Bias Correction in Adam
easy
Why does Adam include bias correction for the moment estimates?
A
The moment estimates accumulate numerical errors over many steps — bias correction resets them periodically to prevent drift
B
The moment estimates are initialized at zero, so early estimates are biased toward zero — bias correction rescales them to compensate
C
The moment estimates are computed on mini-batches — bias correction adjusts for the difference in batch size versus full-dataset gradients
D
The moment estimates use exponential decay — bias correction converts them from exponential to linear averages for stability
