  2. Backdoor (computing) - Wikipedia

    en.wikipedia.org/wiki/Backdoor_(computing)

    A backdoor is a typically covert method of bypassing normal authentication or encryption in a computer, product, embedded device (e.g. a home router), or its embodiment (e.g. part of a cryptosystem, algorithm, chipset, or even a "homunculus computer"—a tiny computer-within-a-computer such as that found in Intel's AMT technology).

  3. Backpropagation - Wikipedia

    en.wikipedia.org/wiki/Backpropagation

    This is the reason why backpropagation requires that the activation function be differentiable. (Nevertheless, the ReLU activation function, which is non-differentiable at 0, has become quite popular, e.g. in AlexNet) The first factor is straightforward to evaluate if the neuron is in the output layer, because then = and

  4. Defensive programming - Wikipedia

    en.wikipedia.org/wiki/Defensive_programming

    Secure programming is the subset of defensive programming concerned with computer security. Security is the concern, not necessarily safety or availability (the software may be allowed to fail in certain ways). As with all kinds of defensive programming, avoiding bugs is a primary objective; however, the motivation is not as much to reduce the ...

    en.wikipedia.org/wiki/Computer_security_software

    Computer security software or cybersecurity software is any computer program designed to influence information security.This is often taken in the context of defending computer systems or data, yet can incorporate programs designed specifically for subverting computer systems due to their significant overlap, and the adage that the best defense is a good offense.

    en.wikipedia.org/wiki/Vanishing_gradient_problem

    Hardware advances have meant that from 1991 to 2015, computer power (especially as delivered by GPUs) has increased around a million-fold, making standard backpropagation feasible for networks several layers deeper than when the vanishing gradient problem was recognized.
