im currently working on a classification task using language modelling. The first part of the project involved using n-gram language models to classify documents using c5.0. The final part of the proj
Jeff Atwood recently tweeted a link to a CodeReview post where he wanted to know if the community could improve his \"calculating entropy of a string\" code snippet. He explained, \"We\'re calculating
How to find the \"entropy\" with imagemagick, preferably mini_magic, in Ruby? I need this as part of a larger project, finding \"interestingness\" in an image so to crop it.
Suppose M is a set of objects m each having attributes X and Y. Now if X and Y can have only one value for given m (i.e. X,Y are random variables with P(X=x_i|M=m_i), P(Y=y_i|M=m_i)), it\'s possible t
I thought that for making random choices for example for next track in a player or next page in the browser it could be possible to use time as \'natural phenomenon\', for example decent RPNG just can
I\'ve run into some nasty problem with my recorder. 开发者_JAVA百科Some people are still using it with analog tuners, and analog tuners have a tendency to spit out \'snow\' if there is no signal prese
I have an embedded system. What I would like for it to do when it powers up or otherwise resets, is to generate a unique ID, so that on different restarts a different unique ID is generated with high
I was searching for a faster alternative to /dev/urandom when I stumbled across this interesting tidbit:
Let us assume we\'re generating very large (e.g. 128 or 256bit) numbers to serve as keys for a block cipher.
This is a two part question: Part 1 First, dealing with calculating the entropy of a password in PHP.I have been unable to find any code examples that are empirically sound and would really like som
