  2. Hidden Field Equations - Wikipedia

    en.wikipedia.org/wiki/Hidden_Field_Equations

    The HFE family of cryptosystems is based on the hardness of the problem of finding solutions to a system of multivariate quadratic equations (the so-called MQ problem) since it uses private affine transformations to hide the extension field and the private polynomials. Hidden Field Equations also have been used to construct digital signature ...

  3. Hidden layer - Wikipedia

    en.wikipedia.org/wiki/Hidden_layer

    Example of hidden layers in a MLP. In artificial neural networks, a hidden layer is a layer of artificial neurons that is neither an input layer nor an output layer. The simplest examples appear in multilayer perceptrons (MLP), as illustrated in the diagram. [1] An MLP without any hidden layer is essentially just a linear model.

  4. FIR transfer function - Wikipedia

    en.wikipedia.org/wiki/FIR_Transfer_function

    h() is a transfer function of an impulse response to the input. The convolution allows the filter to only be activated when the input recorded a signal at the same time value. This filter returns the input values (x(t)) if k falls into the support region of function h. This is the reason why this filter is called finite response.

  5. Hidden Markov model - Wikipedia

    en.wikipedia.org/wiki/Hidden_Markov_model

    Figure 1. Probabilistic parameters of a hidden Markov model (example) X — states y — possible observations a — state transition probabilities b — output probabilities. In its discrete form, a hidden Markov process can be visualized as a generalization of the urn problem with replacement (where each item from the urn is returned to the original urn before the next step). [7]

  6. Deep learning - Wikipedia

    en.wikipedia.org/wiki/Deep_learning

    Deep learning is a subset of machine learning that focuses on utilizing neural networks to perform tasks such as classification, regression, and representation learning.The field takes inspiration from biological neuroscience and is centered around stacking artificial neurons into layers and "training" them to process data.

  7. Wireless power transfer - Wikipedia

    en.wikipedia.org/wiki/Wireless_power_transfer

    In inductive coupling (electromagnetic induction [57] [77] or inductive power transfer, IPT), power is transferred between coils of wire by a magnetic field. [16] The transmitter and receiver coils together form a transformer. [16] [57] An alternating current (AC) through the transmitter coil (L1) creates an oscillating magnetic field (B) by ...

  8. Death - Wikipedia

    en.wikipedia.org/wiki/Death

    The human skull is used universally as a symbol of death. Death is the end of life ; the irreversible cessation of all biological functions that sustain a living organism.

  9. TikTok - Wikipedia

    en.wikipedia.org/wiki/TikTok

    TikTok, known in mainland China and Hong Kong [3] as Douyin (Chinese: 抖音; pinyin: Dǒuyīn; lit. 'Shaking Sound'), [4] is a short-form video-hosting service owned by Chinese internet company ByteDance.
