2016

This thesis aims at considering the information as essential link between the sciences of the nature and the human sciences. It is mainly refered to principles of the natural science, allied in a set of scientific stemming approaches, in particular, theories of the complexity, of chaos, of information, auto-organization, emergences and ecosystems. The laws of the thermodynamics play a central role in this context, where the organization and the negentropy make directly part of the field of information production. There is in particular refered to Law of maximization of entropy Production (or, in other words, of energy dissipation), among which the incidence on the functioning and the behavi…

Diffusion equations with negentropy applied to denoise mammographic images.

2006

Mammography is a radiographic technique used for the detection of breast lesions. The analysis of the digital image normally requires a previous application of filters as a preprocessing step to reduce the noise level of the image, while preserving important details to carry out a suitable diagnostic. In the literature, there are a large amount of denoising techniques applied to different medical images. In this work we have studied the performance of a diffusive filter with a stopping condition based on the statistical concept of negentropy, applied to denoise mammographic images. The negentropy has been succesfully prove with other denoising methods as independent component analysis by th…

Completing the logarithmic scoring rule for assessing probability distributions

2012

We propose and motivate an expanded version of the logarithmic score for forecasting distributions, termed the Total Log score. It incorporates the usual logarithmic score, which is recognised as incomplete and has been mistakenly associated with the likelihood principle. The expectation of the Total Log score equals the Negentropy plus the Negextropy of the distribution. We examine both discrete and continuous forms of the scoring rule, and we discuss issues of scaling for scoring assessments. The analysis suggests the dual tracking of the quadratic score along with the usual log score when assessing the qualities of probability distributions. An application to the sequential scoring of f…
