Training Data Format and Class Label for kmeans

[GoogleCodeExporter]

Hi,

I have changed my training data into sparse data format you mentioned.
./sofia-kmeans --k 1000 --init_type random --opt_type batch_kmeans --iterations 
1000 --objective_after_init --training_file demo/SMLFAutoTrain1s512val.txt 
--model_out demo/CSMLFAutoTrain1s512val.txt
However, I am getting the following errors:
Reading data from: demo/SMLFAutoTrain1s512val.txt
Error reading file demo/SMLFAutoTrain1s512val.txt
I opened your demo.train, I saw that you have square box at the end of every 
vector. How can I changed my data format to yours since the square box at the 
end may not be the only one? I tried to fetch your demo.train file in matlab, 
and it doesn't let me do that either.

For the example of kmeans:
> ./sofia-kmeans --k 5 --init_type random --opt_type mini_batch_kmeans 
--mini_batch_size 100 --iterations 500 --objective_after_init 
--objective_after_training --training_file demo/demo.train --model_out 
demo/clusters.txt
the above command will return the five centroid location, right?
In this case, since only producing the 5 cluster center location, the class 
label in the training data (demo.train) can be assigned with any values, right? 
Of course, I chose, say, all 1 among these values: 1,0,-1.

I look forward to your clarification. 

Thank you,


Fred
