is a verification activity that detects risks in advance by deliberately attacking AI’s loopholes.
Term Reinforcement learning RL
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.
Term RLHF Human Feedback Reinforcement Learning
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.
Term RPA robotic process automation
RPA is a technology in which software robots replace repetitive computer tasks (input, copy, transfer) previously performed by humans.
Term Scaling law
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.
Term Singularity
This refers to the hypothetical point when AI surpasses human intelligence and humans cannot control the speed of its development.
Term Sort alignment
Sort is a field of research that makes AI behave in line with human intentions and values. This is a core concept in AI safety discussions.
Term Sovereign AI national AI
This refers to national-level AI created with domestic data and language rather than relying on foreign technology. These are Korea’s domestic AI policy keywords.
Term Stargate
Stargate is a large-scale AI data center construction project promoted by OpenAI, Softbank, and Oracle. It symbolizes the AI infrastructure competition worth hundreds of billions of dollars.
Term STT speech recognition, speech to text
STT is the art of transcribing words into writing. It is used to automatically create meeting minutes and create subtitles.
Term Supervised learning
Supervised learning is a learning method that teaches AI using data with correct answers. This is done by labeling the photo “cat” and training it.
Term Synthetic data
The data generated by AI is used again for AI learning. It is an alternative to the depletion of real data and a subject of debate over quality degradation.
Term System prompt
System prompt refers to basic instructions given to AI before starting a conversation. AI’s tone and rules are set here.
Term Token
A token is the smallest text unit an AI model processes, and it is commonly used to calculate usage limits and costs.
Term TPU tensor processing unit
TPU is an AI-specific chip designed by Google itself. It is attracting attention as a rival to NVIDIA GPUs.
Term Transformer
Transformer is an AI structure announced by Google in 2017, and is the foundation technology for most modern generative AI, including ChatGPT.
Term TTS speech synthesis, text to speech
TTS is a technology that reads text in a natural voice. It is the foundation of AI dubbing and audiobooks.
Term Turing Test
If you cannot tell whether the person you are talking to is an AI or a human, it is a classic criterion to assume that you are intelligent.
