TTA: Shuffling the order of concatenated audio segments

First of all, I want to thank @ubenwa for organizing this fascinating competition.

Since it's still relatively quiet here, I'd like to share my first submission that builds on the baseline using a straightforward Test Time Augmentation (TTA):

Create multiple encoding values by shuffling the order of the audio
Average scores from all possible pairs.
This helped me improve the score from the baseline of 0.3075 to 0.2835.

I hope this helps and have fun!

[Notes: your score can different than mine because of the random shuffling and I don't choose the seed]

Congrats on being the first to cross the baseline!

Thanks, @charlesonu ! I'm currently testing several other ideas and will share them all once the competition is over. I really enjoy this competition. It provides a reasonable dataset that suits small-budget competitors like me and serves a meaningful purpose.

Good work @dhoa .
