I wrote something similar last year in Java for a school project, and decided to rewrite it in Python this summer for practice. The purpose of the algorithm is to discover internal structure in some set of data points - you supply… K Factor????? 14 Years Ago by confusedndazed Hello all, I'm very confused on this K factor stuff.....I understand that...1*2*…*k indicates the product of consecutive numbers and therefore: 1*2*…*5 is actually 1*2*3*4*5 = 120 But I'm not sure how to write that as a code. I have the following information: /* pseudocode for Binomial Coefficients */ int binomial(int… K Means Clustering Algorithm 14 Years Ago by sathya8819 Hi, I am trying to implement the K Means Clustering Algorithm for Image Segmentation. The logic behind K Means is : 1. Place K points into the space represented by the objects that are being clustered. These points represent initial group centroids. 2. Assign each object to the group that has the closest centroid. 3. When all … Re: K-means clustering 14 Years Ago by dgg32 Nice man. A barebone k-means imple. Learn a lot from you. Some suggestion: Make a second iteration, so that we can try different k values and take the has the smallest within-cluster sum of squares. Or, output the within-cluster sum of squares in the end. So the user may run your code several times or put it to parallel computering with … Re: K-means clustering 13 Years Ago by nicegiving Very good program but I think your code may have a bug, that is one of the clusters may be empty in the end, and there will be an exception in line 54, the exception will be like: "ZeroDivisionError: float division" because self.points is "[]". I created an image to illustrate the problem:[URL="http://systemsbiozju.org/… Re: K Factor????? 14 Years Ago by mrnutty no. the k is passed in from main. So k can be any number.

K&R with Visual C++.net version 2003 16 Years Ago by fcleme I am trying to relearn C by going through the K&R exercises (I have the first, non-ANSI, edition...that's how long it's been since I last programmed in C under Unix as a software engineer).

I got some advice from some guy, but I am a newbie to wxpython so I don't know how to follow it and it will take a long time until I will become capable to do it. Since it may be much easier for you to do it, … Re: K&R with Visual C++.net version 2003 16 Years Ago by Salem It would be better IMO to actually learn ANSI-C. K&R C is strictly historical or for old code requiring long term maintenance. Re: K&R with Visual C++.net version 2003 16 Years Ago by fcleme Thanks for your prompt suggestions. I am definitely going to buy the ANSI-C version of the K&R book. But I expect to have the same problem of trying to run the exercises under the IDE instead of Unix. I saw in another post from Narue that you can tell the compiler to compile C code rather than C++ code. That would be a good start. Thanks … Re: K&R with Visual C++.net version 2003 16 Years Ago by Ancient Dragon >>can tell the compiler to compile C code rather than C++ code. Yes, just name the source file with *.c extension instead of *.cpp and the IDE will know how to compile it. >>I am definitely going to buy the ANSI-C version of the K&R book Get a different book because even that one is out-of-date.

I would suggest that you print "grades" so you at least know what it contains. Re: (m-k)perfect number generator 11 Years Ago by Gonbe I find your code pretty difficult to read. Why don't you divide problems into a smaller problems by using functions? I don't really know the theory behind perfect numbers that well but on a quick attempt I would go for something like this, which is quite different and (in my opinion) easier to read.
