Model-centric AI

Model-centric AI is a design principle in the field of Artificial Intelligence (AI) that emphasizes on the development and refinement of the models over software engineering. Instead of manually writing rules or programming for every situation, model-centric AI relies on training models based on vast amounts of data and allows the model to learn rules from this data.

How Model-centric AI works

In the model-centric AI approach, the model is at the core of the system. Rather than writing explicit rules in the program, a model-centric AI system learns these rules from data. This is often achieved through machine learning techniques where the system is trained on a dataset. The model learns to predict outcomes based on the patterns it identifies from the given data. For instance, in an image recognition AI, the model would be trained on millions of images, learning to identify and categorize different objects or features from these images.

A key aspect of a model-centric AI design approach is the iterative process of improving the model. The model is initially trained on a dataset, then its performance is evaluated, often on a separate test dataset. Based on the evaluation, adjustments are made to the model, and it is retrained. This iterative feedback loop - training, evaluation, adjustment - ensures the continual improvement of the model.

As more data becomes available, the model can be retrained and fine-tuned to improve its performance and to adapt to new patterns in the data. This contrasts with traditional software engineering approaches, where adjustments have to be manually coded into the software whenever a change is needed. Model-centric AI, therefore, offers greater flexibility and the potential for more powerful and efficient AI systems.
