COLLAFUSE is a collaborative framework for efficient and privacy-enhanced training of generative models, balancing computational tasks between local clients and a shared server.
Streszczenie
COLLAFUSE addresses challenges in generative artificial intelligence by optimizing denoising diffusion probabilistic models through collaborative learning. It enables shared server training while retaining computationally inexpensive processes locally, enhancing privacy and reducing data sharing needs. The framework impacts various fields like edge computing solutions, healthcare research, and autonomous driving. By introducing a cut-ratio parameter, COLLAFUSE aims to balance performance, privacy, and resource utilization effectively. Initial experiments with MRI brain scans support the hypotheses that collaborative learning improves image fidelity and reduces local computational intensity.
Statystyki
T = 100 steps are used in the DDPM.
4,920 MRI scans from 123 patients each are included in the independent client datasets.
Batch size of 150 is utilized during training.
Cytaty
"As illustrated in Figure 1a, from the client’s perspective, the training sequence orchestrated by COLLAFUSE comprises six key steps."
"The findings further indicate that a decreasing cut-ratio c effectively shifts computational effort to a shared server backbone."
"Our experiment supports Hypothesis 1, showing that collaborative learning with COLLAFUSE improves image fidelity compared to non-collaborative local training (c = 1)."
