A New Life Prediction Scheme for Mechanical System with Considering the Mission Profile Switching
Applied Sciences, 2020 The life prediction is crucial to guarantee the reliability and safety of the mechanical system. The current prediction methods predict the life only based on the historical usage pattern of the mechanical system, and do not consider the mission profile ...

Intrinsic Exploration as Multi-Objective RL [PDF]
arXiv, 2020 Intrinsic motivation enables reinforcement learning (RL) agents to explore when rewards are very sparse, where traditional exploration heuristics such as Boltzmann or e-greedy would typically fail. However, intrinsic exploration is generally handled in an ad-hoc manner, where exploration is not treated as a core objective of the learning process; this ...

Exploring Protein Fold Space [PDF]
Biomolecules, 2020 The model of protein folding proposed by Ptitsyn and colleagues involves the accretion of secondary structures around a nucleus. As developed by Efimov, this model also provides a useful way to view the relationships among structures. Although somewhat eclipsed by later databases based on the pairwise comparison of structures, Efimov’s approach ...

Contrasting Exploration in Parameter and Action Space: A Zeroth-Order Optimization Perspective [PDF]
arXiv, 2019 Black-box optimizers that explore in parameter space have often been shown to outperform more sophisticated action space exploration methods developed specifically for the reinforcement learning problem. We examine these black-box methods closely to identify situations in which they are worse than action space exploration methods and those in which ...

Enhanced function-means modeling supporting design space exploration
Artificial intelligence for engineering design, analysis and manufacturing, 2019 One problem in incremental product development is that geometric models are limited in their ability to explore radical alternative design variants. In this publication, a function modeling approach is suggested to increase the amount and variety of ...

Design space exploration in the microthreaded many-core architecture [PDF]
arXiv, 2013 Design space exploration is commonly performed in embedded system, where the architecture is a complicated piece of engineering. With the current trend of many-core systems, design space exploration in general-purpose computers can no longer be avoided.

Dopants Promoting Ferroelectricity in Hafnia: Insights from a comprehensive Chemical Space Exploration [PDF]
, 2017 Although dopants have been extensively employed to promote ferroelectricity in hafnia films, their role in stabilizing the responsible ferroelectric nonequilibrium Pca21 phase is not well understood.

Eurasian Chemico-Technological Journal, 2013 For over past years, interest of leading space agencies (NASA, JAXA, ESA, RSA, etc.) in SHS experiments under microgravity conditions has been increasingly growing. The first SHS experiments during a parabolic flight in Russia and aboard the MIR Space station gave promising results.
