Model Delphi makes moral judgments based on common sense ethical data: Researchers developed Delphi AI model to make moral judgments based on ethical dilemmas, achieving high accuracy, but internet-trained GPT-3 performed poorly, suggesting ethical context is less prevalent online.
Researchers at the Allen Institute for AI have developed a model named Delphi, which makes moral judgment calls based on a large dataset of common sense ethical judgments. This includes examples from various everyday situations, some of which can be quite extreme, like saving a child by killing a bear or exploding a nuclear bomb. Delphi achieved high accuracy compared to other models, reaching 92.1%, as evaluated by crowd workers on Mechanical Turk. However, it's worth noting that GPT-3, which was trained on a massive amount of internet data, performed much lower in this ethical judgment task. This might suggest that the context of ethics is less prevalent or less explicitly presented on the internet compared to other types of content. Overall, this research demonstrates the potential for AI to make moral judgments based on human ethical norms, but also highlights the importance of understanding the limitations and potential biases of such models.
Understanding AI language model performance: Specific models outperform GPT 3 in certain areas, but GPT 3 can still be effective. Performance depends on task, data, and model design. Challenges include understanding why some topics are harder for models to grasp, and addressing ethical implications and potential biases.
The performance of AI language models like GPT 3 can vary greatly depending on the specific task and the data they are trained on. During a discussion, it was noted that a model specifically trained for a task, like the Delphi model, outperformed GPT 3 in certain areas, such as common sense reasoning and understanding context. However, GPT 3, being a general-purpose model, can still be effective in many scenarios with the right prompts and examples. The discussion also touched on the challenges of understanding why some topics might be easier or harder for AI models to grasp. Researchers are still exploring this area, as the inner workings of these models are not always clear. One factor that can influence a model's performance is the availability and quality of data related to the topic. Adversarial examples, where the model is presented with deliberately misleading information, can also reveal unexpected behaviors. As AI models continue to evolve, it will be essential to consider their ethical implications and potential biases. Some researchers are even exploring the idea of AI models creating their own ethics principles. Overall, the conversation highlighted the importance of ongoing research and development in the field of AI language models and the need to address the complexities and nuances of human language and common sense reasoning.
