Analog In-Memory Computing with Uncertainty Quantification for Efficient Edge-based Medical Imaging Segmentation
arxiv(2024)
摘要
This work investigates the role of the emerging Analog In-memory computing
(AIMC) paradigm in enabling Medical AI analysis and improving the certainty of
these models at the edge. It contrasts AIMC's efficiency with traditional
digital computing's limitations in power, speed, and scalability. Our
comprehensive evaluation focuses on brain tumor analysis, spleen segmentation,
and nuclei detection. The study highlights the superior robustness of isotropic
architectures, which exhibit a minimal accuracy drop (0.04) in analog-aware
training, compared to significant drops (up to 0.15) in pyramidal structures.
Additionally, the paper emphasizes IMC's effective data pipelining, reducing
latency and increasing throughput as well as the exploitation of inherent noise
within AIMC, strategically harnessed to augment model certainty.
