Belief hedges: Measuring ambiguity for all events and all models
نویسندگان
چکیده
We introduce belief hedges, i.e., sets of events whose uncertain subjective beliefs neutralize each other. Belief hedges allow us to measure ambiguity attitudes without knowing those beliefs. They lead improved indexes that are valid under all popular theories. Our can be applied real-world problems and do not require expected utility for risk or commitments two-stage optimization, thereby increasing their descriptive power. make theories widely applicable.

Integrated Care: A Pill for All Ills?
There is an increasing policy emphasis on the integration of care, both within the healthcare sector and also between the health and social care sectors, with the simple aim of ensuring that individuals get the right care, in the right place, at the right time. However, implementing this simple aim is rather more complex. In this editorial, we seek to make sense of this complexity and ask: what...
متن کاملJustifying all the fuss about false belief.
The classic study by Wimmer and Perner showed that children below the age of about 4 years of age fail to appreciate others' false beliefs. This opened the floodgates to the theory-of-mind research programme. Recently, a study by Riggs and Simpson has called the central challenge of false belief into question, reporting similar difficulties with true belief. I would argue, however, that not onl...
متن کاملKnowledge Means 'All', Belief Means 'Most'
We introduce a bimodal epistemic logic intended to capture knowledge as truth in all epistemically alternative states and belief as a generalized ‘majority ’ quantifier, interpreted as truth in many (a ‘majority ’ of the) epistemically alternative states. This doxastic interpretation is of interest in KR applications and it also has an independent philosophical and technical interest. The logic...
متن کاملTemporal Events in All Dimensions and Scales
This paper describes a new representation for the audio and visual information in a video signal. We reduce the dimensionality of the signals with singular-value decompo-sitions (SVD) or mel-frequency cepstral coefficients (MFCC). We apply these transforms to word, (word transcript , semantic space or latent semantic indexing), image (color histogram data) and audio (timbre) data. Using scale-s...
متن کاملDynamic Frailty and Change Point Models for Recurrent Events Data
Abstract. We present a Bayesian analysis for recurrent events data using a nonhomogeneous mixed Poisson point process with a dynamic subject-specific frailty function and a dynamic baseline intensity func- tion. The dynamic subject-specific frailty employs a dynamic piecewise constant function with a known pre-specified grid and the baseline in- tensity uses an unknown grid for the piecewise ...
