DNF Sampling for ProbLog Inference [PDF]

, 2010
Inference in probabilistic logic languages such as ProbLog, an extension of Prolog with probabilistic facts, is often based on a reduction to a propositional formula in DNF. Calculating the probability of such a formula involves the disjoint-sum-problem,

Learning to Reason: Leveraging Neural Networks for Approximate DNF Counting

, 2020
Weighted model counting (WMC) has emerged as a prevalent approach for probabilistic inference. In its most general form, WMC is #P-hard. Weighted DNF counting (weighted #DNF) is a special case, where approximations with probabilistic guarantees are ...

Learning DNF Expressions from Fourier Spectrum [PDF]

, 2012
Since its introduction by Valiant in 1984, PAC learning of DNF expressions remains one of the central problems in learning theory. We consider this problem in the setting where the underlying distribution is uniform, or more generally, a product ...

Expanded Uses of the Dorsal Nasal Flap: Redefining the Nasal Reconstruction Algorithm [PDF]

Plastic and Reconstructive Surgery, Global Open
Background:. Defects of the nose present complex reconstructive challenges to the plastic surgeon. We present our experience with using the dorsal nasal flap (DNF) to provide a durable reconstruction even in sizable defects that would otherwise be ...

Storm characteristics influence nitrogen removal in an urban estuarine environment [PDF]

Natural Hazards and Earth System Sciences, 2023
Sustaining water quality is an important component of coastal resilience. Floodwaters deliver reactive nitrogen (including NOx) to sensitive aquatic systems and can diminish water quality.

Effects of Elevated CO₂ Levels on the Growth and Yield of Summer-Grown Cucumbers Cultivated under Different Day and Night Temperatures

Agronomy, 2022
The effects of elevated CO2 (eCO2) levels on field-grown cucumbers have been extensively studied. However, the variations in photosynthate accumulation in summer-grown cucumbers simultaneously exposed to eCO2 and varying day-night temperatures (DNF ...
