> Title: Shape space and models for functional data
>
>
> Abstract: Statements such as “death rate curve needs to remain single
> peaked”; “we expect the second peak of infected cases to be smaller
> compared to the first”, are, unfortunately, all too familiar nowadays. They
> represent instances of informal descriptions of shapes of functions we can
> relate to readily, wherein the notion of shape relates exclusively to ‘y
> direction’ variation. To formalise this, in this talk, I will consider a
> group-theoretic description of the shape of a function as that which is
> left behind once ‘x direction’ variability is ignored: only the number and
> values of local extrema are relevant to describe its shape and not their
> timings. Accordingly, the shape of a function is shown to be uniquely
> encoded by a polynomial, and this connection allows us to study structural
> aspects of the shape space of functions.
>
>
>
> For statistical analysis of functional data (e.g., densely sampled
> multiple time series data) the upside to this perspective is that (i) a
> natural dimension reduction mechanism based on local extrema becomes
> available when analysing amplitudes that avoids the task of registering
> (or aligning) the data; and (ii) simple finite-dimensional generative shape
> models can be defined. On the other hand, geometry of the shape space is
> complicated, and this makes it difficult to compute descriptive statistics
> (e.g., average shape) and study models induced on the shape space from the
> original (simpler) function space.
