Deeper Inquiries

Can relying solely on API access for generating DP synthetic texts raise any ethical concerns

Relying solely on API access for generating DP synthetic texts can raise ethical concerns related to data privacy and security. Since the API access involves interacting with powerful language models (LLMs) like GPT-3.5, there is a risk of potential misuse or unauthorized access to sensitive information. The use of such advanced AI technology for generating synthetic data raises questions about consent, transparency, and accountability in handling private data. Additionally, there may be concerns about bias in the generated text or unintended consequences of using AI algorithms without proper oversight.

What are potential drawbacks or limitations of using powerful LLMs like GPT-3.5 with algorithms such as AUG-PE

Using powerful LLMs like GPT-3.5 with algorithms such as AUG-PE also comes with drawbacks and limitations. One limitation is the lack of interpretability in the decision-making process of these models, making it challenging to understand how they generate text outputs and ensuring that they adhere to ethical standards. Another drawback is the computational resources required to run these large models efficiently, which can lead to high costs and environmental impact due to increased energy consumption.
Furthermore, relying on proprietary LLMs like GPT-3.5 may restrict accessibility and transparency since their inner workings are not fully disclosed or open-source for scrutiny by researchers or developers. This lack of transparency could hinder efforts towards building trust in AI systems used for privacy-preserving applications.
Additionally, using powerful LLMs introduces risks associated with overfitting or memorization of training data, potentially leading to privacy breaches if sensitive information from the training dataset leaks into the synthetic texts generated by these models.
