Hello there

About me

I am YU Yue (Will), an undergraduate at the University of Hong Kong.

Research

My research interest includes machine learning system, neural rendering, in-memory computing, and computer architecture.

NeRF

Neural radiance field (NeRF) implicitly represents a 3D scene with a multi-layer perceptron (MLP) $F: (\boldsymbol{x}, \boldsymbol{d}) \rightarrow (\boldsymbol{c}, \sigma)$ for some position $\boldsymbol{x} \in \mathbb{R}^3$, view direction $\boldsymbol{d} \in [0, \pi) \times [0, 2\pi)$, color $\boldsymbol{c}$, and "opacity" $\sigma$. Rendered results are spectacular.

I am currently working on rapid and accurate 3D reconstruction of real-world scenes with NeRF. See my posts (link) on NeRF.

MLSys

Needle is a deep learning library with customized GPU and NumPy CPU backend. The project is still in progress; see my repository for details.

To infinity and beyond^[1]

Ever though of achieving $65$% test accuracy on CIFAR-10 with merely $10$ data points? It is achieved with neural tangent kernel (NTK). This is the way.^[2]

1. "To infinity and beyond" is a catchphrase by Buzz Lightyear from the Pixar animation film Toy Story. It is cited here to indicate NTK enables an infinitely wide hidden layer in neural networks. ↩︎

2. "This is the way" is a line from the Star Wars series the Mandalorian, which describes the "Mando" style. It is cited here to emphasize only NTK may achieve such an unbelievable result as dataset distillation. ↩︎
