// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM

U-Net

U-Net is a type of neural network often used for image segmentation, where it tries to outline specific objects within an image.

TECHNICAL DEFINITION

U-Net is a convolutional neural network architecture characterized by its U-shaped encoder-decoder structure with skip connections between corresponding layers, primarily designed for biomedical image segmentation tasks.

BACKGROUND

A large language model (LLM) is a neural network trained on a vast amount of text for natural language processing tasks, especially language generation. LLMs can typically generate, summarize, translate, and analyze text in many contexts, and are a foundational technology behind modern chatbots. Biased or inaccurate training data can make an LLM's output less reliable.
