Youzhe Song (Isidore)

My research centers on building AI that not only performs well but also reasons in a way that is intuitive and trustworthy to humans.

I focus on two core questions:
1) How can we build models that have a human-intuitive, stepwise, and organic reasoning trajectory?
2) How can models understand and align information from different sources (e.g., images and text) in a human-like manner?

Research

My Ph.D. research plan is built on my experience in mechanism design and reflections on human cognition. I aim to focus on two primary capabilities of large models:

1. Building a Unified Semantic Space: My first goal is to study how to effectively map diverse information into a unified, interpretable latent space. This goes beyond cross-modal mapping—it underpins logical reasoning. I believe that efficient cross-modal semantic alignment is a first step toward foundational models that can comprehensively understand the world.

2. Realizing Structured Reasoning in Latent Space: After achieving semantic alignment, my next goal is to design structured, chain-of-thought-like reasoning trajectories within this unified latent space. I want models not only to produce answers but also to present a decomposable and traceable reasoning process.

Reading List

Each line in the list is presented with the date, book title, and author. An asterisk (*) at the end indicates a key book.

Books not read on WeChat Read cannot be traced back in time. After experiencing consecutive submission failures in mid-2023, my inner confusion and helplessness erupted, and I began reading a large number of spiritual books, seeking personal life integration. In recent years, I have made breakthroughs in my personal mindset. If we only know too much knowledge, we cannot live this life well. So after overcoming internal friction, I read fewer books.
