Recent advances in sensor based human activity recognition (HAR) have exploited deep hybrid networks to improve the performance. These models combine Convolutional Neural Networks (CNNs) and Recurrent (RNNs) leverage their complementary advantages, achieve impressive results. However, roles associations of different sensors HAR are not fully considered by these models, leading insufficient mult...

Story segmentation of news broadcasts has been shown to improve the accuracy of the subsequent processes such as question answering and information retrieval. In previous work, a decision tree trained on automatically extracted lexical and acoustic features was trained to predict story boundaries, using hypothesized sentence boundaries to define potential story boundaries. In this paper, we emp...

In this paper we present an O(n(m + logn))-time algorithm for computing a minimum-weight tree support (if one exists) of a hypergraph H = (V, S) with n vertices and m hyperedges. This improves the previously best known algorithm with running time O(nm). A support of H is a graph G on V such that each hyperedge in S induces a connected subgraph in G. If G is a tree, it is called a tree support a...

Several techniques for the computation of gamut boundaries have been presented in the past. In this paper we take an in-depth look at some of the gamut boundary descriptors used when performing today’s gamut mapping algorithms. We present a method for evaluating the mismatch introduced when using a descriptor to approximate the boundary of a device gamut. First, a visually verified reference ga...

The Kohonen self-organizing feature map (SOM) has several important properties that can be used within the data mining/knowledge discovery and exploratory data analysis process. A key characteristic of the SOM is its topology preserving ability to map a multi-dimensional input into a two dimensional form. This feature is used for classification and clustering of data. However, a great deal of e...

Abstract Great importance is attributed to a transition towards bioeconomy regime. The can foster more sustainable production and consumption systems therefore contribute the achievement of United Nations Sustainable Development Goals. This facing several inhibitors, such as dysfunctional communication between different actors insufficient innovative activity. Scholars practitioners consider co...
