Hi,
How do we change (that is reduce the speed of the incoming stream data) the Stream Speed in MOA GUI??

What do you mean by the speed of the incoming stream?

Cheers, Albert

Hi,

java -cp moa.jar -javaagent:sizeofag.jar moa.DoTask \
"MeasureStreamSpeed -s generators.WaveformGenerator \
-g 100000"
this command we use to Measures the speed of a stream(as given in the MOA Manual), similarly do we have any command to increase or decrease the stream speed??

Hi,
I have a dataset with 2400000 instances in .arff format with 2 attributes in numeric which contains values like
23.0,11007.0
23.0,110092.0
23.0,110042.0
23.0,200058.0
23.0,110094.0
23.0,200052.0
 when i run it in MOA GUI for Clustering using clustream algorithm, in the Visualization tab, i get error in the terminal as follows

Hi,

The stream speed can just be measured but not changed. The stream speed depends on your computer specifications. I guess you can create your own StreamFilter (in Java) to slow down the stream but not to increase its speed.

Best,

Christophe

Hi all,
 In MOA we have command to run classification from Command Line Prompt as follows

java -cp moa.jar -javaagent:sizeofag.jar moa.DoTask \

LearnModel -l trees.HoeffdingTree \
-s generators.WaveformGenerator -m 1000000 -O model1.moa

(which is given in the moa manual)

similarly do we have any command to run clustering from the Command Line Prompt without using the GUI interface??
