Learning to Parse Images

... Neal [4] introduced generative models composed of multiple layers of stochastic logistic units connected in a directed acyclic graph. In general, as each unit has multiple parents, it is intractable to compute the posterior distribution over hidden variables when certain variables are observed. Howe ...

from Converse PDL - School of Computer Science

... We show that is possible to eliminate the "converse" operator from CPDL, without compromising the soundness and completeness of inference for it. Specifically we present an intuitive encoding of CPDL formulae into PDL that eliminates the converse programs from a CPDL formula, but adds enough informa ...

A Decision Procedure for a Fragment of Linear Time Mu

... Gµ formulas and prove that every closed formula can be transformed into this form. GPF decomposes a formula into the present and future parts. The present part is the conjunction of atomic propositions or their negations while the future part is the conjunction of elements in the closure of a given ...

Using fuzzy temporal logic for monitoring behavior

... value of the proposition V isibleBall will be a real number between 0 and 1 reflecting our incapacity to draw clear boundaries between thruthness and falseness of a proposition. This allows us to include fuzzy statements such as “slightly visible” or “completely visible”. On the other hand, it is no ...

Unsupervised Object Counting without Object Recognition

... a straightforward approach would be to perform explicit object detection [5], [7], [12]–[14]. Also, regression-based approaches have been proposed, which translate the image features into the number of objects with a regression model [8], [15], [16]. These approaches require labeled training data, w ...

Thus for point features the worst-case number of hypotheses is O(m3n3). The implementation that we describe below relies ...

First-Order Extension of the FLP Stable Model

Though rule arrows (←) are treated like usual implications in the FOL-representation of Π, they are distinguished in the definition of Π4 (u) because of the presence of ’B∧’ in (7).
