ABSTRACT Marketing research consistently demonstrates that gender stereotypes influence the effectiveness of product recommendations. When artificial intelligence (AI) agents are designed with gendered features to enhance anthropomorphism, a follow‐up question is whether these agents' recommendations also shaped by stereotypes. To investigate this, current study employed shopping task featuring (utilitarian vs. hedonic), using both behavioral measures (purchase likelihood, personal interest,...

Abstract Spin‐casting or thermal evaporation in vacuum of a salt‐free, neutral, organic‐oxide ultra‐thin film as buffer layer with an aluminum (Al) cathode has become alternative approach for fabricating high‐performance organic and polymer light‐emitting diodes (O/PLEDs). [Guo et al., Appl. Phys. Lett . 2006 , 88 113501 89 053507] The electroluminescence efficiency phenyl‐substituted poly(para‐phenylene vinylene) copolymer‐based PLEDs is 0.16 cd A −1 when Al used the device cathode, but...

We address the problem of crafting visual routines for detection tasks. Emphasis is placed on both competition and learning to help with specific tasks involved in localization identification. Crafting presents difficult optimization problems leads evolutionary computation using a hybrid genetic architecture consisting natural selection, learning, their beneficial interactions. Base features representations represented as decision trees are evolved. The routine considered that eye detection....

Cognitive decline is one of the primary concerns in elderly population. Serious games have been used for different purposes related to care, such as physical therapy, cognitive training and mood management. There has scientific evidence regarding relationship between cognition autonomic nervous system (ANS) through heart rate variability (HRV). This paper explores changes ANS among people normal impaired measured HRV. Forty-eight subjects were classified into two groups: (NC) (n = 24) mild...

Classification of genetic sequence data available in public and private databases is an important problem using, understanding, retrieving, filtering correlating such large volumes information. Although a significant amount research effort being spent internationally on this problem, very few studies exist that compare different classification approaches terms objective quantitative performance criterion. In paper, we present experimental for sequences using both unsupervised supervised...

We describe a novel approach for fully automated face recognition and show its feasibility on large database of facial images (FERET). Our approach, based hybrid architecture consisting an ensemble radial basis function (RBF) neural networks inductive decision trees, combines the merits "abstractive" features with those "holistic" template matching. The benefits our include: 1) robust detection landmarks using 2) consensus methods over ensembles RBF networks. Experiments carried out k-fold...

As the proportion of elderly people continues to grow, so does concern about age-related cognitive decline. Serious games have been developed for training or treatment, but measuring activity autonomic nervous system (ANS) has not taken account. However, functioning known be heavily influenced by (ANS), and ANS can quantified using heart rate variability (HRV). This paper aims analyze physiological response in normal as they play two types serious HRV features from electrocardiography (ECG)....
