Manifold-Aligned Guided Integrated Gradients for Reliable Feature Attribution

ICML 2026poster

Feature attribution is central to diagnosing and trusting deep neural networks, and Integrated Gradients (IG) is widely used due to its axiomatic properties. However, IG can yield unreliable explanations when the integration path between a baseline and the input passes through regions with noisy gra…

Adaptive and Explainable Deployment of Navigation Skills via Hierarchical Deep Reinforcement Learning

ICRA 2023poster

For robotic vehicles to navigate robustly and safely in unseen environments, it is crucial to decide the most suitable navigation policy. However, most existing deep reinforcement learning based navigation policies are trained with a hand-engineered curriculum and reward function which are difficult…

Refining Diffusion Planner for Reliable Behavior Synthesis by Automatic Detection of Infeasible Plans

NeurIPS 2023poster

Diffusion-based planning has shown promising results in long-horizon, sparse-reward tasks by training trajectory diffusion models and conditioning the sampled trajectories using auxiliary guidance functions. However, due to their nature as generative models, diffusion models are not guaranteed to ge…

Variational Curriculum Reinforcement Learning for Unsupervised Discovery of Skills

ICML 2023poster

Mutual information-based reinforcement learning (RL) has been proposed as a promising framework for retrieving complex skills autonomously without a task-oriented reward function through mutual information (MI) maximization or variational empowerment. However, learning complex skills is still challe…

Deep Reinforcement Learning in Continuous Action Spaces: a Case Study in the Game of Simulated Curling

ICML 2018oral

Many real-world applications of reinforcement learning require an agent to select optimal actions from continuous spaces. Recently, deep neural networks have successfully been applied to games with discrete actions spaces. However, deep neural networks for discrete actions are not suitable for devis…
