PHINN: Persistent Homology Inspired Neural Network for Rare-Event Time Series Generation
Emre Yusuf, Ren Takahashi, Jayabrata Bhaduri
Rare events in time series are critical to model but hard to learn due to data scarcity. Current generative models struggle with extreme values. We observe that rare events leave d…
