The Shift from Big Data to Good Data

In recent years, there has been a shift in the approach to artificial intelligence (AI) development, specifically in the realm of data-centric AI. Traditionally, AI development has been focused on the model-centric approach, which involved writing code to implement algorithms or models and then training them on data. However, this paradigm has limitations, particularly when it comes to practical applications.

The Conventional Paradigm of Model-Centric AI Development

Under the model-centric approach, developers would download data and hold it as fixed, while iterating on the code or the model itself. This approach led to advancements in neural networks, decision trees, and other architectures. However, as AI expanded beyond consumer software and internet companies, its impact on other industries remained limited.

The Need for Data-Centric AI

To unlock AI's full potential and democratize access to it, a shift towards data-centric AI is necessary. Data-centric AI involves systematically entering the data used to build an AI system. This approach has proven to drive faster progress in practical applications by focusing more attention on entering high-quality data.

The Two Biggest Barriers to AI Adoption in Other Industries

While AI has transformed consumer software and internet companies, its adoption in other industries remains limited. Two major barriers are preventing widespread adoption:

Barrier 1: Small Data Sets

A significant challenge lies in working with small data sets. For example, in computer vision applications such as defect detection in manufacturing, the number of images available for training can be as low as 50 or even fewer. The conventional methods used to train models on massive data sets do not work efficiently with small data sets. To make AI successful in these domains, developers must find ways to work with smaller data sets effectively.

Barrier 2: The Customization Problem or the Long Tail of AI Projects

Another barrier to AI adoption is the customization problem, particularly in industries outside consumer software and the internet. These industries have numerous valuable projects, each worth one to five million dollars. However, creating custom AI systems for each of these projects would require a significant number of machine learning engineers, which is impractical and expensive. To overcome this challenge, the industry needs vertical platforms that empower end customers to build their own custom AI systems without the need for extensive expertise.

Building Vertical Platforms for Democratizing Access to AI

To democratize access to AI and make it more accessible to a broader audience, the industry needs to develop vertical platforms. These platforms enable end customers, such as IT personnel in manufacturing plants, to build and train their own custom AI models. By providing tools and empowering people to enter and engineer the data according to their domain knowledge, these platforms alleviate the need for extensive customization and make AI systems more accessible.

The Role of Data Engineering in AI Development

Data engineering plays a crucial role in the iterative process of AI development. Rather than considering data cleaning as a one-time preprocessing step, it should be viewed as an integral part of the development workflow. Data cleaning and improvements should be approached iteratively, allowing developers to continually enhance the quality and effectiveness of their data. This approach not only leads to better results but also drives developer productivity.

Improving Data Quality in the Iterative Process

Consistency and accuracy in data labeling are essential for training effective machine learning models. Inconsistent labels and discrepancies in labeling instructions can lead to confusion and hinder model performance. To address this, tools like team-editable defect books and agreement-based labeling can enable teams to collaborate and define clear labeling instructions, improving the consistency and accuracy of the data.

The Need for Rapid Innovation in Data-Centric AI

Data-centric AI development emphasizes the importance of iteration and rapid innovation. Unlike the traditional model-centric approach, where a lot of time is spent on tuning models and hyperparameters, data-centric AI allows developers to focus on improving the data itself. This iterative process enables quick adjustments and improvements, leading to faster progress in developing AI systems.

In conclusion, the shift towards data-centric AI development is crucial for unlocking AI's full potential and democratizing access to it. By addressing the barriers of small data sets and customization, and by developing vertical platforms and improving data quality, the industry can empower more people to build AI systems and drive innovation in various domains.
