From Jumps to Signatures: a Generative Method for Temporal Point Processes

arXiv:2607.06652v1 Announce Type: new Abstract: Rough path signatures are a universal feature map for continuous paths and, via the expected signature, characterise path distributions. These guarantees do not directly extend to cadlag paths of Temporal Point Processes (TPPs), limiting the use of signature methods for event sequences. Furthermore, neural TPP models, including recent generative approaches, optimise per-event objectives with no global sequence-level loss, while evaluation of variable-length event sequences lacks distributional discrepancy measures. This paper proposes a common pa

Why this matters
Why now

The paper directly addresses known limitations in current generative models for temporal point processes (TPPs) and the evaluation of event sequences, signaling ongoing advancements in AI agent capabilities.

Why it’s important

Improved generative methods for TPPs can lead to more sophisticated and reliable AI agents by enabling better modeling and prediction of complex event sequences, critical for autonomous decision-making.

What changes

The ability to characterize and generate temporal event sequences more accurately moves beyond per-event objectives to a global sequence-level understanding, potentially enhancing the reliability and safety of AI systems.
