Trust the Model When It Is Confident: Masked Model-based Actor-Critic [PDF]
arXiv, 2020 It is a popular belief that model-based Reinforcement Learning (RL) is more sample efficient than model-free RL, but in practice, it is not always true due to overweighed model errors. In complex and noisy settings, model-based RL tends to have trouble using the model if it does not know when to trust the model.

A thermal improvement technique for phase windings of electrical machines [PDF]
, 2012 In electrical machines, a higher torque/force density can usually be achieved by increasing the current density in the windings. However, the resulting increase in copper losses leads to higher temperatures in the coils, especially in the centre of the ...

The Anatomical Record, EarlyView.Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Batteries &Supercaps, EarlyView.A model for blend electrodes is developed, parameterized, and validated using experimental data from a SiOx/Gr electrode. The model provides information about local states, such as the degree of lithiation or material‐specific C‐rates, distinguishing between the two active materials.
