What is Data-centric AI?

Data-centric AI is an emerging field that focuses on engineering data to improve AI systems with enhanced data quality and quantity.

Data-centric AI vs. Model-centric AI

<img width="500" src="./imgs/data-centric.png" alt="data-centric" />

In the conventional model-centric AI lifecycle, researchers and developers primarily focus on identifying more effective models to improve AI performance while keeping the data largely unchanged. However, this model-centric paradigm overlooks the potential quality issues and undesirable flaws of data, such as missing values, incorrect labels, and anomalies. Complementing the existing efforts in model advancement, data-centric AI emphasizes the systematic engineering of data to build AI systems, shifting our focus from model to data.

It is important to note that "data-centric" differs fundamentally from "data-driven", as the latter only emphasizes the use of data to guide AI development, which typically still centers on developing models rather than engineering data.

Why Data-centric AI?

<img width="800" src="./imgs/motivation.png" alt="motivation" />

Two motivating examples of GPT models highlight the central role of data in AI.

  • On the left, large and high-quality training data are the driving force of recent successes of GPT models, while model architectures remain similar, except for more model weights.
  • On the right, when the model becomes sufficiently powerful, we only need to engineer prompts (inference data) to accomplish our objectives, with the model being fixed.

Another example is Segment Anything, a foundation model for computer vision. The core of training Segment Anything lies in the large amount of annotated data, containing more than 1 billion masks, which is 400 times larger than existing segmentation datasets.

What is the Data-centric AI Framework?

<img width="800" src="./imgs/framework.png" alt="framework" />

Data-centric AI framework consists of three goals: training data development, inference data development, and data maintenance, where each goal is associated with several sub-goals.

  • The goal of training data development is to collect and produce rich and high-quality training data to support the training of machine learning models.
  • The objective of inference data development is to create novel evaluation sets that can provide more granular insights into the model or trigger a specific capability of the model with engineered data inputs.
  • The purpose of data maintenance is to ensure the quality and reliability of data in a dynamic environment.
