Entropic Regularization to Assist a Geologist in Producing a Geologic Map

Entropic Regularization to Assist a Geologist in Producing a Geologic Map

The gravity and magnetic data measured on the Earth’s surface or above it (collected from an aircraft flying at low altitude) can be used to assist in geologic mapping by estimating the spatial density and magnetization distributions, respectively, presumably confined to the interior of a horizontal slab with known depths to the top and bottom. To estimate density or magnetization distributions...

A Geologist Looks at the Natural Vegetation Map of Ohio

Boundaries on the new map of the Natural Vegetation of Ohio by Gordon (1966) neatly follow, in most places, geologic boundaries. Where this is not true, conditions controlling this distribution are either aspect, microclimate, or the result of some as-yet unrecognized variation in the geology. Vegetation-geology correlations may be generalized as follows. Beech (-maple) forests occur on better ...

Entropic Graph-based Posterior Regularization

Graph smoothness objectives have achieved great success in semi-supervised learning but have not yet been applied extensively to unsupervised generative models. We define a new class of entropic graph-based posterior regularizers that augment a probabilistic model by encouraging pairs of nearby variables in a regularization graph to have similar posterior distributions. We present a three-way a...

ADDGEO: An Intelligent Agent to Assist Geologist Finding Petroleum in Offshore Lands

Part of the work in finding petroleum areas consists of interpreting thin section taken from the sample rocks. Geologists uses many techniques to identifying the rock constituents, but one of the most efficient method relies on recognizing the visual pattern of the thin section using a microscope. This image recognition is a complex task that requires a lot of training. In this paper, we presen...
