Model Cards – What the big players use to help govern their AI efforts

Machine learning model cards are a tool designed to provide information and context about machine learning models, particularly in the context of their deployment and use. Model cards aim to enhance transparency, accountability, and trust in machine learning systems. They are akin to “nutrition labels” for machine learning models, offering insights into various aspects of a model’s behavior and performance. Model cards are typically created and provided by the developers or organizations responsible for a particular machine learning model.

All major AI companies utilize model cards:

Here are some key components and information typically found in machine learning model cards:

1. Model Overview: This section provides a high-level summary of the model, including its name, version, and a brief description of its purpose and intended use.

2. Model Performance: Information about the model’s performance, including metrics such as accuracy, precision, recall, F1 score, and any other relevant evaluation criteria. It may also include performance across different datasets or domains.

3. Training Data: Details about the data used to train the model, including the source of the data, size of the dataset, and any preprocessing steps applied.

4. Model Architecture: Information about the model’s architecture, including the type of model (e.g., neural network, decision tree), the number of layers, and the types of layers used.

5. Hyperparameters: Key hyperparameters used during training, such as learning rate, batch size, and regularization methods.

6. Data and Evaluation Metrics: Information about bias and fairness considerations in the training data and model performance, including any efforts made to mitigate biases and potential fairness issues.

7. Intended Use Cases: A description of the intended use cases for the model, as well as any known limitations or constraints.

8. Ethical Considerations: Information about ethical considerations related to the model, including guidelines for responsible use and potential risks.

9. Deployment Information: Details about how the model can be deployed in various environments, including any necessary software dependencies and hardware requirements.

10. References: Citations or links to relevant research papers, documentation, and other resources for further information.

Model cards are part of a broader effort to promote transparency and accountability in the field of machine learning, particularly in applications where the decisions made by AI systems can have significant real-world impact. They help users and stakeholders better understand what a model can and cannot do and make informed decisions about its deployment and use. Model cards are often used alongside other documentation and tools to support responsible AI development and deployment.
