Test-Time Model Adaptation with Only Forward Passes

no code implementations2 Apr 2024 Shuaicheng Niu, Chunyan Miao, Guohao Chen, Pengcheng Wu, Peilin Zhao

However, in real-world scenarios, models are usually deployed on resource-limited devices, e. g., FPGAs, and are often quantized and hard-coded with non-modifiable parameters for acceleration.

A Framework of Sparse Online Learning and Its Applications

no code implementations25 Jul 2015 Dayong Wang, Pengcheng Wu, Peilin Zhao, Steven C. H. Hoi

Unlike some existing online data stream classification techniques that are often based on first-order online learning, we propose a framework of Sparse Online Classification (SOC) for data stream classification, which includes some state-of-the-art first-order sparse online learning algorithms as special cases and allows us to derive a new effective second-order online learning algorithm for data stream classification.
