As the field of artificial intelligence (AI) continues to gain popularity and momentum, a critical issue has emerged: the scarcity of training data. Considered the fuel that powers powerful AI systems, the shortage of sufficient data threatens to hinder the growth of AI models, particularly large language models. In fact, it may even alter the trajectory of the AI revolution itself. But why is the potential lack of data a concern, especially when there is an abundance of information readily available on the web? And can this risk be effectively addressed?
To train accurate and high-quality AI algorithms, an extensive amount of data is required. For example, ChatGPT, a popular language model, was trained using a staggering 570 gigabytes of text data, equivalent to approximately 300 billion words. Similarly, the stable diffusion algorithm, responsible for AI image-generating applications like DALL-E, Lensa, and Midjourney, was trained on the LIAON-5B dataset, consisting of 5.8 billion image-text pairs. Inadequate training data can result in the production of inaccurate or low-quality outputs by the algorithm.
Not only is quantity crucial, but the quality of the training data is also of utmost importance. While low-quality data, such as social media posts or blurry photographs, may be easy to acquire, they are insufficient for training high-performing AI models. Social media content, for instance, often contains biases, prejudice, disinformation, or illegal material, which can be replicated by the AI model. Microsoft encountered this issue when training an AI bot using Twitter content, resulting in the production of racist and misogynistic outputs. Consequently, AI developers seek high-quality content from sources like books, online articles, scientific papers, Wikipedia, and specific filtered web content. For instance, the Google Assistant was trained on 11,000 romance novels extracted from Smashwords, a self-publishing site, to enhance its conversational abilities.
Limited Growth Potential: Data Scarcity in AI
Despite AI developers training models on ever-expanding datasets, research indicates that online data resources are not growing at the same pace. A recent paper predicted that if current AI training trends persist, the availability of high-quality text data could be depleted before 2026. Additionally, it estimated that the exhaustion of low-quality language data could occur between 2030 and 2050, while low-quality image data may be depleted by 2030 and 2060. These projections raise concerns about the development and progress of AI, given its potential to contribute trillions to the world economy by 2030, according to PwC (accounting and consulting group).
While the scarcity of data may be disconcerting, there are potential solutions and opportunities to mitigate the risks associated with data shortages. AI developers can focus on improving algorithms to enhance their efficiency in utilizing existing data. In the coming years, it is conceivable that AI systems will be trained using reduced data volumes, paired with potentially lesser computational power requirements. This advancement would not only address the data shortage issue but also contribute to reducing AI’s carbon footprint, promoting more sustainable AI development.
Another approach involves the use of AI itself to generate synthetic data for training purposes. In other words, AI developers can create the required data specifically tailored to their AI models. Several projects are already utilizing synthetic content sourced from data-generating services like Mostly AI, further indicating the potential prevalence of this approach in the future.
Furthermore, content creators are taking a stand against the unauthorized use of their content to train AI models. Companies such as Microsoft, OpenAI, and Stability AI have faced legal actions from creatives seeking remuneration for their work. News Corp, a major news content owner, has even initiated negotiations with AI developers to establish content deals that would require payment for training data. The inclusion of compensation for content creators could help rebalance the power dynamic between creatives and AI companies.
As the AI industry continues to advance, the scarcity of training data emerges as a significant challenge. The quality and quantity of data play a critical role in training accurate and high-quality AI models. However, the growth of AI models may be impeded if the current trend of data shortages prevails. Nonetheless, the development of more efficient algorithms and the utilization of synthetic data offer promising solutions to address this issue. Moreover, ensuring content creators are fairly compensated for their work could contribute to a more equitable relationship between creatives and AI companies. Ultimately, the future of AI hinges on effectively confronting the challenge of data scarcity and unlocking its full potential for the benefit of society.
