Rational partition models under iterative proportional scaling
Jane Ivy Coons, Carlotta Langer, Michael Ruddy
In this work we investigate partition models, the subset of log-linear models for which one can perform the iterative proportional scaling (IPS) algorithm to numerically compute th…
The moving frame method for iterated-integrals: orthogonal invariants
Joscha Diehl, Rosa Preiß, Michael Ruddy +1
Geometric features, robust to noise, of curves in Euclidean space are of great interest for various applications such as machine learning and image analysis. We apply the Fels-Olve…
Signatures of algebraic curves via numerical algebraic geometry
Timothy Duff, Michael Ruddy
We apply numerical algebraic geometry to the invariant-theoretic problem of detecting symmetries between two plane algebraic curves. We describe an efficient equality test which de…
Maximum likelihood degree of the two-dimensional linear Gaussian covariance model
Jane Ivy Coons, Orlando Marigliano, Michael Ruddy
In algebraic statistics, the maximum likelihood degree of a statistical model is the number of complex critical points of its log-likelihood function. A priori knowledge of this nu…
Differential signatures of algebraic curves
Irina A. Kogan, Michael Ruddy, Cynthia Vinzant
In this paper, we adapt the differential signature construction to the equivalence problem for complex plane algebraic curves under the actions of the projective group and its subg…
The classification and curvature of biquotients of the form
Jason DeVito, Robert DeYeso, Michael Ruddy +1
We show there are precisely 15 inhomogeneous biquotients of the form and show that at least 8 of them admit metrics of quasi-positive curvature.
