Tianzhe Chu

I’m a senior-year undergraduate student major in Computer Science at ShanghaiTech University, with a wonderful year(22-23) spent in UC Berkeley. I'm working on representation learning. I'm from Suzhou.

I am currently an undergraduate researcher in Berkeley Artificial Intelligence Research Lab(BAIR) advised by Prof. Yi Ma. I'm interested in unsupervised/self-supervised representation learning and interpretable deep learning architectures. My goal is to develop principled learning techniques that model the structures of real-world information at scale, with applications on visual recognition, 3D generation, multimodality, etc.


Fall 2024: I'm applying for Ph.D. in Machine Learning & Computer Vision.

Nov 2023: Our paper CRATE-Segmentation was accepted by CPAL 2024 and NeurIPS 2023 XAI Workshop, both as Oral! Note: see here for what's CPAL.

Nov 2023: New preprint! We present the comprehensive version of CRATE.

Sep 2023: Our paper CRATE(white-box transformer) was accepted by NeurIPS 2023!

May 2023: Gonna leave lovely Berkeley (as well as U.S.), finishing 7 tech courses and a few interesting research projects.

The white-box transformer leads to the emergence of segmentation properties in the network's self-attention maps, solely through a minimalistic supervised training recipe.

PontTuset Image Clustering via the Principle of Rate Reduction in the Age of Pretrained Models

This paper proposes a novel image clustering pipeline that integrates pre-trained models and rate reduction, enhancing clustering accuracy and introducing an effective self-labeling algorithm for unlabeled datasets at scale.

PontTuset White-Box Transformers via Sparse Rate Reduction
Yaodong Yu, Sam Buchanan, Druv Pai, Tianzhe Chu, Ziyang Wu, Shengbang Tong, Benjamin D. Haeffele, Yi Ma
Accepted by NeurIPS 2023

We develop white-box transformer-like deep network architectures which are mathematically interpretable and achieve performance very close to ViT.

PontTuset White-Box Transformers via Sparse Rate Reduction: Compression Is All There Is?

We propose CRATE(comprehensive version), a “white-box” transformer neural network architecture with strong performance at scale. “White-box” means we derive each layer of CRATE from first principles, from the perspective of compressing the data distribution with respect to a simple, local model. CRATE has been extended to MAE, DINO, BERT, and more transformer-based frameworks.

PontTuset Masked Completion via Structured Diffusion with White-Box Transformers
Sam Buchanan, Ziyang Wu, Druv Pai, Tianzhe Chu, Yaodong Yu, Yi Ma
Under Review, Accepted by CPAL 2024(non-archival track)
project page / In coming!

We exploit a connection between denoising diffusion models and compression to construct white-box masked autoencoders from first principles.
