Abstract:
The persistence diagram of a real-valued
function on a topological space is a
multi-set of points in the extended plane.
We prove that under mild assumptions on the
function, the persistence diagram is stable:
small changes in the function imply only
small changes in the diagram. We apply this
result to estimating the homology of sets in
a metric space and to comparing and
classifying geometric shapes.
