  2. NACK-Oriented Reliable Multicast - Wikipedia

    en.wikipedia.org/wiki/NACK-Oriented_Reliable...

    A NORM node refers to an individual node taking part in a NORM session. Each node has a unique identifier. When a node transmits a NORM message, this identifier is noted as the source_id. A NORM instance refers to an individual node in the context of a continuous segment of a NORM session. When a node joins a NORM session, it has a unique node ...

  3. Normalization (machine learning) - Wikipedia

    en.wikipedia.org/wiki/Normalization_(machine...

    Layer normalization (LayerNorm) [13] is a popular alternative to BatchNorm. Unlike BatchNorm, which normalizes activations across the batch dimension for a given feature, LayerNorm normalizes across all the features within a single data sample. Compared to BatchNorm, LayerNorm's performance is not affected by batch size.

  4. Multitier architecture - Wikipedia

    en.wikipedia.org/wiki/Multitier_architecture

    Overview of a three-tier application. Three-tier architecture is a client-server software architecture pattern in which the user interface (presentation), functional process logic ("business rules"), computer data storage and data access are developed and maintained as independent modules, most often on separate platforms. [14]

  5. Batch normalization - Wikipedia

    en.wikipedia.org/wiki/Batch_normalization

    The explanation made in the original paper [1] was that batch norm works by reducing internal covariate shift, but this has been challenged by more recent work. One experiment [2] trained a VGG-16 network [5] under 3 different training regimes: standard (no batch norm), batch norm, and batch norm with noise added to each layer during training ...

  6. Separation of concerns - Wikipedia

    en.wikipedia.org/wiki/Separation_of_concerns

    The mechanisms for modular or object-oriented programming that are provided by a programming language are mechanisms that allow developers to provide SoC. [4] For example, object-oriented programming languages such as C#, C++, Delphi, and Java can separate concerns into objects, and architectural design patterns like MVC or MVP can separate presentation and the data-processing (model) from ...

  7. Software architecture - Wikipedia

    en.wikipedia.org/wiki/Software_architecture

    Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations.

  8. Layer (object-oriented design) - Wikipedia

    en.wikipedia.org/wiki/Layer_(object-oriented_design)

    In software object-oriented design, a layer is a group of classes that have the same set of link-time module dependencies to other modules. [1] In other words, a layer is a group of reusable components that are reusable in similar circumstances. In programming languages, the layer distinction is often expressed as "import" dependencies between ...

  9. C4 model - Wikipedia

    en.wikipedia.org/wiki/C4_model

    The C4 model was created by the software architect Simon Brown between 2006 and 2011 on the roots of Unified Modelling Language (UML) and the 4+1 architectural view model. The launch of an official website under a Creative Commons license [ 3 ] and an article [ 4 ] published in 2018 popularised the emerging technique.
