Frequently Asked Questions (FAQs)

What is the full form of LLM and GPT in AI?

LLM stands for Large Language Model. GPT stands for Generative Pre-trained Transformer. It is an autoregressive deep learning model architecture that uses attention mechanisms to generate natural human-like text.

What is the full form of RAG and RLHF?

RAG stands for Retrieval-Augmented Generation (retrieving relevant facts from external vector knowledge bases to enhance LLM responses). RLHF stands for Reinforcement Learning from Human Feedback (fine-tuning models based on human ranking of responses).

What is the difference between AGI, ANI, and ASI?

ANI stands for Artificial Narrow Intelligence (specialized in one task, like chess or translation). AGI stands for Artificial General Intelligence (human-level comprehension across diverse domains). ASI stands for Artificial Superintelligence (surpassing human cognitive abilities).

What is the full form of CNN and RNN in deep learning?

CNN stands for Convolutional Neural Network (primarily used for computer vision and image processing). RNN stands for Recurrent Neural Network (designed for sequential and time-series data like text and audio).

What are TPU and NPU in AI hardware?

TPU stands for Tensor Processing Unit (custom AI accelerator ASIC developed by Google for matrix operations). NPU stands for Neural Processing Unit (hardware processor optimized for deep learning neural network acceleration in mobile and edge devices).
