Algorithms for Image Analysis and Combination of Pattern Classifiers with Application to Medical Diagnosis

Authors: Harris V Georgiou
Comments: 12 Pages.

Medical Informatics and the application of modern signal processing in the assistance of the diagnostic process in medical imaging is one of the more recent and active research areas today. This thesis addresses a variety of issues related to the general problem of medical image analysis, specifically in mammography, and presents a series of algorithms and design approaches for all the intermediate levels of a modern system for computer-aided diagnosis (CAD). The diagnostic problem is analyzed with a systematic approach, first defining the imaging characteristics and features that are relevant to probable pathology in mammo-grams. Next, these features are quantified and fused into new, integrated radio-logical systems that exhibit embedded digital signal processing, in order to improve the final result and minimize the radiological dose for the patient. In a higher level, special algorithms are designed for detecting and encoding these clinically interest-ing imaging features, in order to be used as input to advanced pattern classifiers and machine learning models. Finally, these approaches are extended in multi-classifier models under the scope of Game Theory and optimum collective deci-sion, in order to produce efficient solutions for combining classifiers with minimum computational costs for advanced diagnostic systems. The material covered in this thesis is related to a total of 18 published papers, 6 in scientific journals and 12 in international conferences.

The Human Computer Science of 13,800,000,000 B.C.

Authors: Rodney Bartlett

The hardest part of writing this was selecting a category. It involves physics, maths, biology, philosophy. But it speaks of computer science and the AI of bits being responsible for all creation. So maybe this is the right category? This article is another version of my entry in FQXi’s 2014 contest – I was inspired to write this new version after reading "The Missing Universe" by Bob Berman (Astronomy magazine - April 2014) which says, "... MOND (MOdified Newtonian Dynamics) works well in predicting how galaxies rotate, but it doesn't work as well in predicting motions at much larger scales, such as those between galaxy groups (clusters and superclusters - DM, dark matter, seems compelling at the largest scales)." This sounds like a message from the universe that we don't have to choose between dark matter and modified gravity. The following article shows that they can be integrated. And if a Theory of Everything really does describe the universe, the strong force and electromagnetic force (p.28 of Bob Berman's article) must also be capable of integration with DM/MOND. To do this, I'll "Einsteinize" my article by reminding readers of a 1919 paper he wrote. Further Einsteinization will return us to the Theory of Everything by speaking of his Unified Field Theory. Then I’ll finish with “What is Gravity?” (thanks to Einstein’s General Relativity explaining that gravity is the warping of space-time, this could also be called “What is Space-time?”) and a new interpretation of infinity.
