Department of Electrical and Computer Engineering, Florida International University.

I‘m a Ph.D. Candidate in the Department of Electrical and Computer Engineering at Florida International University (FIU), where I work as a Graduate Research&Teaching Assistant in Dr. Ou Bai’s Human Cyber-Physical Systems (HCPS) Laboratory. My research focuses on the intersection of Computer Vision, Deep Learning, Embedded Systems, and Multimodal Large Language Models (MLLMs), with an emphasis on real-time, resource-constrained, and wearable AI systems. I have published research in venues across multimedia, biometrics, computer vision, and natural language processing at the top international AI conferences with total .

Currently, I’m working on an AI-powered wearable multimodal multi-task real-time dynamic behavior analysis system, aiming to integrate perception, reasoning, and decision-making into embedded and edge AI platforms. Particularly interested in efficient multimodal LLM inference, model compression, and edge/embedded AI deployment, with the goal of enabling intelligent systems to operate reliably under strict latency, computation, and energy constraints. My research has been applied to a range of real-world cyber-physical systems, including wearable exoskeletons, multimodal emotion recognition, and human–AI interaction systems.

MTCAE-DFER: Multi-Task Cascaded Autoencoder for Dynamic Facial Expression Recognition

Peihao Xiang, Kaida Wu, Ou Bai

IEEE 9th International Joint Conference on Biometrics

8-11 September, 2025 | Osaka, Japan

[IJCB 2025][arXiv][Code]

  • MTCAE-DFER learns robust spatiotemporal facial representations for dynamic expression recognition by cascading autoencoders under a multi-task learning framework that jointly optimizes reconstruction and classification.

Label Ranker: Self-aware Preference for Classification Label Position in Visual Masked Self-supervised Pre-trained Model

Peihao Xiang, Kaida Wu, Ou Bai

ACM 15th International Conference on Multimedia Retrieval

30 June - 3 July, 2025 | Chicago, IL, USA

[ICMR 2025][Paper][Preprints][Code][Video]

  • Label Ranker introduces a self-aware label positioning mechanism for visual masked self-supervised pre-trained models (e.g., MAE-style architectures). It observes that the position at which a classification label (or token) is injected into the model significantly affects downstream performance, yet is usually treated as a fixed or arbitrary design choice.

MultiMAE-DER: Multimodal Masked Autoencoder for Dynamic Emotion Recognition

Peihao Xiang, Chaohao Lin, Kaida Wu, Ou Bai

IEEE 14th International Conference on Pattern Recognition Systems

15-18 July, 2024 | University of Westminster, London, UK

[ICPRS 2024][Paper][arXiv][Code][Video]

  • MultiMAE-DER proposes a multimodal masked autoencoder framework for dynamic emotion recognition (DER) that learns robust temporal–emotional representations by jointly modeling multiple modalities (e.g., visual, audio, and physiological signals).
