Layer-Wise Relevance Propagation for Neural Networks with Local Renormalization Layers

Abstract: Layer-wise relevance propagation is a framework which allows to decompose the prediction of a deep neural network computed over a sample, e.g. an image, down to relevance scores for the single input dimensions of the sample such as subpixels of an image. While this approach can be applied directly to generalized linear mappings, product type non-linearities are not covered. This paper proposes an approach to extend layer-wise relevance propagation to neural networks with local renormalization layers, which is a very common product-type non-linearity in convolutional neural networks. We evaluate the proposed method for local renormalization layers on the CIFAR-10, Imagenet and MIT Places datasets.

When and How Does Business Group Affiliation Promote Firm Innovation? A Tale of Two Emerging Economies

Abstract: Using a comparative institutional perspective, we explore whether business groups' roles in facilitating affiliate firms' innovation varies by country and time period. We compare the innovativeness of firms affiliated with business groups to that of independent firms in two emerging economies: South Korea and Taiwan. On average, business group affiliates outperform independent firms in South Korea, but not in Taiwan, and in the early 1990s, but not in the late 1990s. The existence of alternative institutional infrastructures for innovation might explain these differences. Groups' abilities to share technological knowledge and financial resources among affiliates enables them to create value by promoting innovation in emerging economies, but groups' diversification might inhibit individual affiliates' innovativeness.

Investigating factors that influence social presence and learning outcomes in distance higher education

Abstract: There are many factors that influence distance learning especially in higher education where collaborative and communicative discourse is necessary for pursuing knowledge Social presence, among other factors, is an important concept to be facilitated, developed and sustained in distance higher education as it promotes and supports discourse based learning This study examines the relationship among demographic and other variables, social presence and learning satisfaction Results showed demographic variables, such as gender, online learning experience and work status were not significant factors in terms of influencing on either social presence or learning satisfaction While media integration and instructor's quality teaching were significant predictors of both social presence and learning satisfaction, interactivity among participants was a predictor of social presence but not of learning satisfaction Along with the study findings, some implications were discussed for online learning practitioners in higher education setting
