Bayesian Optimization for Learning Gaits under Uncertainty An experimental comparison on a dynamic bipedal walker

Designing gaits and corresponding control policies is a key challenge in robot locomotion. Even with a viable controller parameterization, finding nearoptimal parameters can be daunting. Typically, this kind of parameter optimization requires specific expert knowledge and extensive robot experiments. Automatic black-box gait optimization methods greatly reduce the need for human expertise and t...

Walker groups

A reformulation of Walker’s theorem on the cancellation of Z says that any two homomorphisms from an abelian group B onto Z have isomorphic kernels. It does not have a constructive proof, even for B a subgroup of Z3. In this paper we give a constructive proof of Walker’s theorem for B a direct sum, over any discrete index set, of groups of the following two kinds: finite-rank torsion-free group...

Dandy-Walker Syndrome

Dandy-Walker Syndrome is a congenital brain defect in humans [4] characterized by malformations to the cerebellum [5], the part of the brain that controls movement, and to the ventricles, the fluid-filled cavities that surround the cerebellum [5]. The syndrome is named after physicians Walter Dandy and Arthur Walker, who described associated signs and symptoms of the syndrome in the 1900s. The ...

Ballistic random walker.

We introduce and investigate the scaling properties of a random walker that moves ballistically on a two-dimensional square lattice. The walker is scattered ~changes direction randomly! every time it reaches a previously unvisited site, and follows ballistic trajectories between two scattering events. The asymptotic properties of the density of unvisited sites and the diffusion exponent can be ...
