Unlocking Tuning-free Generalization: Minimizing the PAC-Bayes Bound with Trainable Priors

no code implementations30 May 2023 Xitong Zhang, Avrajit Ghosh, Guangliang Liu, Rongrong Wang

It is widely recognized that the generalization ability of neural networks can be greatly enhanced through carefully designing the training procedure.

Implicit regularization in Heavy-ball momentum accelerated stochastic gradient descent

no code implementations2 Feb 2023 Avrajit Ghosh, He Lyu, Xitong Zhang, Rongrong Wang

It is well known that the finite step-size ($h$) in Gradient Descent (GD) implicitly regularizes solutions to flatter minima.

Bilevel learning of l1-regularizers with closed-form gradients(BLORC)

no code implementations21 Nov 2021 Avrajit Ghosh, Michael T. McCann, Saiprasad Ravishankar

We present a method for supervised learning of sparsity-promoting regularizers, a key ingredient in many modern signal reconstruction problems.
