AI总结:

ConTSG-Bench 提出一个统一基准,用于评估条件时间序列生成模型在不同条件下的性能和可控性。

摘要:

条件时间序列生成在解决数据稀缺问题和实现实验分析中起着关键作用。尽管其重要性日益增加,但该领域缺乏一个标准化和系统化的基准评估框架,用于评估生成模型在不同条件下的表现。为解决这一差距,我们引入了条件时间序列生成基准(ConTSG-Bench)。ConTSG-Bench包含一个大规模、对齐良好的数据集,涵盖了多样化的条件模态和语义抽象层次,首次使生成方法在这些维度上的系统评估成为可能,通过全面的生成保真度和条件符合度指标套件。定量基准评估和对条件生成行为的深入分析揭示了当前方法的特性和局限性,突显了关键挑战和有前途的研究方向,特别是关于在复杂条件下精确的结构可控性和下游任务实用性。

英文摘要:

Conditional time series generation plays a critical role in addressing data scarcity and enabling causal analysis in real-world applications. Despite its increasing importance, the field lacks a standardized and systematic benchmarking framework for evaluating generative models across diverse conditions. To address this gap, we introduce the Conditional Time Series Generation Benchmark (ConTSG-Bench). ConTSG-Bench comprises a large-scale, well-aligned dataset spanning diverse conditioning modalities and levels of semantic abstraction, first enabling systematic evaluation of representative generation methods across these dimensions with a comprehensive suite of metrics for generation fidelity and condition adherence. Both the quantitative benchmarking and in-depth analyses of conditional generation behaviors have revealed the traits and limitations of the current approaches, highlighting critical challenges and promising research directions, particularly with respect to precise structural controllability and downstream task utility under complex conditions.
