Analysis of AI Model 3 Works

The provided image illustrates the three core stages of how AI models operate: Learning, Inference, and Data Generation.

1. Learning

  • Goal: Knowledge acquisition and parameter updates. This is the stage where the AI “studies” data to find patterns.
  • Mechanism: Bidirectional (Feed-forward + Backpropagation). It processes data to get a result and then goes backward to correct errors by adjusting internal weights.
  • Key Metrics: Accuracy and Loss. The objective is to minimize loss to increase the model’s precision.
  • Resource Requirement: Very High. It requires high-performance server clusters equipped with powerful GPUs like the NVIDIA H100.

2. Inference (Reasoning)

  • Goal: Result prediction, classification, and judgment. This is using a pre-trained model to answer specific questions (e.g., “What is in this picture?”).
  • Mechanism: Unidirectional (Feed-forward). Data simply flows forward through the model to produce an output.
  • Key Metrics: Latency and Efficiency. The focus is on how quickly and cheaply the model can provide an answer.
  • Resource Requirement: Moderate. It is efficient enough to be feasible on “Edge devices” like smartphones or local PCs.

3. Data Generation

  • Goal: New data synthesis. This involves creating entirely new content like text, images, or music (e.g., Generative AI like ChatGPT).
  • Mechanism: Iterative Unidirectional (Recurring Calculation). It generates results piece by piece (token by token) in a repetitive process.
  • Key Metrics: Quality, Diversity, and Consistency. The focus is on how natural and varied the generated output is.
  • Resource Requirement: High. Because it involves iterative calculations for every single token, it requires more power than simple inference.

Summary

  1. AI processes consist of Learning (studying data), Inference (applying knowledge), and Data Generation (creating new content).
  2. Learning requires massive server power for bidirectional updates, while Inference is optimized for speed and can run on everyday devices.
  3. Data Generation synthesizes new information through repetitive, iterative calculations, requiring high resources to maintain quality.
