Due to process scaling, variability in process, voltage, and temperature (PVT) parameters leads a significant parametric yield loss, thus impacts the optimization for circuit designs seriously. Previous algorithms are limited optimizing either power or timing separately, without combining them together simultaneous optimization. However, neglecting negative correlation between performance metrics, such as measurements, will bring on accuracy loss. This paper suggests an efficient...

With the successful integration of contrastive learning and graph neural networks, (GCL) has demonstrated superior performance in representation learning. Majority earlier works tend to utilize dual-view frameworks. However, they require high computational costs; additionally, we observed that can hardly obtain robust result as training processes swing between two important metrics: alignment uniformity. We address these problems by designing a novel single-view paradigm called Light...

The problem of graph classification in neural networks has received extensive research. In the tasks, pooling is one important research directions, which aims to reduce dimensionality representation and obtain prediction label for entire graph. However, due fixed compression quotas node discarding strategies, commonly adopted hierarchical methods often suffer structure destruction information loss.
