Galois Connections with Hedges

We introduce (fuzzy) Galois connections with hedges. Fuzzy Galois connections are basic structures behind so-called formal concept analysis of data with fuzzy attributes. Introducing hedges to Galois connections means introducing two parameters. The parameters influence the size of the set of all the fixpoints of a Galois connection. In the sense of formal concept analysis, the fixpoints, calle...

Connections with Bohmian Mechanics

OF THE DISSERTATION Connections with Bohmian Mechanics by James Oliver Taylor Dissertation Director: Sheldon Goldstein We begin by formulating non-relativistic Bohmian mechanics for theories in which the wave functions are sections of a Hermitian vector bundle over a Riemannian manifold. We give geometric interpretations of the Pauli equation and the Dirac equation. We then explain the influenc...

ICA with Sparse Connections

When applying independent component analysis (ICA), sometimes we expect that the connections between the observed mixtures and the recovered independent components (or the original sources) to be sparse, to make the interpretation easier or to reduce the model complexity. In this paper we propose natural gradient algorithms for ICA with a sparse separation matrix, as well as ICA with a sparse m...

A fire with global connections

Indonesia has been suffocating under an orange haze for months. By the end of October, half a million people had been treated for respiratory problems caused by the polluted air. Schools had to close and children were evacuated by military vessels in the worst affected areas. At times, the haze even affected northern neighbours Vietnam and Cambodia. The habitual slash-and-burn approach of local...
