Generative AI - Navigating in Research
Published on December 18, 2023

Generative artificial intelligence (AI) refers to advanced systems that automatically generate new content like text, images, or code based on patterns learned from data. The recently launched ChatGPT is an example of a text-generative AI tool. While a universal enthusiasm surrounds these systems, researchers are still determining how generative AI may pragmatically assist research workflows if used appropriately. This article provides a simple overview of the key characteristics and potential applications to illustrate the wide applicability of generative AI in research.

 

What is Generative AI?

Generative AI systems use neural networks trained on massive datasets to generate new outputs. For instance, text-generative AI like ChatGPT ingests vast amounts of text data to learn linguistic patterns. When given a text prompt, it predicts probable word sequences and generates original content by forming coherent continuations.

Though the outputs seem highly realistic, the systems do not comprehend a language or facts. They just repeat learned patterns without real-world understanding. So, their responses could be flawed despite intensive training in neural networks, which makes critical evaluation essential before widespread research application (Chakya, 2023). 

 

Examples of Generative AI

Text Generative AI, exemplified by systems like ChatGPT, harnesses learned probability patterns to auto-generate text continuations in response to prompts. While proficient in crafting lengthy, human-like responses across diverse topics, it is not immune to occasional inaccuracies. Its strength lies in swiftly generating drafts, outlines, ideas, or initial passages, serving as a valuable tool for writers seeking a starting point that requires subsequent refinement.

Image Generative AI, exemplified by DALL-E 2 and Midjourney, breathes life into textual descriptions by conjuring novel images through learned visual patterns. However, its creativity is confined by training data biases, resulting in imagery occasionally lacking genuine innovation or profound meaning. 

While this technology holds promise for illustrating concepts and crafting representations, it underscores the irreplaceable role of human artistry in infusing depth and significance into visual creations.

Code Generative AI, exemplified by tools like GitHub Copilot, autonomously crafts code in languages like Python by leveraging learned code patterns. While the generated code is functional, it may exhibit inefficiencies or unconventional practices, posing challenges for practices such as modular programming. This technology proves invaluable for creating boilerplate segments and rapid prototypes, yet it requires scrutiny and critical review before deployment to ensure robust, repeatable, and efficient production-ready solutions.

 

Potential Research Applications 

When used prudently, generative AI may assist researchers in certain ways:

a.   Literature discovery - Rapidly analyze and summarize large sets of academic papers by identifying connections between prior works. Useful as a starting point to understand the broader literature landscape.

b.  Study design - Propose draft study designs, methodologies, and analysis plans when given high-level research goals. Provides ideas to refine.

c.   Data exploration - Visually explore datasets by generating charts, graphs, and other visualizations. This may surface interesting trends and relationships.

d.  Writing assistance - Generate sections of text for papers based on outlines and prompts. It is useful for creating rough drafts, which require extensive human editing.

e.   Programming - Generate code segments for prototypes or boilerplate functionality. Reviewing and debugging by programmers is necessary before use.

Generative AI has a wide range of potential applications in diverse fields, such as finance, supply chain management, voting, healthcare, engineering, law, and journalism. In each case, the keys are applying generative AI thoughtfully to produce high-quality content representative of training data from the specific domain and maintaining rigorous human oversight to critically evaluate outputs and avoid discrepancies. While generative AI may augment certain tasks, its appropriate usage requires utmost care and domain expertise (Murphy Kelly, 2023).

 

Risks and Limitations in Generative AI

Despite the potential, caution is necessary before applying, as generative AI has the following fundamental limitations:

·         Factual inaccuracies and logical errors are common. Lacks real-world understanding.

·         Tendency for bias, stereotypes, and repetition due to the quality of training data and lack of comprehension.

·         Legal concerns around copyright, data rights, and plagiarism require strict oversight.

·         Cannot replicate true human creativity, critical thinking, and problem-solving skills.

·         Overdependence can inhibit learning and research skills like analysis, writing, and programming.

  • Relies on human feedback for validation and refinement
  • Produced artificial hallucinations in the absence of human feedback

 

Artificial Hallucinations & Human Expertise

In the context of generative AI, artificial hallucinations are instances whereby artificial intelligence (AI) systems—typically deep learning models—produce results that are absurd, unimportant, or misrepresent reality. These anomalies are usually caused by algorithm biases or training data limitations, which cause the model to produce outputs that greatly differ from accurate or expected representations. Human expertise is essential to reducing these hallucinations. AI and application domain experts can employ various tactics to preserve the accuracy and dependability of AI results.

Firstly, biases or errors in the model's learning process can be found and corrected through rigorous validation and testing against a variety of scenarios. Secondly, by making sure the model's training is more in line with actual events, ongoing monitoring and updating of the AI models with fresh, accurate, and varied data can lessen the possibility of hallucinations and the intensity of misrepresentations or biases. Thirdly, a crucial layer of oversight is ensured by putting in place human-in-the-loop systems, wherein human judgment is used to supervise, edit, or reject AI-generated outputs. Working together, AI systems and human experts improve output accuracy and dependability while also fostering the development of increasingly reliable and strong AI systems that are consistent with human values and comprehension.

It is pivotal to recognize that generative AI is an assistive tool under human direction and not an independent expert. Generative AI may augment selected research tasks with considerate usage and critical oversight. However, human intelligence remains invaluable for meaningful research advances (Anders, 2023).
