model weights
Definition
compound. the numbers inside an AI model that tell it how much importance to give to different pieces of information. You can think of them as the 'memory' or 'knowledge' the computer has learned from its training.
compound. the numerical parameters within a neural network that determine the strength of the connection between nodes. These values are adjusted during the training process to minimize error and represent the learned patterns of the model.
Examples
“The developer downloaded the model weights to run the AI locally.”
“After training the neural network for three days, the researchers saved the model weights to a file for later deployment.”
“Fine-tuning a large language model involves adjusting the pre-trained model weights on a smaller, specialized dataset to improve performance on specific tasks.”
Examples
simple
“The developer downloaded the model weights to run the AI locally.”
contextual
“After training the neural network for three days, the researchers saved the model weights to a file for later deployment.”
complex
“Fine-tuning a large language model involves adjusting the pre-trained model weights on a smaller, specialized dataset to improve performance on specific tasks.”
Usage
usually plural; refers specifically to the learned parameters rather than the architecture of the model.
Teaching tip
useful for ESP (English for Specific Purposes) students in tech; explain that 'weights' here functions as a noun meaning 'importance' or 'value' rather than physical heaviness.
Real-World Examples
“Most companies instead release something called model weights — the numerical parameters learned during an AI’s training period — while keeping other crucial components, including training data, code, model architecture, and configuration methods, private.” “The report emphasized the importance of securing model weights, which are the values within an artificial neural network that are adjusted during training to provide functionality, like ChatGPT's ability to respond to inquiries.” “Yet Moonshot says it plans to release K3’s full model weights by July 27, which would allow other organizations to host and modify the model themselves.” - Exam level
