Hello, this question is a bit out of the blue. I am a big R fan and user and in my new job I do some decision modeling (mostly health economics). For that decision trees are often used (I guess the most classic example is the investment decision A, B, and C with different probabilities, what is the expected payoff). We use a specialized software called TreeAge that some might know. The basic

A client has inquired about producing a decision tree from data which could include: - ID of brand purchased - Importance ratings (1-10 scale) for a number of relevant attributes (price, strength, recommended by a friend, etc.) In other words, a rating of how important each attribute is in the decision as to which brand to purchase. I've just run a test decision tree using the closest thing

Ok is there a way to do it with decision tree? I just need to make the decision rules. Perhaps I can pick one of the trees used with Random Forrest. I am somewhat familiar already with Random Forrest with respective to bagging and feature sampling and getting the mode from the leaf nodes and it being an ensemble technique of many trees. I am just working from the perspective that I need

Hal, Thank you for finding interest in our work!

This patch: * adds a C-based security policy translation tool to Xen (secpol_xml2bin) and removes the current Java security policy translator (Java dependencies). The C-based tool integrates into the Xen source tree build and install (using gnome libxml2 for XML parsing). See install.txt. * introduces security labels and related tools. Users can now use semantic-rich label names to put

This is a first step towards to full iterative compilation framework for Clang/LLVM. The attached patch is work in progress and the idea of sending it to the list earlier rather than later is to open up a discussion on iterative compilation in Clang/LLVM. All comments are welcome, especially those related to integration of the framework into Clang/LLVM. Current compilers have pipeline structure

Hi Everyone, Numerous people have been bringing up challenges with consensus driven decision making in the LLVM community. After considering this and seeing the frustrations it is causing many people, I think we should make a formal process change to help improve decision making going forward. Here is the outline of the draft proposal

Hi Experts, I am new to R, using decision tree model for getting segmentation rules. A) Using behavioural data (attributes defining customer behaviour, ( example balances, number of accounts etc.) 1. Clustering: Cluster behavioural data to suitable number of clusters 2. Decision Tree: Using rpart classification tree for generating rules for segmentation using cluster number(cluster id) as target

Hi I'm trying to get the top decision rules from a decision tree. Eventually I will like to do this with R and Random Forrest. There has to be a way to output the decsion rules of each leaf node in an easily readable way. I am looking at the randomforrest and rpart packages and I dont see anything yet.

Hi, I am somewhat new to R so this question may be foolish, but is it possible to add decision trees into a list, array or vector in R? I am trying to build a collection (ensemble) of decision trees. Every time a new instance arrive I need to get the prediction of each decision tree. I have tried to add a decision tree into a variable but without luck. Is a special package needed perhaps? This

Radovan, Thanks for posting this! I would really like to have this kind of functionality available.

Hi Radovan, I am also interested in the iterative compilation in LLVM, and had implemented a simple iterative compilation driver. I guess you do not need to embedded the pointer to ModuleDecisionTreeProxies into the core classes of llvm, i.e. the PassManager class and the Function class. Instead, you could: 1. Implement a special pass manager that runs a set of passes iteratively. Implementing

Dear mailinglist members, I have the following problem: I run a decision tree using the rpart function and, afterwords, I try to find to which leaf node a new register (not used to build the decision tree) belongs to. I will try to explain better: rpart.tree <- rpart(target.value ~., data) leaf.node <- new.function(rpart.tree, new.register) The new register has all the explanatory values

Have anybody used Decision Tree in Python or C++? (or written their own decision tree implementation in Python or C++)? My goal is to run decision tree on 8 million obs as training set and score 7 million in test set. I am testing 'rpart' package on a 64-bit-Linux + 64-bit-R environment. But it seems that rpart is either not stable or running out of memory very quickly. (Is it

Nope. Random forests are not decision trees -- they are ensembles (forests) of trees. You need to go back and read up on them so you understand how they work. The Hastie/Tibshirani/Friedman "The Elements of Statistical Learning" has a nice explanation, but I'm sure there are lots of good web resources, too. Cheers, Bert Bert Gunter "The trouble with having an open mind is

Hi all, Below is a proposal for refining the way we communicate between the ThinLTO link step (the combined indexing step) and the backend processes that do the actual importing and other summary-based optimizations in a distributed backend process. Mehdi, let me know if this addresses your concerns. Peter, PTAL from the standpoint of any summary extensions needed for CFI and make sure they can
