[chain2] configuration façade APIs

2012-07-21 Thread Simone Tripodi
Hi all guys, Elijah and and I had a chat and we thought that, since chain2 hasn't released yet, we are still in time to define a façade API for textual configurations and rename the current XML configuration module to xml-configuration (and adapt it to new API) - new formats such as YAML and JSON

2012-07-21 Thread Ted Dunning
Synchronization in low level code is generally really bad. This is the whole point of why Vector was essentially thrown away in Java collections in favor of ArrayList. Better to synchronize in the caller who knows about the multi-threading. Or simply build a synchronized wrapper in an inner clas

The easy way to get much of this benefit is to simply use multi-threaded versions of Atlas via jblas. Probably not viable given the no dependency posture of commons math. On Sat, Jul 21, 2012 at 6:17 AM, Gilles Sadowski < gil...@harfang.homelinux.org> wrote: > Hi. > > My previous post (with subj

[BCEL] Faq update?

2012-07-21 Thread Elijah Zupancic
Hi there, I was trying to figure out if BCEL supports java 1.7 yesterday. After doing a few experiments, it appears that it somewhat supports it as it is used in findbugs until I use 1.7 features. I think that we should update the FAQ for the project. Any one here know more about this than me? Th

Hi Phil I took a closer look at the Spearmans correlation and note that it uses an underlying PearsonsCorrelation object to do the actual work of calculating the correlation value after ranking. Do I have to do the same for Kendalls Tau? I.e. Do I need to have two classes 1)KendallsTauCorrelatio
