How to compute the harmonic mean

[jingzhengli]

Thanhs for sharing the code. After I obtain the results of base classes and novel classes, how to compute the harmonic mean?

Hi @jingzhengli,

Thanks for showing interest in our work.

The harmonic mean is calculated as, $(2 \times Base{acc} \times Novel{acc}) / (Base{acc} + Novel{acc})$

Thank you.

Hi, Thanks for sharing the nice work! @jingzhengli @hanoonaR

I have a question about calculating the harmonic mean.

Base_acc and Nov_acc are the best accuracy in three runs or average in three runs?

Thank you.

Hi @dneirfi ,

Please note that we report the average over three runs both in Base_acc and Novel_acc, following the general few-shot experimental settings. Hope it is clear. Thank you.
