Time-Efficient Reinforcement Learning with Stochastic Stateful Policies

F Al-Hafez, G Zhao, J Peters, D Tateo - arXiv preprint arXiv:2311.04082, 2023 - arxiv.org
Stateful policies play an important role in reinforcement learning, such as handling partially
observable environments, enhancing robustness, or imposing an inductive bias directly into …

LS-IQ: Implicit reward regularization for inverse reinforcement learning

F Al-Hafez, D Tateo, O Arenz, G Zhao… - arXiv preprint arXiv …, 2023 - arxiv.org
Recent methods for imitation learning directly learn a $Q$-function using an implicit reward
formulation rather than an explicit reward function. However, these methods generally …

LocoMuJoCo: A Comprehensive Imitation Learning Benchmark for Locomotion

F Al-Hafez, G Zhao, J Peters, D Tateo - arXiv preprint arXiv:2311.02496, 2023 - arxiv.org
Imitation Learning (IL) holds great promise for enabling agile locomotion in embodied agents.
However, many existing locomotion benchmarks primarily focus on simplified toy tasks, …

Exciting Action: Investigating Efficient Exploration for Learning Musculoskeletal Humanoid Locomotion

HJ Geiß, F Al-Hafez, A Seyfarth, J Peters… - arXiv preprint arXiv …, 2024 - arxiv.org
Learning a locomotion controller for a musculoskeletal system is challenging due to over-actuation
and high-dimensional action space. While many reinforcement learning methods …

The Role of Domain Randomization in Training Diffusion Policies for Whole-Body Humanoid Control

O Kaidanov, F Al-Hafez, Y Suvari, B Belousov… - arXiv preprint arXiv …, 2024 - arxiv.org
Humanoids have the potential to be the ideal embodiment in environments designed for
humans. Thanks to the structural similarity to the human body, they benefit from rich sources of …

Exciting Action: Investigating Efficient Exploration for Learning Musculoskeletal Humanoid Locomotion

HJ Geiβ, F Al-Hafez, A Seyfarth… - 2024 IEEE-RAS 23rd …, 2024 - ieeexplore.ieee.org
Learning a locomotion controller for a musculoskeletal system is challenging due to over-actuation
and high-dimensional action space. While many reinforcement learning methods …

Redundancy resolution as action bias in policy search for robotic manipulation

F Al-Hafez, JJ Steil - 5th Annual Conference on Robot Learning, 2021 - openreview.net
We propose a novel approach that biases actions during policy search by lifting the concept
of redundancy resolution from multi-DoF robot kinematics to the level of the reward in deep …

Least Squares Inverse Q-Learning

F Al-Hafez, D Tateo, O Arenz, G Zhao… - … European Workshop on … - openreview.net
Recent methods for imitation learning directly learn a $Q$-function using an implicit reward
formulation rather than an explicit reward function. However, these methods generally …

R Crayne, B Harrison, R Khalaf, E Owen, R Karawani… - Citeseer
The Ministry of Finance (MoF) of the Syrian Arab Republic has requested advisory services
from the European Investment Bank (EIB) with a view to expanding medium and long-term …

Religious Minorities in Secular Autocratic Arab Regimes: The Political Discrimination of Christians in Syria

H Anouti - Contemporary Review of the Middle East, 2022 - journals.sagepub.com
The main focus of this article is the political discrimination and/or exclusion of Christian
minorities in Syria, with a particular focus on the era of Hafez al-Assad. It begins by analyzing the …
