search for: positves

Dear R-users, I have a set of 12000 image samples. I can divide this set into two categories: training and testing. I need to classify the test set into a two qualitative outputs: true or false for some characteristic. To do the classification I'm using the packages SVM in e1071 library and LDA in the MASS library. However, I'm with a great number of FALSE POSITIVE CASES in both

Hi, I have a question about the "sext..to" instruction. In the document, I found two examples: %x = sext i8 -1 to i16 It means: i8 -1 = 1111 1111 --> 1111 1111 1111 1111 = i16 how can it determinate, that the i16 value %x positive is (65535)? And the second example: %y = sext i1 true to i32 1 --> 1111 1111 1111 1111 1111 1111 1111 1111 In this example, %y is -1 I'm not sure

> I'm not sure about it, when sext to results a positve/negative value? sext does signed-extension, zext does unsigned-extension. This means that zext always extends by zero bits, while with sext the additional bits are all copies of the top bit of the original value. So with sext, if it was negative in the original type when considered as a signed value, then it will be negative in the

Hi all..RCounters! I´m working with standarized time series, and i need make a counter of consecutives positves numbers to make a cumulative experimental funtion. I have x: the time series (0,1) and y: my counter, i have this for step. What is wrong?.. any can help me please! x<-rbinom(15,1,.3) y<-NULL;s<-0 for (i in 1: length (x)) {if (x[i]>0) {s<-s+x[i] s=0} else y<-c...

Hello Everyone, I have what I think is a complex text parsing task. I've provided some sample data below. There's a relatively simple version of the coding that needs to be done and a more complex version. If someone could help me out with either version, I'd greatly appreciate it. Here are my sample data. haveData <- structure(list(profile_key = structure(c(1L, 1L, 2L, 2L, 2L,

Hello All, Can anyone tell help me understand why the function below doesn't work and how I can fix it? Below are some sample data, some code that works on individual rows of the data, and my attempt to translate that code into a function. My hope is to get the function working and then to apply it to the larger data frame using ddply() from the plyr package or possibly some other approach.

Dear all, I have a data frame of 6 columns and ~60000 rows which I hope to perform the following calculation on. For each row, I wish to determine whether there are a greater number of positive or negative numbers. Then, if there are more positive numbers in the row, count how many occur - but if there are more negative numbers in the row, count them instead and insert a minus symbol before

I am trying to automatically construct a distance function from a training set in order to use it to cluster another data set. The variables are nominal. One variable is a "class" variable having two values; it is kept separate from the others. I have a method which constructs a distance matrix for the levels of a nominal variable in the context of the other variables. I want to

Hi all. I want to use two servers with dovecot using a common file system with drbd. So I have several questions. If one server write a mail to th file system he will use his name as part of the mail identification. the second server will use his own name. Each server will generate it own mail numbers . When an imap or pop user will consult the mails i shoul be confusion. Am I correct. is there

I was wondering if anyone here has or knows how to implement ttysnoop w/ssh ?
