search for: positv

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

...ns: 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 about it, when sext to results a positve/negative value? Thank for any advice Quang

> 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 v...

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<...

...mbers in the row, count them instead and insert a minus symbol before (e..g -4, to denote that this was determined on negative numbers). If the number of positive and negative numbers in a given row are equal, then return a zero for that row. Finally, if all values in a row are zero (i.e. neither positve or negative) then return -99999. I've had a go at this myself for some considerable time, trying the use of an 'apply' (by rows) function, but seem unable to successfully achieve the above. Any help would be very gratefully received. Many thanks, Steve ______________...

...et I construct a set of (d1(x1,y1), ..., dn(xn,yn), x_class != y_class) rows bound together as a data frame (actually I construct it by columns), and then the obvious thing to try was glm(different.class ~ ., family = binomial(), data = distance.frame) The thing is that this gives me both positve and negative coefficients, whereas the linear combination is only guaranteed to be a metric if the coefficients are all non-negative. There are four fairly obvious ways to deal with that: (1) just force the negative coefficients to 0 and hope. This turns out to work rather well, but still......

Types like i16 aren't inherently signed or unsigned. 1111 1111 1111 1111 is both 65535 and -1; the interpretation depends on how the result is used. -Eli

This appears to be correct, CommonWorkgroup is MSHOME. ** Commands smbclient LinuxServer/alistedshare and smbclient XPHomeClient/alistedshare both allow access to the referent shares, and put, get, and rm all work.

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 ?
