sofia doesnt work on sparse dataset containing lines in which all features are 0 #14
Description
Hi there.
What steps will reproduce the problem?
./sofia-ml --learner_type pegasos --loop_type stochastic --lambda 0.1
--iterations 10000 --dimensionality 450000 --training_file ../data/m256
--model_out demo/model
What is the expected output?
What do you see instead?
Reading training data from: ../data/final/catted/train/m256
Segmentation fault (core dumped)
What version of the product are you using? On what operating system?
Ubuntu 13.10 64bit
Please provide any additional information below.
I guess it is because my training data (attached) is so sparse that in some
lines all features are zero. Can sofia-ml support such dataset? Thank you!
