Guten Tag! I am currently working as an IT/OT & ML Senior Analyst at Accenture. Prior to joining Accenture, I served as an IDEA Research Grant Student in Prof. Dr. Manfred Claassen Group at ETH Zürich, where I obtained my Master's degree in Computer Science from RWTH Aachen University. I earned my bachelor's degree from HFUT with exceptional academic performance and was awarded four years of national scholarships. During my Bachelor's studies, I specialized in IoT and also founded the HFUT Robocup Lab. After completing my B.Sc., I worked as a computer vision working student at Siemens AG Aachen Gas Turbine Research Center while pursuing my Master's degree in Informatik at RWTH Aachen.

My research interests primarily revolve around Object Recognition, Detection, and Segmentation, as well as the Deployment of ML systems, Model Interpretability, Multi-Tasking, and Multi-Modality.

Self-supervised Learning with Temporary Exact Solutions: Linear Projection
Evrim Ozmermer, Qiang Li
Accepted by IEEE 21st International Conference on Industrial Informatics (INDIN'23), Full paper, 2023.
In this paper, we present a self-supervised learning method for training, not limited to but especially visual transformers that are able to learn meaningful representations of images and videos without requiring large amounts of labeled data. Our method is based on using exact solutions of the representations that the model generates. It is shown that the model is able to learn useful features that can be later fine-tuned on industrial downstream tasks.

Exploiting Interactivity and Heterogeneity for Sleep Stage Classification via Heterogeneous Graph Neural Network
Ziyu Jia, Youfang Lin, Yuhan Zhou, Xiyang Cai, Peng Zheng, Qiang Li, Jing Wang
Accepted by 2023 IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP),Full paper, 2023.
In this paper, we propose a novel deep model SleepHGNN for sleep stage classification. The Heterogeneous Graph Transformer is applied for capturing the interactivity and heterogeneity of the multimodal signals. To the best of our knowledge, this is the first attempt to leverage heterogeneous graph neural networks for sleep stage classification. Since the SleepHGNN is a universal framework for the graph-level classification task based on the heterogeneous graph, we will generalize model to other domains like protein classification and molecular graph classification including anticancer chemical compound classification in the future.

Continual learning on deployment pipelines for Machine Learning Systems
Qiang Li, Chongyu Zhang
Accepted by The Conference on Neural Information Processing Systems (NeurIPS), DMML Workshop, 2022.
In this work, we presented a comparison of various solutions for the deployment of machine learning systems, includes different layers of automation from highly manual model training and deployment to an automated continuous integration workflow. We proposed the evaluation metrics in practice and describe how real-world requirements differ from more academic settings.

Explainable AI: Object Recognition With Help From Background
Raza Hashmi, Qiang Li
Accepted by The International Conference on Learning Representations (ICLR), CSS Workshop, 2022.
This work explores how backgrounds might help in object recognition tasks in depth. Our project is fascinated by the baseline work done by Xiao et al. in their noise or signal paper. Website    Blogs    Camera ready video of presentation on ICLR2022    Dataset on Kaggle (130+ Download!)
