Can someone suggest a classifier for non iid data with error bound?

I am looking for a classifier that will give us an error bound (expected performance) on test data. Also, we should not assume the data is independent and identically distributed) or features have...

Let s_i be Rademacher variables (+/-1 with P=1/2) and x_i real. I find numerically that E[ | sum_i s_i * x_i |] = max{ | x_i | }. True?

Khinchine's inequality gives me an upper bound on the r.h.s. of (sum_i x_i^2)^(1/2) but I found nothing about the stronger equality being true though the numerics suggest it.

Can you recommend any research paper comparing ensembles of neural networks with deep learning on UCI datasets?

I am wondering whether deep learning can give better results than boosted models.

How can you calculate the description length of a random forest?

In research, I have a set of random forests which are generated from a given set of datasets. Now I would like to calculate the description size (based on the MDL method proposed by Quinlan) of...

What is the purpose of partial correlation..?

I have four variables which are correlated to each other, thus should I do partial correlation to find correlation between any two random variables with other two control variables?

How can we calculate the shannon entropy for a dataset which we want to train a machine with?

Suppose we deal with a dataset with different kind of attributes (numeric and nominal) and binary class. How can we find a unique number as the shannon entropy of this dataset (as a presentation...

Which criterion is better in order to define Random Forest size?

Since random forest includes a bunch of random decision trees, it is not clear when we say forest size, it can be : 1) number of bits it takes 2) number of decision trees included in forest 3)...
