Recent works reveal that feature or label smoothing lies at the core of Graph Neural Networks (GNNs).

Stochastic gradient methods have been a widespread practice in machine learning.

However, all known theoretical rates are worse than the rate of gradient descent, which synchronizes after every gradient step.

There have been many fruitful results on subspace estimation principal component analysis.
