The Data Dilemma: How AI Could Run Out of Fuel by 2026

 


Artificial intelligence (AI) is transforming many fields of science and engineering, from natural language processing to computer vision. However, one of the main challenges in developing AI models is finding enough data to train them. Data is the fuel that powers AI, and the more data a model has, the better it can learn and perform. But is bigger always better when it comes to data?

A recent study from the University of Toronto Engineering researchers, published in Nature Communications1, suggests that this may not be the case. The study focused on materials science, a domain where finding new materials with desirable properties is a key goal. The researchers used deep learning, a type of AI that can learn from complex and high-dimensional data, to predict various properties of materials, such as their stability, band gap, and formation energy.

The researchers found that the performance of their deep learning models depended not only on the size of the data, but also on its quality and diversity. They showed that by selecting subsets of data that were more representative and informative, they could achieve similar or even better results than using the entire dataset. In other words, they could do more with less.

The study also revealed some interesting insights into how deep learning models learn from data. The researchers used a technique called influence function analysis to identify which data points had the most impact on the model’s predictions. They found that some data points were more influential than others, and that these influential points tended to be outliers or boundary cases that were different from the majority of the data. These points provided valuable information that helped the model generalize better to new and unseen data.

The study has implications for both AI and materials science. For AI, it suggests that bigger datasets might not always be better, and that carefully selecting and curating data can improve the efficiency and accuracy of deep learning models. For materials science, it demonstrates that deep learning can be a powerful tool for discovering new materials and understanding their properties, especially when combined with domain knowledge and human expertise.

The study also opens up new questions and directions for future research. For example, how can we automatically identify and select high-quality subsets of data? How can we measure and improve the diversity and representativeness of data? How can we design deep learning models that can learn from small and noisy data? How can we leverage deep learning to accelerate the discovery and design of novel materials for various applications?

These are some of the challenges and opportunities that lie ahead for AI and materials science, and the researchers hope that their study will inspire more collaboration and innovation in these fields.

Artificial intelligence (AI) is one of the most rapidly advancing fields of technology, with applications ranging from health care to entertainment. However, behind every AI system, there is a massive amount of data that is used to train it and make it smarter. Data is the vital force of large AI models, and thus of the industry itself. But it’s also a finite resource — and companies could run out1.

Why data matters for AI

AI systems rely on data to learn from examples and patterns, and to improve their performance and accuracy over time. The more data a model has, the better it can capture the complexity and diversity of the real world. For instance, a natural language processing (NLP) model that can understand and generate text needs to be trained on a large corpus of text data, such as books, articles, social media posts, and so on. Similarly, a computer vision model that can recognize and manipulate images needs to be trained on a large collection of image data, such as photographs, drawings, paintings, and so on.

However, not all data are created equal. AI models need high-quality data that are relevant, accurate, diverse, and representative of the problem they are trying to solve. Low-quality data, such as noisy, incomplete, outdated, biased, or illegal data, can lead to poor or even harmful outcomes. For example, a facial recognition system that is trained on a dataset that is mostly composed of white male faces will likely perform poorly or unfairly on faces of other genders, races, or ethnicities.

The challenge of finding enough data

The AI industry has been growing exponentially in recent years, fueled by the demand for more powerful and sophisticated AI models. These models require larger and larger datasets to train on, which are becoming harder and harder to find. According to a recent study2, the AI industry might run out of high-quality text data by 2026, and low-quality text data by 2050, if the current trends continue. The same study also estimated that the AI industry might run out of low-quality image data by 2060.

The main reason for this potential shortage is that the growth of online data, such as web pages, social media posts, and online articles, is slowing down compared to the growth of AI datasets. Moreover, most of the online data are not suitable for AI training, as they are either low-quality, protected by intellectual property rights, or subject to privacy and ethical regulations. Therefore, AI companies have to either create their own data, which is costly and time-consuming, or rely on existing public datasets, which are often limited and overused.

The implications and solutions for the AI industry

Running out of data could have serious consequences for the AI industry, as it could hamper the development and innovation of new AI models and applications. It could also affect the quality and reliability of existing AI systems, as they might become outdated or inaccurate over time. Furthermore, it could create a competitive advantage for those who have access to large and exclusive datasets, and a disadvantage for those who don’t.

However, there are also some possible solutions and alternatives to address this challenge. For example, AI companies could use synthetic data, which are artificially generated data that mimic the characteristics and distribution of real data. Synthetic data can be created using various techniques, such as data augmentation, generative adversarial networks (GANs), or simulation. Synthetic data can help increase the quantity and diversity of data, as well as overcome some of the legal and ethical issues of using real data.

Another possible solution is to use transfer learning, which is a technique that allows an AI model to leverage the knowledge and skills learned from one domain or task to another domain or task. Transfer learning can help reduce the amount of data needed to train a new model, as well as improve its performance and generalization. For example, a NLP model that is pre-trained on a large and general text dataset, such as Wikipedia, can be fine-tuned on a smaller and specific text dataset, such as movie reviews, to perform a sentiment analysis task.

A third possible solution is to use federated learning, which is a technique that allows multiple AI models to learn collaboratively from decentralized and distributed data sources, without sharing or transferring the data itself. Federated learning can help preserve the privacy and security of data, as well as enable the use of data that are otherwise inaccessible or unavailable. For example, a medical image analysis system that is trained on data from multiple hospitals, without exposing the patients’ personal information.

These are some of the ways that the AI industry can cope with the potential data shortage, and continue to develop and improve its models and applications. However, these solutions also come with their own challenges and limitations, such as technical complexity, computational cost, data quality, and ethical implications. Therefore, the AI industry needs to be aware of the risks and opportunities of data, and to adopt responsible and sustainable practices for data collection, generation, and use.

Artificial intelligence (AI) is one of the most promising and disruptive technologies of our time, with applications in various domains such as health, education, entertainment, and security. However, behind every AI system, there is a huge amount of data that is used to train it and make it smarter. Data is the essential ingredient that enables AI to learn from examples and patterns, and to improve its performance and accuracy over time. But what if we run out of data to train AI? Is this a realistic scenario, and what would be the consequences and solutions?

Why data matters for AI

AI systems rely on data to learn from experience and to adapt to new situations. The more data a system has, the better it can capture the complexity and diversity of the real world.
