Hi Ryan, - How does CloudRF calculate the weights file? (p-values) - Assume we have a weight file (according to p-values), how can we grow cloudRF using these weights?
My data set is in this case: https://github.com/ryanbressler/CloudForest#data-with-lots-of-noisy-uninformative-high-cardinality-features I have a weight file based on p-values, how can I type a command to grow trees in CloudRF using this weight...
How can I grow a cloudRF with libsvm file? (I don't know which a target to declare). e.g: ~/cloudRF/growforest -train usps.libsvm -rfpred usps.sf -target ??? -nTrees 1000 where usps.libsvm is...
I received some errors as below: ~/cloudRF/growforest -train usps -rfpred usps.sf -target 0 -nTrees 500 Threads : 1 nTrees : 500 Loading data from: usps panic: runtime error: index out...
Great! It is running. You should write some comments abt this for CloudRF's users :) Thanks Ryan!
ryanbressler commented "-target 0 should do it since the target is in the first column and their aren't column names" How does CloudRF recognite the data type of the target...
OK, thanks! That is a good way. It also can read spare libsvm format file, right? i.e. Xi and Yi represent such as col:value e.g data with 100 features: 3...
In LIBSVM file containing lots of records (e.g 60,000,000), how can I build trees in couldRF? I try setting a portion of total records using "nSamples=0.1" option, that means cloudRF...
I mean RF struggles to build trees from large samples size because of a tree size is large. In cloudRF, RF can grow from a portion of total records. My...
