Hybrid Quantum-Classical Logistic Regression for Calibrated Classification of Pulsar Candidates
Chanelle Matadah Manfouo, Donovan Slabbert, Prince Koree Osei +1
Reliable pulsar candidate ranking requires probability estimates that are not only discriminative but also well calibrated. We evaluate hybrid quantum-calssical logistic regression…
Higher lattice gauge theory from representations of 2-groups and 3+1D topological phases
Latévi M. Lawson, Prince K. Osei
We construct a higher lattice gauge theory based on the representation of 2-groups described by a category of crossed modules on a lattice model described by path 2-groupoids. Usin…
Hilbert space representation for quasi-Hermitian position-deformed Heisenberg algebra and Path integral formulation
Thomas Katsekpor, Latévi M. Lawson, Prince K. Osei +1
Position deformation of a Heisenberg algebra and Hilbert space representation of both maximal length and minimal momentum uncertainties may lead to loss of Hermiticity of some oper…
A Chern-Simons approach to self-dual gravity in (2+1)-dimensions and quantisation of Poisson structure
Prince K. Osei
The (2+1)-dimensional analog self-dual gravity which is obtained via spacetime dimension reduction of the (3+1)-dimensional Holst action without reducing the internal gauge group i…
