Does anyone know of a table somewhere for relative frequencies of not just letters, but also punctuation/special characters? I need to use the table to set the letter frequencies for my Huffman code key generation algorithm, but in over half an hour googling I have been unable to find anything that gives a comparison between letters and special characters (I have found letter tables, and I even found one comparing just special characters, but nothing to compare them with each other).

I need a dataset for my future project based on image processing, hand recognition. I need a minimum of 5 hand position and orientation and a minumim of 200 images per set.
I want to know if there are websites where I can find a great variety of datasets.
I recommend you to search here: http://homepages.inf.ed.ac.uk/rbf/CVonline/Imagedbase.htm#gesture.
I needed this for a project too and I found a lot of variations here. It also depends on what kind of gestures you are looking for, but I think you will find here what you need.

I am working on a project that makes use of Neo4j.
Cypher is used for queries, and Prolog for reasoning (after translation from Neo4j model).
Is there any alternative to Prolog for reasoning that does not need a translation step from Neo4j?
The closest thing I know is: https://github.com/lambdazen/pixy/wiki but I'm, not sure about its current status.

There is a cute series of four blog posts arguing that memory access should not be considered constant time, but should instead incorporate a square root factor. I cannot seem to find it now however. Anyone got the link?

I have a DataSet of words and texts and I want to make clusters (by K-means )or any other unsupervised/supervised learning method to distinguish words for example , the word 'John' will be classified as a name(and will be clustered with other person names) , 'brazil' as a place and etc...
Is there a model that I can use to solve the problem.
I have Heard of N-grams but I dont know how to plot the Ngrams probability on a x,y plot or such
P.S if you have any examples that will be wonderful
How about word2vec and embeddings?
