Some of the tricks, often not mentioned in papers, end up playing a crucial role. Contrastive Divergence using one step of Gibbs sampling:


Stochastic Maximum Likelihood method using one step of Gibbs sampling:


It is trickier to analyse the convergence of CD, but the theory still says a lot about the tricks (e.g. momentum, constant learning rates) used to make CD working in practice.

There are many ways to assess the performance of an RBM, these include log-likelihood, train misclassification error, test misclassification error, reconstruction error, and samples generated from the model.

While ideally one would choose log-likelihood as well as test error for assessing the performance of training an RBM for classification.

It is expected that more hidden units will improve classification performance, but then it becomes prohibitive to run many experiments; in general the model is computationally impractical when the number of hidden units is too large.

Terrorism is killing other people for attention: its a drive-by

2001-09-23 00:59:11 by MarkfromCalifornia

I got an opinion:
Without the mouthpiece of publicity that our present news coverage practice all too often provides, terrorism would simply be the killing of other human beings for nothing other than attention. An act possibly too disgusting even for would be terrorists who often mistake notoriety for glamour or fame. Perhaps News should have more financial autonomy, regardless, news should be coupled with the responsibility that trust has endowed it with, because, people trust and follow the news in more ways than one. News should be differentiated from spectacle. And after a point, News does become spectacle. News should realize that it is possible to cover even incidents of terrorism without giving it undue coverage. News should not feel the need to compete with other forms of...

I suspect 'relativity' is at the fundamental
reasoning related to values thereof.
When one has sufficiently acquired their daily needs
of nourishment and shelter for the support of their physical existence
then one is at liberty to entertain them self
with collecting other objects which physically exist
within this universe.
Rarity appears to become the gauge of value
when given objects are used as trade for other objects.
And thereat,
paper currency with printed number symbols upon it
takes very little energy to produce
at least in comparison to the mining of silver and gold
which are more energy intense.
