// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM
Residual Connection
This is a shortcut in a neural network that allows information to bypass one or more layers and be added directly to the output of a later layer, helping to train very deep networks.
TECHNICAL DEFINITION
A skip connection in deep neural networks, particularly prominent in ResNet architectures, where the input from a previous layer is added directly to the output of a subsequent layer, facilitating gradient flow, mitigating the vanishing gradient problem, and enabling the training of much deeper models.
BACKGROUND
Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd., doing business as DeepSeek, is a Chinese artificial intelligence (AI) company that develops large language models (LLMs). Based in Hangzhou, Zhejiang, DeepSeek is owned and funded by High-Flyer, a Chinese hedge fund. DeepSeek was founded in July 2023 by Liang Wenfeng, who serves as the CEO for both of the companies. The company launched an eponymous chatbot alongside its DeepSeek-R1 model in January 2025.
