Great, how about create a skype group?

> WRT to scalar, I think it may be a good idea, but I'm yet to see an exact use-case. Do we already have any algorithm that requires it? Not...

> I have no opinion on the scalar/vector issue. I'll let you guys decide. Seems like it's working fine as it is right now. OK, then Iet's focus on scalar...

@sjwhitworth It could be just simple manupulations. Just like `string` version's matrix. The idea raised in `ParseCSV`. I'd like to be able to parse CSV with multiple labels.

Oh... that's really a problem... Basically, we can train each label separately. Of course there are some algorithms need to consider all labels at the same time, but I think...

OK! Let's GO! Summary: - Use `biogo.matrix` to replace `mat64` - Metrics package should always return scalar - Introduce `Label` struct, I'll implement this one - Put all external dependencies...

@Sentimentron Wow, that's really awesome. I think your `Instance` is basically the `Label` I want to implement. I have, however, some concerns: - Using `Instance` for labels is good, but...

@hpxro7 I have no idea about how much work need to be done if we choose to rollback to mat64. On the other hand, would you think it is possible...

OK, I think switch back to gonum is an acceptable choice. If all of you guys think it is a good idea, then let's do it. I can work on...

遇到了同個問題，請問後來有找到任何解法嗎？
