# Re: [hpx-users] Continuous regressions instead of multi-class classification

```Hi Gabriel,

Sorry for my late responses, as I am not at university anymore and I am
working at Oracle so I am kind of busy here with my ongoing projects. But I
would like to help you understand the concepts as much as possible. However
you could also count on Patrick and also Dr. Kaiser if you found me not
easy to find ;)
even different amounts of candidates. But they should be chosen wisely. You
can do tests on your chosen candidates to see how your learning model acts
using them. If random candidates are chosen, your model will not result as
expected!
You are also free to choose different learning model.
However our main focus in this project is to use online machine learning
methods. Such that it will not required to collect offline data anymore. So
the system learns as it receives new data through time. But for the first
phase of this project please continue working and studying different
learning models and may trying with different candidates.
If it’s possible and you have time, you can also start writing your
proposal, so we could finalize it together. It’s the best way to clarify
the steps of this project.```

Thanks,
Zahra
