Measurement of indoor environment parameters in a classroom equipped with heat recovery unit

We demonstrate several ways to use morphological word analogies to examine the representation of complex words in semantic vector spaces. We present a set of morphological relations, each of which can be used to generate many word analogies. 1. We show that the difference-vectors&#...

Typové zařazení hradu Skála u Přeštic

Background: Protected health information burned in pixel data is not indicated for various reasons in DICOM. It complicates the secondary use of such data. In recent years, there have been several attempts to anonymize or de-identify DICOM files. Existing approaches have different const...

Identification and classification of DICOM files with burned-in text content

The ability to represent the meaning of words is one of the core parts of natural language understanding (NLU), with applications ranging across machine translation, summarization, question answering, information retrieval, etc. The need for reasoning in multilingual contexts and transferring kno...

Cross-lingual word analogies using linear transformations between semantic spaces

The connectivity of embedded systems is increasing accompanied with thriving technology such as Internet of Things/Everything (IoT/E), Connected Cars, Smart Cities, Industry 4.0, 5G or Software-Defined Everything. Apart from the benefits of these trends, the continuous networking offers hackers&#...

Training Strategies for OCR Systems for Historical Documents

Random Sample Consensus is a powerful paradigm that was successfully applied in various contexts, including Location Determination Problem, fundamental matrix estimation and global 3D surface registration, where many previously proposed algorithms can be interpreted as a particular implementation of t...

Vertex-transitive Haar graphs that are not Cayley graphs

The function of enzymatic proteins is given by their ability to bind specific small molecules into their active sites. These sites can often be found in pockets on a hypothetical boundary between the protein and its environment. Detection, analysis, and visualization of pockets fin...

Towards Translation of Semantics of Automotive Interface Description Models from Franca to AUTOSAR Frameworks : An Approach using Semantic Synergies

The automotive industry is eventually evolving into a complex network of services. The heterogeneous and distributed nature of automotive software systems demands flexible software components which can operate in different environments. Because of heterogeneous automotive development environments, the doma...

A Clustering Approach to Path Planning for Big Groups

The paper introduces a new method of planning paths for crowds in dynamic environment represented by a graph of vertices and edges, where the edge weight as well as the graph topology may change, but the method is also applicable to environment with a different representa...

Improving Word meaning representations using Wikipedia categories

In this paper we extend Skip-Gram and Continuous Bag-of-Words Distributional word representations models via global context information. We use a corpus extracted from Wikipedia, where articles are organized in a hierarchy of categories. These categories provide useful topical information about e...

Convexity in scientific collaboration networks

Convexity in a network (graph) has been recently defined as a property of each of its subgraphs to include all shortest paths between the nodes of that subgraph. It can be measured on the scale [0, 1] with 1 being assigned to fully convex networks. The largest c...

A genetic programming-based regression for extrapolating a blood glucose-dynamics model from interstitial glucose measurements and their derivatives

This paper illustrates the development and the applicability of an Evolutionary Computation approach to enhance the treatment of Type-1 diabetic patients that necessitate insulin injections. In fact, being such a disease associated to a malfunctioning pancreas that generates an insufficient amoun...

Automatic face recognition with well-calibrated confidence measures

Many Automatic face recognition (AFR) methods achieve a high recognition accuracy when the environment is well-controlled. In the case of moderately controlled or fully uncontrolled environments however, the performance of most techniques is dramatically reduced. As a result, the provision of...

Coherent subhologram-based computer generated display hologram

A modification of the subhologram-based approach to the calculation of a computer generated display hologram of a 3-D scene is presented. The hologram area is split into subholograms. For each of them, a perspective image with depth coordinate is rendered and converted to a po...

GMM classification of text-to-speech synthesis: identification of original speaker’s voice

This paper describes two experiments. The first one deals with evaluation of synthetic speech quality by reverse identification of original speakers whose voices had been used for several Czech text-to-speech (TTS) systems. The second experiment was aimed at evaluation of the influence ...

Collection and preprocessing of czech sign language corpus for sign language recognition

This paper discusses the design, recording and preprocessing of a Czech sign language corpus. The corpus is intended for training and testing of sign language recognition (SLR) systems. The UWB-07-SLR-P corpus contains video data of 4 signers recorded from 3 different perspective...

On the impact of labialization contexts on unit selection speech synthesis

This paper presents a study on coarticulatory labialization and the significance of its respecting/violation during selection and concatenation of speech units in the unit selection speech synthesis. The aim of this study is to improve the overall speech quality, especially to increase&...

Evaluation of various unit types in the unit selection approach for the Czech language using the Festival system

The present paper focuses on the utilization of concatenative speech synthesis, aiming to determine and compare the influence on the synthesized speech quality when various unit types are used in the unit selection approach. There are several unit types which can be used for t...
