Predicting Tags #3

Closed Alex-A14 closed 4 years ago

Alex-A14 commented 4 years ago

This is cool! I took a quick look at the HCI page. What kind of tags would you be looking to predict? Something binary (e.g. distracting/not distracting, accurate/inaccurate), or a range of more descriptive tags?

Do you know what intervals you would use for EEG? i.e. Are you looking at the signal near a particular event or across stimulus exposure?

Thanks! We were thinking of predicting valence and arousal (for the datasets where this is available). Do you already know what you'll be predicting for your project (e.g. which piece was played)?

As for the EEG, it's a difficult question, especially when the stimuli durations are different! We thought we'd look at the signal across stimulus exposure, or e.g. the first X seconds when they're different lengths.

Update: we ended up not predicting valence and arousal and rather predicting "target emotions". Thank you for bringing up this issue, it wasn't straightforward!
