  2. Convolution power - Wikipedia

    en.wikipedia.org/wiki/Convolution_power

    If x is itself suitably differentiable, then from the properties of convolution, one has {} = () = {()}where denotes the derivative operator. Specifically, this holds if x is a compactly supported distribution or lies in the Sobolev space W 1,1 to ensure that the derivative is sufficiently regular for the convolution to be well-defined.

  6. Online shopping - Wikipedia

    en.wikipedia.org/wiki/Online_shopping

    In a conventional retail store, clerks are generally available to answer questions. Some online stores have real-time chat features, but most rely on e-mails or phone calls to handle customer questions. Even if an online store is open 24 hours a day, seven days a week, the customer service team may only be available during regular business hours.

  7. Convolutional layer - Wikipedia

    en.wikipedia.org/wiki/Convolutional_layer

    In artificial neural networks, a convolutional layer is a type of network layer that applies a convolution operation to the input. Convolutional layers are some of the primary building blocks of convolutional neural networks (CNNs), a class of neural network most commonly applied to images, video, audio, and other data that have the property of uniform translational symmetry.

  8. Graphical user interface - Wikipedia

    en.wikipedia.org/wiki/Graphical_user_interface

    A graphical user interface (GUI) showing various elements: radio buttons, checkboxes, and other elements. A graphical user interface, or GUI [a], is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation.
