摘要:

虽然我们已经看到了大量用于推荐可视化的算法,但这些算法很少相互比较,因此很难确定哪种算法最适合给定的视觉分析场景。虽然已经提出了几个正式的框架作为回应,我们认为这个问题仍然存在,因为可视化推荐算法从评估的角度来看是不充分的指定。在本文中,我们提出了一个以评估为中心的框架,上下文和比较广泛的可视化推荐算法。我们提出了我们的框架的结构,其中使用三个组件指定算法:(1)表示可能的可视化设计的整个空间的图,(2)用于遍历图的潜在候选人推荐的方法,以及(3)用于对候选设计进行排名的预言。为了证明我们的框架如何指导算法性能的正式比较,我们不仅从理论上比较了五个现有的代表性推荐算法,而且还从经验上比较了四个新的算法,根据我们的研究结果从理论上比较。我们的研究结果表明,这些算法在用户性能方面表现相似,突出了需要更严格的正式比较推荐算法,以进一步阐明其在各种分析场景中的好处。

英文摘要:

Although we have seen a proliferation of algorithms for recommending visualizations, these algorithms are rarely compared with one another, making it difficult to ascertain which algorithm is best for a given visual analysis scenario. Though several formal frameworks have been proposed in response, we believe this issue persists because visualization recommendation algorithms are inadequately specified from an evaluation perspective. In this paper, we propose an evaluation-focused framework to contextualize and compare a broad range of visualization recommendation algorithms. We present the structure of our framework, where algorithms are specified using three components: (1) a graph representing the full space of possible visualization designs, (2) the method used to traverse the graph for potential candidates for recommendation, and (3) an oracle used to rank candidate designs. To demonstrate how our framework guides the formal comparison of algorithmic performance, we not only theoretically compare five existing representative recommendation algorithms, but also empirically compare four new algorithms generated based on our findings from the theoretical comparison. Our results show that these algorithms behave similarly in terms of user performance, highlighting the need for more rigorous formal comparisons of recommendation algorithms to further clarify their benefits in various analysis scenarios.
