Hi there 👋

About Me

I’m an AI Research Engineer from South Korea. I truly enjoy challenging and improving myself by learning new skills on a daily basis in order to be a full stack AI engineer, covering from formulating the problem to conducting research to deploying models with a focus on data-centric mindset.

tensorflow's Issues

how to deal distance_weight? d1(x) and d2(x)

The separation border is computed using morphological operations. The
weight map is then computed as
w(x) = wc(x) + w0 · exp −(d1(x) + d2(x))2
2σ2 ! (2)
where wc : Ω ! R is the weight map to balance the class frequencies, d1 : Ω ! R
denotes the distance to the border of the nearest cell and d2 : Ω ! R the distance
to the border of the second nearest cell. In our experiments we set w0 = 10 and
σ ≈ 5 pixels.

Thank you very much for providing UNET code. The bce_dice_coefficients loss function mentioned above. But I don't understand how it can solve the problem of category imbalance.
