From Empirical to Scientific Knowledge

What if everything we think we know about AI understanding is wrong? Is compression the key to intelligence? Or is there something more—a leap from memorization to true abstraction?

In this fascinating conversation, we sit down with **Professor Yi Ma**—world-renowned expert in deep learning, IEEE/ACM Fellow, and author of the groundbreaking new book *Learning Deep Representations of Data Distributions*. Professor Ma challenges our assumptions about what large language models actually do, reveals why 3D reconstruction isn't the same as understanding, and presents a unified mathematical theory of intelligence built on just two principles: **parsimony** and **self-consistency**.

Key Insights:

**LLMs Don't Understand—They Memorize**

Language models process text (*already* compressed human knowledge) using the same mechanism we use to learn from raw data.

**The Illusion of 3D Vision**

Sora and NeRFs etc that can reconstruct 3D scenes still fail miserably at basic spatial reasoning

**"All Roads Lead to Rome"**

Why adding noise is *necessary* for discovering structure.

**Why Gradient Descent Actually Works**

Natural optimization landscapes are surprisingly smooth—a "blessing of dimensionality"

**Transformers from First Principles**

Transformer architectures can be mathematically derived from compression principles
