Commutation Theorem
In mathematics, a commutation theorem explicitly identifies the commutant of a specific von Neumann algebra acting on a Hilbert space in the presence of a trace. The first such result was proved by Francis Joseph Murray and John von Neumann in the 1930s and applies to the von Neumann algebra generated by a discrete group or by the dynamical system associated with a measurable transformation preserving a probability measure. Another important application is in the theory of unitary representations of unimodular locally compact groups, where the theory has been applied to the regular representation and other closely related representations. In particular this framework led to an abstract version of the Plancherel theorem for unimodular locally compact groups due to Irving Segal and Forrest Stinespring and an abstract Plancherel theorem for spherical functions associated with a Gelfand pair due to Roger Godement. Their work was put in final form in the 1950s by Jacques Dixmier as part of the theory of Hilbert algebras. It was not until the late 1960s, prompted partly by results in algebraic quantum field theory and quantum statistical mechanics due to the school of Rudolf Haag, that the more general non-tracial Tomita–Takesaki theory was developed, heralding a new era in the theory of von Neumann algebras.

Convolutional Neural Networks for Image Classification
Convolutional neural networks learn directly from data and are widely used for image recognition and classification. Convolutional Neural Networks (CNNs) have been considered one of the best machine learning algorithms to analyze grid-like structured data, such as images.

An Optimal House Price Prediction Algorithm: XGBoost
An accurate prediction of house prices is a fundamental requirement for various sectors, including real estate and mortgage lending. It is widely recognized that a property’s value is not solely determined by its physical attributes but is significantly influenced by its surrounding neighborhood. Meeting the diverse housing needs of individuals while balancing budget constraints is a primary concern for real estate developers.

Challenges in Agricultural Image Datasets and Filter Algorithms
Smart farming is facilitated by remote sensing because it allows for the inexpensive monitoring of crops, crop classification, stress detection yield forecasting using lightweight sensors over a wide area in a relatively short amount of time. Deep learning (DL)-based computer vision is one of the important aspects of the automatic detection and monitoring of plant stress. Challenges for DL algorithms in the agricultural dataset include size variation in objects, image resolution, background clutter, precise annotation with the expert, high object density or the demand for different spectral images.

Software Vulnerability Lifecycle and Vulnerability Markets
Vulnerability lifecycles and the vulnerability markets are related in a manner that can lead to serious security and economic risks, especially regarding black markets. The subject of software security has emerged as a primary concern and has once again been raised by individuals and government agencies in terms of risks of violations regarding information security, cybersecurity, and the consequences for the economy, especially in relation to attacks from actors with special agendas. Therefore, software vulnerabilities have major effects on the developmental paths of technology, development, and investment.

CLARIN
CLARIN is a European research network working in the field of archiving and processing of language-related resources in the humanities and social sciences. CLARIN is an acronym for Common Language Resources and Technology Infrastructure. CLARIN is a community of scholars of various disciplines and a network of institutions. The scholars use CLARIN as a forum for joined developments and exchange of resources. They also exchange information on standards and procedures for long time archiving of research data. The institutions of CLARIN offer services in the same field. On the European level, CLARIN is an independent body operating under European law as a European Research Infrastructure Community (ERIC). CLARIN ERIC represents the CLARIN community in the public and coordinates individual efforts in the field. CLARIN is listed in the Registry of Research Data Repositories re3data.org. For published literature on CLARIN, see (and please cite!) the following publications:

Consumerization
Consumerization is the reorientation of product and service designs to focus on (and market to) the end user as an individual consumer, in contrast with an earlier era of only organization-oriented offerings (designed solely for business-to-business or business-to-government sales). Technologies whose first commercialization was at the inter-organization level thus have potential for later consumerization. The emergence of the individual consumer as the primary driver of product and service design is most commonly associated with the IT industry, as large business and government organizations dominated the early decades of computer usage and development. Thus the microcomputer revolution, in which electronic computing moved from exclusively enterprise and government use to include personal computing, is a cardinal example of consumerization. But many technology-based products, such as calculators and mobile phones, have also had their origins in business markets, and only over time did they become dominated by high-volume consumer usage, as these products commoditized and prices fell. An example of enterprise software that became consumer software is optical character recognition software, which originated with banks and postal systems (to automate cheque clearing and mail sorting) but eventually became personal productivity software. In a different sense, consumerization of IT is the proliferation of personally owned IT at the workplace (in addition to, or even instead of, company-owned IT), which originates in the consumer market, to be used for professional purposes. This bring your own device trend has significantly changed corporate IT policies, as employees now often use their own laptops, netbooks, tablets, and smartphones on the hardware side, and social media, web conferencing, cloud storage, and software as a service on the software side.

Ket
Ket is an open source algebra editor. It is distinct from other editors which focus on automated computation such as integration or equation solving (Mathematica, Maple etc.) or on the presentation quality of the resulting document (e.g. LaTeX). The focus of Ket is to enable the user to perform algebra quickly and efficiently. It is therefore closer to a text editor, whiteboard or to the back of an envelope. However, it does provide a range of tools to automate the individual steps of algebra.

FamilyGuard
The residential environment is constantly evolving technologically. With this evolution, sensors have become intelligent interconnecting home appliances, personal computers, and mobile devices. Despite the benefits of this interaction, these devices are also prone to security threats and vulnerabilities. Ensuring the security of smart homes is challenging due to the heterogeneity of applications and protocols involved in this environment. This entry proposes the FamilyGuard architecture to add a new layer of security and simplify management of the home environment by detecting network traffic anomalies.
