摘要:

近年来,深度神经网络(DNNs)在各种人工智能系统中的普遍应用,促使它们被采用来解决具有挑战性的可视化问题。尽管复杂的DNNs具有出色的泛化能力,但理解其预测相关的质量、置信度、鲁棒性和不确定性是至关重要的。对这些量的透彻理解能产生可操作的见解,帮助应用科学家做出明智的决策。遗憾的是,DNNs的内在设计原理无法产生预测不确定性,这需要为各种可视化应用单独制定鲁棒的感知不确定性的模型。为此,本贡献展示了如何使用各种方法高效地估计DNNs的预测不确定性和敏感性,然后在深度图像合成任务中进行交互式比较和对照。我们的检查表明,感知不确定性的深度可视化模型能生成具有信息量且质量和多样性更高的插图。此外,预测不确定性提高了深度可视化模型的鲁棒性和可解释性,使其对于依赖视觉分析的各种科学领域变得实用和便捷。

英文摘要:

Ubiquitous applications of Deep neural networks (DNNs) in different artificial intelligence systems have led to their adoption in solving challenging visualization problems in recent years. While sophisticated DNNs offer an impressive generalization, it is imperative to comprehend the quality, confidence, robustness, and uncertainty associated with their prediction. A thorough understanding of these quantities produces actionable insights that help application scientists make informed decisions. Unfortunately, the intrinsic design principles of the DNNs cannot beget prediction uncertainty, necessitating separate formulations for robust uncertainty-aware models for diverse visualization applications. To that end, this contribution demonstrates how the prediction uncertainty and sensitivity of DNNs can be estimated efficiently using various methods and then interactively compared and contrasted for deep image synthesis tasks. Our inspection suggests that uncertainty-aware deep visualization models generate illustrations of informative and superior quality and diversity. Furthermore, prediction uncertainty improves the robustness and interpretability of deep visualization models, making them practical and convenient for various scientific domains that thrive on visual analyses.
