We present SIMDEX, a new technique for serving exact top-K recommendations on matrix factorization models that measures and optimizes for the similarity between users in the model. Previous serving techniques presume a high degree of similarity (e.g., L2 or cosine distance) among users and/or items in MF models; however, as we demonstrate, the most accurate models are not guaranteed to exhibit ...

One of the success factors of Work Integrated Learning (WIL) is to provide the appropriate content to the users, both suitable for the topics they are currently working on, and their experience level in these topics. Our main contributions in this paper are (i) overcoming the problem of sparse content annotation by using a network based recommendation approach called Associative Network, which ...

This paper proposes a novel regularization approach for Extreme Learning Machines. Regularization is performed using a priori spacial information expressed by an affinity matrix. We show that the use of this type of a priori information is similar to perform Tikhonov regularization. Furthermore, if a parameter free affinity matrix is used, like the cosine similarity matrix, regularization is pe...

In this paper, we propose spatial propagation networks for learning the affinity matrix for vision tasks. We show that by constructing a row/column linear propagation model, the spatially varying transformation matrix exactly constitutes an affinity matrix that models dense, global pairwise relationships of an image. Specifically, we develop a three-way connection for the linear propagation mod...

in this research, issr technique was applied to assess genetic diversity among 56 chickpea lines. out of 34 primers, nine primers produced appropriate banding patterns and produced 35 polymorphic bands in chickpea lines. mean percentage of polymorphism of the primers was 66.01 with range of 25 to 100 percent. mean of nei's genetic diversity and shannon information index over all primers we...

in order to study the genetic diversity of the causal agent of fusarium wilting in chickpea, two techniques including rapd and pcr-rflp were used. in rapd-pcr technique, all 14 primers could show the diversity among the isolates. after studding the banding patterns of 14 primers, a dendrogram based on similarity matrix was constructed. the rapd dendrogram analysis could not separate isolates ba...
