The description of an architecture—the decisions made—can be organized around these four views, and then illustrated by a few selected use cases, or scenarios which become a fifth view.

Revelation and Bible Prophecy

such a prophecy is literally an event looking forward to the physical Second Coming of Christ, rather than simply a symbolic or vague historical reference that may be clouded in apocalyptic language. The Bible is rich with repeated examples, analogies, and types (e.g., Joseph as a type or pattern of Christ). A Biblical truth might be played out

Gaussian Processes in Machine Learning

A Gaussian Process is a collection of random variables, any finite number of which have (consistent) joint Gaussian distributions. A Gaussian process is fully specified by its mean function m(x) and covariance function k(x,x0). This is a …

Object Recognition from Local Scale-Invariant Features

general assumptions on scale invariance, the Gaussian ker-nel and its derivatives are the only possible smoothing ker-nels for scale space analysis. To achieve rotation invariance and a high level of effi-ciency, we have chosen to select key locations at maxima and minima of a difference of Gaussian function applied in scale space.

Histograms of Oriented Gradients for Human Detection

are computed on a dense grid of uniformly spaced cells and they use overlapping local contrast normalizations for im-provedperformance. We make a detailed study of the effects of various implementation choices on detector performance, taking “pedestriandetection” (the detection of mostly visible people in more or less upright poses) as a ...

SURF: Speeded Up Robust Features

3 Fast-Hessian Detector We base our detector on the Hessian matrix because of its good performance in computation time and accuracy. However, rather than using a different measure for selecting the location and the scale (as was done in the Hessian-Laplace detector [11]), we rely on the determinant of the Hessian for both. Given a point

Multi-Similarity Loss With General Pair Weighting for Deep ...

Eq. 1 is computed for optimizing model parameters θ in deep metric learning. In fact, Eq. 1 can be reformulated into a new form for pair weighting through a new function F, whose gradient w.r.t. θ at the t-th iteration is computed exactly the same as Eq. 1. F is formulated as below: F( S,y)= Xm i=1 Xm j=1 ∂L(S,y) ∂Sij ij t. (2) Note that ...

Once binary states have been chosen for the hidden units we produce a “reconstruction” of the training image by setting the state of each pixel to be 1 with probability p(vi = 1 ...
