Curious Meta-Controller alternates between model-based and model-free control to improve sample efficiency.

problem Combining the benefits of model-based and model-free control to enhance sample efficiency.
method Adaptive alternation between model-based and model-free control using curiosity feedback.
result Significantly improved sample efficiency and near-optimal performance on robotic tasks.

This paper improves robot grasping by integrating meta-control and latent-space imagination.

problem Dual-system approaches fail to consider the reliability of the learned model when making multiple-step predictions.
method A meta-controller arbitrates between model-based and model-free decisions based on local reliability, encouraging actions that improve the model and generating imagined experiences for additional training.
result Our approach learns near-optimal grasping policies in dense- and sparse-reward environments, outperforming baseline and state-of-the-art methods.

We introduce a new function-preserving transformation for efficient neural architecture search. This network transformation allows reusing previously trained networks and existing successful architectures that improves sample efficiency. We aim to address the limitation of current network transformation operations that…

RG-TTA adapts neural forecasters to streaming time series shifts by modulating adaptation intensity.

problem Adapting neural forecasters to distribution shifts in streaming time series data.
method RG-TTA uses a meta-controller that continuously modulates adaptation intensity based on distributional similarity.
result RG-TTA achieves the lowest MSE in 156 of 224 seed-averaged experiments, reducing MSE by 5.7% vs TTA.

A core aspect of human intelligence is the ability to learn new tasks quickly and switch between them flexibly. Here, we describe a modular continual reinforcement learning paradigm inspired by these abilities. We first introduce a visual interaction environment that allows many types of tasks to be unified in a single…

CNAS optimizes neural architectures for class-incremental learning.

problem Capacity saturation in static neural architectures for class-incremental learning.
method CNAS uses reinforcement learning and network transformations to adaptively select architectures.
result CNAS outperforms static architectures and is more efficient.

GeNAS uses genetic algorithms to automatically assess human sperm morphology.

problem Manual sperm morphology analysis is inexact, subjective, and hard to teach.
method Genetic Neural Architecture Search (GeNAS) for automatic SMA.
result GeNAS achieved state-of-the-art results in sperm morphology detection.
