TL;DR: A deep architecture, AU-aware Deep Networks (AUDN), is proposed for facial expression recognition by elaborately utilizing the prior knowledge that the appearance variations caused by expression can be decomposed into a batch of local facial Action Units (AUs).
Abstract: In this paper, we propose to construct a deep architecture, AU-aware Deep Networks (AUDN), for facial expression recognition by elaborately utilizing the prior knowledge that the appearance variations caused by expression can be decomposed into a batch of local facial Action Units (AUs). The proposed AUDN is composed of three sequential modules: the first module consists of two layers, i.e., a convolution layer and a max-pooling layer, which aim to generate an over-complete representation encoding all expression-specific appearance variations over all possible locations; In the second module, an AU-aware receptive field layer is designed to search subsets of the over-complete representation, each of which aims at best simulating the combination of AUs; In the last module, multilayer Restricted Boltzmann Machines (RBM) are exploited to learn hierarchical features, which are then concatenated for final expression recognition. Experiments on three expression databases CK+, MMI and SFEW demonstrate the effectiveness of AUDN in both lab-controlled and wild environments. All our results are better than or at least competitive to the best known results.

TL;DR: The results show that TriLAR successfully recognized elementary activities using one or two sensors and significantly outperformed three standard, single-layer methods with all sensor placements.
Abstract: One of the essential tasks of healthcare and smart-living systems is to recognize the current activity of a particular user. Such activity recognition (AR) is demanding when only limited sensors are used, such as accelerometers. Given a small number of accelerometers, intelligent AR systems often use simple architectures, either general or specific for their AR. In this paper, a system for AR named TriLAR is presented. TriLAR has an AR-specific architecture consisting of three layers: (i) a bottom layer, where an arbitrary number of AR methods can be used to recognize the current activity; (ii) a middle layer, where the predictions from the bottom-layer methods are inputs for a hierarchical structure that combines domain knowledge and meta-classification; and (iii) a top layer, where a hidden Markov model is used to correct spurious transitions between the recognized activities from the middle layer. The middle layer has a hierarchical, three-level structure. First, a meta-classifier is used to make the initial separation between the most distinct activities. Second, domain knowledge in the form of rules is used to differentiate between the remaining activities, recognizing those of interest (i.e., static activities). Third, another meta-classifier deals with the remaining activities. In this way, each activity is recognized by the method best suited to it, leaving unrecognized activities to the next method. This architecture was tested on a dataset recorded using ten volunteers who acted out a complex, real-life scenario while wearing accelerometers placed on the chest, thigh, and ankle. The results show that TriLAR successfully recognized elementary activities using one or two sensors and significantly outperformed three standard, single-layer methods with all sensor placements.

TL;DR: This article presents a framework-based application, a simple action ad- venture game that is implemented using a conventional COP language, and shows how the JCop language supports the decla- ration of layer composition and expression of layer relationships.
Abstract: Program behavior that relies on contextual information, such as physical location or network accessibility, is common in today's appli- cations, yet its representation at the source code level is not suciently supported by programming languages. With context-oriented program- ming (COP), context-dependent behavior can be explicitly modularized and dynamically activated. The available COP implementations oer lan- guage constructs that allow to describe context-dependent functionality and to specify for which control flows this functionality should be exe- cuted. Since these language constructs require modifications to the source code, the contemporary approaches limit the use of COP to program parts whose source code is accessible to the developer (the user code). The dy- namic control over context-dependent behavior in frameworks cannot be directly addressed by COP as this would imply changes to the source code. Instead, context-dependent behavior is addressed whenever a control flow from the framework code enters the user code. Context composition must be addressed at any of these control flow entry points, which may lead to a redundant specification of this functionality. As a result, dynamic control over layers emerges as a crosscutting concern that obstructs the separation of concerns. In this article, we discuss crosscutting layer composition in framework- based applications in detail. Moreover, we discuss limitations for the ex- pression of semantic relationships of layers that might lead to code du- plication. We present a framework-based application, a simple action ad- venture game that we implemented using a conventional COP language. Along this example, we show how our JCop language supports the decla- ration of layer composition and expression of layer relationships.

Abstract: Scalability and fault tolerance are important features of modern applications designed for the distributed, loosely-coupled computer systems. In the paper, two-layer scalable structures for storing data in a distributed RAM of a multicomputer SD2DS are introduced. A data unit of SD2DS a component is split into a header and a body. The header identifies the body and contains its address in a network. The headers are stored in the first layer of SD2DS, called the component file, while the bodies are stored in the second layer, called the component storage. Both layers are managed independently. Details of the management algorithms are given, along with SD2DS variant suitable for storing plain records of data. The SD2DS is compared to similar distributed structures and frameworks. Comparison considerations together with test results are also given. The results proved superiority of SD2DS over similar structures.

TL;DR: In this paper, a layer stack may be associated with a first logical display having a first resolution, and a region containing parts of one or more surfaces, at the first position of the layer stack and corresponding to the first resolution of the first logical displays, may be rendered and output, based on a display projection, to a first physical display.
Abstract: Systems and methods include utilizing a layer stack to indirectly associate logical and physical display content. A layer stack may decouple content from content presentation details at a physical display, facilitating the implementation of mirroring, spanning, and other multiple-display modes across non-contiguous display devices with disparate resolutions, densities, and other characteristics, while maintaining native device configuration settings. In one implementation, a layer stack may be a collection of surfaces. The layer stack may be associated with a first logical display having a first resolution. A region containing parts of one or more surfaces, at a first position of the layer stack and corresponding to the first resolution of the first logical display, may be rendered and output, based on a display projection, to a first physical display. Further implementations may use combinations of additional logical displays, physical displays, or layer stacks to implement various multiple-display modes.
