Learning Non-Negative Sparse Image Codes by Convex Programming
Example-based learning of codes that statistically encode general image classes is of vital importance for computational vision. Recently, non-negative matrix factorization (NMF) ...

Conformon-P Systems with Negative Values
Some initial results on the study of conformon-P systems with negative values are reported. One model of these conformon-P systems is proved to be computationally universal while a...

On Negative Bases
Abstract. We study expansions in non-integer negative base - introduced by Ito and Sadahiro [7]. Using countable automata associated with (-)-expansions, we characterize the case w...

Light Dialectica revisited
We upgrade the light Dialectica interpretation [6] by adding two more light universal quantifiers, which are both semi-computational and semi-uniform and complement each other. An...

Computational Interpretations of Analysis via Products of Selection Functions
Abstract. We show that the computational interpretation of full comprehension via two wellknown functional interpretations (dialectica and modified realizability) corresponds to t...
