什么是 Machine Learning？

RAG is not machine learning, and the ML toolkit solves the wrong problem. The article argues that despite its resemblance to ML, RAG is fundamentally a search system, not a model, making hyperparameter tuning and embedding fine-tuning ineffective and misleading.

Tensors are fundamental structures in machine learning that organize numbers, enabling models to process real-world data like text, images, and audio by converting them into numerical forms for the complete input-to-output data flow.
