View Full Version : SVM Data

12-06-2007, 03:35 AM

I would like to intend to use SVM algorithm using Weka on my input file.

However, I wonder what type of input file pattern is allowed. Currently, I am having columns with class label rather than the usual horizontal rows with class labels.

Do SVM allow these data?

Hi there,

Data will need to be in Weka's ARFF format, which is row-based (one row per training example). See here for details:

Hi Mark,

Thanks for your reply. I just wondered given the fact I have over 600 data attributes of numbers; with class label in the end, would I able to use SVM using Weka to produce some information?

I did try to use weather.arff and play around with SVM but I have difficulty in adapting my problem area in this.

For example;-

My scenario is having 1000 different groups which shares further 600 unique data attributes for each group respectively.


Group Value
T1 2,5,8,9,3,.................(up to 600 number of attributes)
T2 .................

The group T1,T2..........(till 1000)

so I was wondering what would be my attribute look like? Would it be something like
@attribute TT{T1,T2.......T1000}
@attribute ?????
@attribute Get{Yes,No}

but how can I represent the vector of 600 numbers which each T1,T2......T1000 have?

Basically I would like to study the relationship of the 600 numbers which each element in TT have to predict the Get {Yes,No}

I am kind of new to Weka and so far the example I have seen is not on numeric but more on nominal such as weather.arff.

Please advise.
