What Challenges Does Generative AI Face and How to Address Them

Generative AI faces several challenges that hinder its widespread adoption and effectiveness. One major challenge is the lack of control over the generated content, which can lead to unexpected and often undesirable outcomes.

The issue of data quality and availability is a significant one, as generative AI models require large amounts of high-quality data to learn from. If the data is biased, incomplete, or inaccurate, the generated content will likely reflect these flaws.

Another challenge is the difficulty in evaluating the quality and reliability of generative AI outputs. This is particularly true for tasks that require human judgment, such as content creation or decision-making.

Generative AI models can also be vulnerable to adversarial attacks, which are designed to manipulate the model into producing incorrect or misleading results. This is a concern in applications where the stakes are high, such as in healthcare or finance.

Model limitations and risks are a significant concern when it comes to generative AI. Generative AI models face several limitations, including bias, AI hallucination, bugs, and security issues. These limitations can lead to inaccurate or misleading information being generated.

Take a look at this: Limitations of Generative Ai

Bias is a major issue, with 57.5% of papers reviewed highlighting bias as a concern for medical practitioners or patients using AI assistance for medical decisions. Debiasing techniques can be employed, but their efficacy is still a subject of debate. Some debiasing methods might correct for one form of bias but introduce another.

AI hallucination is another significant limitation, where AI models generate wrong information with no credible sources. This can be a serious issue in cases where users rely on AI chatbots for solid information. A complex combination of factors can cause hallucinations, making it challenging to identify the root causes.

These limitations can have real-life consequences, such as when AI chatbots generate misinformation or when users rely on AI for medical advice without proper oversight.

Here are some of the main limitations of generative AI models:

These limitations highlight the need for careful consideration and evaluation of generative AI models before implementing them in medical settings.

Generative AI models face several limitations that users and developers should consider. These limitations include bias, AI hallucination, bugs, and security issues.

Bias is a significant concern in generative AI models, with 58% of papers addressing this issue in a recent review. This bias can manifest in various ways, such as perpetuating stereotypes or discriminating against certain groups.

AI hallucination is another common limitation, where AI models generate information that is not based on credible sources. This can be a serious issue, especially when users rely on AI chatbots for solid information. In fact, 64% of papers in the review mentioned model hallucinations as a major concern.

Bugs and errors can also occur in generative AI models, as seen in the case of ChatGPT, where a user reported a bizarre phenomenon of the chatbot producing garbled sentences. This incident was due to an error in the way the base model assigned context tokens.

Security is another critical limitation of generative AI models, as they can be vulnerable to attacks and misuses. For example, a user was able to trick Chevrolet's GPT-powered chatbot into making a "legally binding offer" for a 2024 Chevy Tahoe at $1.

In many cases, generative AI limitations like hallucinations are caused by a complex combination of factors, making it challenging to identify and address the root causes. However, some recommended solutions include external review by experts and modifying model parameters to mitigate hallucinations.

Here are some common limitations of generative AI models:

It's essential to be aware of these limitations and take steps to mitigate them, especially when using generative AI models for critical tasks or applications.

Generative AI models like ChatGPT can misunderstand prompts, especially in medical settings where patients may be substituting necessary medical advice with chatbot responses.

Crafting effective prompts is crucial, but there's a lack of knowledge on how to do it, even at basic and advanced levels. Most current resources are commercial guides focused on specific products, which may not address the unique requirements of prompting for medical practice.

Some generative AI models can be vulnerable to specific character sequences that can induce harmful, biased, or unintended content in response to user prompts, known as adversarial attacks or jailbreaking.

Only 3 out of 120 papers reviewed mentioned jailbreaking as a concern for generative AI technologies in medical settings, highlighting the need for awareness about this threat.

LLMs can be used to jailbreak other LLMs, and retraining models to patch vulnerabilities is often nonfeasible due to their large size.

Generative AI models can unintentionally carry over biases present in the data they are trained on, leading to harmful outputs and ethical problems.

Geoffrey Hinton warned that AI systems can be incredibly good at something, but biased in ways that are difficult to understand or control. This can have serious consequences, especially in sensitive areas like healthcare or education.

Bias in generative AI models can cause imbalance and partiality in the model's outputs, and can even amplify existing biases in data used for training. For example, AI image generator Midjourney contains bias when it comes to colors, tending to overuse teal and orange.

A unique perspective: Generative Ai Bias

Here are some common biases found in generative AI models:

To mitigate these biases, it's essential to keep a close eye on our models, set rules for how to use AI, and work with diverse leaders and subject matter experts to identify unconscious bias in data and models.

Generative AI models can compromise data privacy, particularly when they contain billions of parameters that require significant computational power to generate accurate responses.

Resource-limited labs or healthcare providers may rely on external, third-party digital tools for computational support, but this raises ethical, regulatory, and patient privacy concerns.

Using third-party generative AI tools can be problematic because sensitive data may be uploaded into these tools without proper review, which is a resource-intensive process.

Institutions face trade-offs between using third-party tools, which are easy to deploy but may raise privacy concerns, and local hosting of AI models, which requires dedicated infrastructure and security measures.

Suggestion: What Are Generative Ai Tools

Local hosting of AI models can lessen privacy risks because data never leave the secure local network or device, but there are still many other concerns.

Developers are creating "lighter" architectures that have fewer than 10 million parameters and can run on local networks or mobile devices, using a combination of model compression and higher-quality training data.

Federated learning is an approach that maintains data privacy by exchanging model updates without sharing patient data, but further work is needed to develop federated learning methods for generative AI technologies in clinical practice.

Generative AI large language models can embed personally identifiable information, making it difficult for consumers to locate and request removal of the information.

To mitigate biases, it's essential to work with diverse leaders and subject matter experts to identify unconscious bias in data and models. This helps ensure that AI systems are fair and unbiased.

Generative AI models can also amplify existing biases, making it crucial to have a diverse team to help identify and address these issues.

A notable example of bias in AI is the Midjourney image generator, which tends to overuse teal and orange colors in its outputs. This is due to an imbalance in the training data.

To alleviate these limitations, it's essential to reduce the imbalance present in the data. This can be achieved by preprocessing the training data to remove bigoted content or altering the algorithm to incorporate human feedback.

However, debiasing techniques can sometimes introduce new biases, making it a complex issue to address. For instance, a reweighting scheme might correct for one form of bias but degrade model performance for another group.

Here are some common biases found in generative AI models:

Generative AI systems often group facts together probabilistically, but they don't always reveal these details when used in applications like ChatGPT.

This lack of transparency raises questions about data trustworthiness. Many generative AI systems search for correlations, not causality, which can lead to unreliable results.

Analysts expect to arrive at a causal explanation for outcomes, but machine learning models and generative AI don't provide this level of insight. This is where model interpretability comes in – understanding why the model gave a particular answer.

Until generative AI systems can provide trustworthy results, they should not be relied upon to make decisions that significantly affect lives and livelihoods.
