Electrical grids are large-sized complex systems that require strong computing power for monitoring and analysis.

Robust Meta-Representation Learning via Global Label Inference and Classification

1 code implementation22 Dec 2022 Ruohan Wang, Isak Falk, Massimiliano Pontil, Carlo Ciliberto

Empirically, MeLa outperforms existing methods across a diverse range of benchmarks, in particular under a more challenging setting where the number of training tasks is limited and labels are task-specific.

The Role of Global Labels in Few-Shot Classification and How to Infer Them

no code implementations NeurIPS 2021 Ruohan Wang, Massimiliano Pontil, Carlo Ciliberto

Few-shot learning is a central problem in meta-learning, where learners must quickly adapt to new tasks given limited training data.

Structured Prediction for Conditional Meta-Learning

1 code implementation NeurIPS 2020 Ruohan Wang, Yiannis Demiris, Carlo Ciliberto

We derive task-adaptive structured meta-learning (TASML), a principled framework that yields task-specific objective functions by weighing meta-training data on target tasks.

Support-weighted Adversarial Imitation Learning

no code implementations20 Feb 2020 Ruohan Wang, Carlo Ciliberto, Pierluigi Amadori, Yiannis Demiris

To address the challenges, we propose Support-weighted Adversarial Imitation Learning (SAIL), a general framework that extends a given AIL algorithm with information derived from support estimation of the expert policies.

Support-guided Adversarial Imitation Learning

no code implementations25 Sep 2019 Ruohan Wang, Carlo Ciliberto, Pierluigi Amadori, Yiannis Demiris

We propose Support-guided Adversarial Imitation Learning (SAIL), a generic imitation learning framework that unifies support estimation of the expert policy with the family of Adversarial Imitation Learning (AIL) algorithms.

MAGAN: Margin Adaptation for Generative Adversarial Networks

1 code implementation12 Apr 2017 Ruohan Wang, Antoine Cully, Hyung Jin Chang, Yiannis Demiris

We propose the Margin Adaptation for Generative Adversarial Networks (MAGANs) algorithm, a novel training procedure for GANs to improve stability and performance by using an adaptive hinge loss function.
