Variational Policy Chaining for Lifelong Reinforcement Learning
2019 IEEE 31st International Conference on Tools with Artificial Intelligence (ICTAI), 2019With increasing applications of reinforcement learning in real life problems, it is becoming essential that agents are able to update their knowledge continually. Lifelong learning approaches aim to enable agents to retain the knowledge they learn and to selectively transfer knowledge to new tasks.

Chain Error as a function of Seasonal Variation
SSRN Electronic Journal, 2021In this study, we examine statistically the dependence between Seasonal Variation of consumed values and the ChainErrors of corresponding excellent indices in different subgroups Ak. First, cyclic seasonal variation of values is calculated by simple regression analysis and the ChainError is calculated by the Multi Period Identity Test.

Variation of the alkyl side chain in Δ8-THC
Life Sciences, 1995The synthesis of (2'RS)-2'-methyl-, (3'RS)-, (3'S)-3'-methyl-, and 4'-methyl-delta 8-THC has been carried out, and the pharmacology of all four compounds has been investigated. All four compounds showed typical cannabinoid activity both in vitro and in vivo.

Chain transitivity and variations of the shadowing property
Ergodic Theory and Dynamical Systems, 2014We show that, under the assumption of chain transitivity, the shadowing property is equivalent to the thick shadowing property. We also show that, if ${\mathcal{F}}$ is a family with the Ramsey property, then an arbitrary sequence of points in a chain transitive space can be ${\it\varepsilon}$-shadowed (for any ${\it\varepsilon}$) on a set in ...

Variational theory for Lennard-Jones chains
Molecular Physics, 1995The Helmholtz energy and pressure for Lennard-Jones chains are derived using a variational first-order perturbation theory. The reference system, comprising freely jointed tangent hard-sphere chains is solved in the Percus-Yevick approximation. The optimal diameter of segments in the hard-sphere chain reference is determined by minimizing the free ...

A variational inequality model for supply chain
2011 Second International Conference on Mechanic Automation and Control Engineering, 2011Various types of supply chain model mainly concerns the profit of manufacturers, suppliers and customers. The manufacturers as well as the distributors are assumed to be multicriteria decision-makers and concerned not only with profit maximization but also with risk minimization.

Proximate structural mechanisms for variation in food-chain length
Oikos, 2007Food‐chain length is a central characteristic of ecological communities because of its strong influence on community structure and ecosystem function. While recent studies have started to better clarify the relationship between food‐chain length and environmental gradients such as resource availability and ecosystem size, much less progress has been ...

AN ESTIMATE OF THE VARIATION OF A NORMAL PARAMETER OF A CHAIN ON A PSEUDOCONVEX SURFACE
Mathematics of the USSR-Izvestiya, 1984Summary: On a strictly pseudoconvex hypersurface in a complex manifold, there exists a biholomorphically invariant family of curves called the chains. On each chain one can pick out a certain family of parametrization called the normal parametrizations.
