This paper proposes an effective multi-objective differential evolution algorithm (MDES) to solve a permutation flow shop scheduling problem (PFSSP) with modified Dejong's learning effect. The proposed algorithm combines the basic differential evolution (DE) with local search and borrows the selection operator from NSGA-II to improve the general performance.  First the problem is encoded with a...

The phenomenon of how tests influence teaching and learning is commonly described as “wash back” in language instruction.  Literature indicates that wash back effect is a complex concept that becomes even more complicated under different interpretations of the wash back phenomenon in teaching and learning. In the present study, some definitions of wash back and its two major types were introduc...

Automatic screening of Age-related Macular Degeneration (AMD) is important for both patients and ophthalmologists. The major sign of contracting AMD at the early stage is the appearance of drusen, which are the accumulation of extracellular material and appear as yellow-white spots on the retina. In this paper, we propose an effective approach for drusen segmentation towards AMD screening. The ...

Dialog systems that realize dialog control with reinforcement learning have recently been proposed. However, reinforcement learning has an open problem that it requires a reward function that is difficult to set appropriately. To set the appropriate reward function automatically, we propose preference-learning based inverse reinforcement learning (PIRL) that estimates a reward function from dia...

In the standard reinforcement learning setting, the agent learns optimal policy solely from state transitions and rewards from the environment. We consider an extended setting where a trainer additionally provides feedback on the actions executed by the agent. This requires appropriately incorporating the feedback, even when the feedback is not necessarily accurate. In this paper, we present a ...

introduction: the n-methyl-d-aspartate (nmda) receptors, which have been implicated in memory formation, could be noncompetitively blocked by ketamine. the present study examines the short term effect of ketamine on induction of anterograde and retrograde amnesia in male rats using morris water maze (mwm). methods: male n-mri rats were randomly divided into nine experimental groups. mwm studies...

background: the cholinergic system plays an important role in learning and memory. administration of extracts of curcuma longa or its constituent, curcumin, have some roles in cognitive function in animals. the aim of the present study was to investigate the effects of curcumin in preventing spatial performance impairment induced by scopolamine, a cholinergic receptor antagonist, in rats using ...

background: acoustic noise is one of the universal pollutants of modern society. although the high level of noise adverse effects on human hearing has been known for many years, non-auditory effects of noise such as effects on cognition, learning, memory and reading, especially on children, have been less considered. factors which have negative impact on these features can also have a negative ...
