Research
I did resaerch in AI for healthcare in my undergrad study, and now I am working on federated learning.
My current project is about multiple model federated learning (MMFL): local clients handle multiple FL models at the same time.
In this scenario, how to select clients, and assign them with different training tasks is really important to improve the performance of the system.

Poster: Optimal Variance-Reduced Client Sampling for Multiple Models Federated Learning

Supplementary material
This paper explores an MMFL scenario where each client is restricted to training only one model per global round due to limited computational resources.
We propose a client sampling and task assignment method that theoretically minimizes the variance of global updates. The method achieves a 30% higher accuracy than the baseline.

In the real-world scenario, clients could contribute to multiple federated learning models' training at the same time.
For example, a company may update their keyboard prediction model, speech recognition model, and other more federated learning models on your phone.
In this paper, we propose a client-task assignment strategy to preserve the fairness across multiple training tasks.

Efficient 3D Transformer with cluster-based Domain-Adversarial Learning for 3D Medical Image Segmentation
Haoran Zhang, Hao Chen
ISBI (one of the best conferences in medical image processing), 2023
We proposed a pyramidally downsampled 3D Transformer to boost efficiency and maintain high segmentation accuracy.
We also proposed a cluster-based domain-adversarial learning method to exploit available domains at a fine-grained level.

About Me
I was born in Xinxiang, China. The meaning of "Xin-Xiang" is "New-York".
My family name is 张 (Zhang), which is one of the most common family names in China.
And my given name is 皓然 (Haoran), 皓(Hao) means "the color of the moon", 然(Ran) doesn't have a specific meaning, maybe it means "yeah, uh-huh".
I like watching movies and football (soccer). I support Bayern Munich and Manchester City!
