How fast is PhysX on GPU compared to physics engines on CPU? -


i have application written use bullet physics engine. running on intel i7 2600k cpu 8 cores. application has process millions of chunks of physics work, each of can done independently. runs 8 processes, each process working through quota of total independently. in summary, work has lot of easy parallelism.

assuming can acquire best nvidia consumer graphics card (say titan), ballpark improvement in physics engine performance can see switching bullet on cpu physx on gpu? is, approximately how faster application run if rewritten physx?

i found few papers compare result quality between bullet , physx, not find performance comparison.

i found this, it's not comparison against specific cpu physics engine 1 hopes comparing like , running physx on cpu.

so it's rather unspecific , faq makers of physx take pinch of salt.

from here:

running physx on mid-to-high-end geforce gpu enable 10-20 times more effects , visual fidelity physics running on high-end cpu.

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
