Subjective and empirical probabilities (and also logic and probability theory) are tied together by using ground atomic formulas to represent elementary events.  ...  Subjective probabilities, for the authors, are probabilities syntactically attached to the sentences of the language, and are distinguished from empirical probabilities, which are assigned to random events  ... 

Subjective logic operators in trust assessment: an empirical study

Federico Cerutti, Lance M. Kaplan, Timothy J. Norman, Nir Oren, Alice Toniolo
2014 Information Systems Frontiers  
Subjective Logic (SL) has been widely adopted as the core of such systems via its fusion and discount operators.  ...  In recent research we revisited the semantics of these operators to explore an alternative, geometric interpretation.  ...  An empirical evaluation of the graphical operators on real cases, e.g. (Guha et al. 2004) , is already envisaged as the main future work.  ...

On a Geometric Representation of Probability Laws and of a Coherent Prevision-Function According to Subjectivistic Conception of Probability

Pierpaolo Angelini, Angela De Sanctis
2018 Ratio Mathematica  
We give a geometric representation of these laws P and of a coherent prevision function P which we previously defined in an original way.  ...  We distinguish the two extreme aspects of the logic of certainty by identifying their corresponding structures into a linear space.  ...  On a Geometric Representation of Probability Laws and of a Coherent Prevision-Function There are no unpaired elements, with P(E i ) which is an evaluation of probability of E i .  ...

Specific Features of the Relationships between Operational Structures within Preschoolers' Systems of Thought

Irina N. Pogozhina
2018 Psychology in Russia: State of Art  
However, there has been no empirical verification of the significant links between the levels of development of an individual's logical-mathematical and spatial-temporal operations in his/her system of  ...  Piaget's hypothesis that the development of the logical-mathematical and spatial operations within a child's thinking system is an interconnected process has received statistical justification in this  ...  Conclusion As a result of our empirical research, we found that the operational structures of preschoolers' thinking systems operate and develop in an interconnected manner, so that an increase of the  ...

Poincaré and the Invention of Convention [chapter]

Janet Folina
2014 The Western Ontario Series in Philosophy of Science  
Logic is empty, so it is not a source of significant information. Mathematics is not empty; so logicism -the view that at least arithmetic (and possibly more of mathematics) is logic -must be false.  ...  Rather, it mandates empirically motivated shifts in (even geometric) conventions -a view surprisingly in accord with Friedman's "relativized a priori", and thus more consistent with general relativity  ...  Though our experience of approximate rigid bodies provides an empirical precondition for our having the geometrical concepts (70), the subject matter of (pure) geometry is ideal. 7 Poincaré's preconditions  ...

An Empirical Evaluation of the Approximation of Subjective Logic Operators Using Monte Carlo Simulations [article]

Fabio Massimo Zennaro and Magdalena Ivanovska and Audun Jøsang
2019 arXiv   pre-print
Concretely, we apply our method to the relevant case study of the subjective logic operator for binomial multiplication and fusion, and we study empirically their degree of approximation.  ...  In order to evaluate this bias, we propose an experimental protocol that exploits Monte Carlo simulations and their properties to assess the distance between the result produced by subjective logic operators  ...  The authors would like to express their gratitude to the anonymous reviewers who commented on the first version of this article and helped improving it.  ...

Language, cognition, and the nature of modularity: Evidence from aphasia

Rosemary Varley, Michael Siegal
2002 Behavioral and Brain Sciences  
We examine Carruthers's proposal that sentences in logical form serve to create flexibility within central system modularity, enabling the combination of information from different modalities.  ...  Other challenges for a logical form account are noted.  ...  But this inference is an imprecise and indirect metric of the integrity of logical form.  ...

A Method for Assessment of Segmentation Success Considering Uncertainty in the Edge Positions

Rubén Usamentiaga, Daniel F García, Carlos López, Diego González
2006 EURASIP Journal on Advances in Signal Processing  
The technique is based on a comparison of the segmentation produced by an algorithm with an ideal segmentation. The procedure to obtain the ideal segmentation is described in detail.  ...  Several alternatives for the fuzzy membership functions, based on statistical properties of the possible positions of each edge, are defined.  ...  For example, in [6] , an empirical procedure is proposed which is based on subjective human assessment.  ...
