The Linearized Hellinger--Kantorovich Distance
Tianji Cai, Junyi Cheng, Bernhard Schmitzer +1
In this paper we study the local linearization of the Hellinger--Kantorovich distance via its Riemannian structure. We give explicit expressions for the logarithmic and exponential…

Linearized Optimal Transport for Collider Events
Tianji Cai, Junyi Cheng, Katy Craig +1
We introduce an efficient framework for computing the distance between collider events using the tools of Linearized Optimal Transport (LOT). This preserves many of the advantages…
