  2. Stochastic gradient descent - Wikipedia

    en.wikipedia.org/wiki/Stochastic_gradient_descent

    Adam [41] (short for Adaptive Moment Estimation) is a 2014 update to the RMSProp optimizer combining it with the main feature of the Momentum method. [42] In this optimization algorithm, running averages with exponential forgetting of both the gradients and the second moments of the gradients are used.

  3. Rprop - Wikipedia

    en.wikipedia.org/wiki/Rprop

    RMSprop addresses this problem by keeping the moving average of the squared gradients for each weight and dividing the gradient by the square root of the mean square. [ citation needed ] RPROP is a batch update algorithm .

  4. IEC 60269 - Wikipedia

    en.wikipedia.org/wiki/IEC_60269

    In electrical engineering, IEC 60269 is a set of technical standards for low-voltage power fuses. [1] The standard is in four volumes, which describe general requirements, fuses for industrial and commercial applications, fuses for residential applications, and fuses to protect semiconductor devices.

  5. Fuse cutout - Wikipedia

    en.wikipedia.org/wiki/Fuse_cutout

    In electrical distribution, a fuse cutout or cut-out fuse (often referred to as a cutout) is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to ...

  6. Stochastic gradient Langevin dynamics - Wikipedia

    en.wikipedia.org/wiki/Stochastic_Gradient_Langev...

    SGLD can be applied to the optimization of non-convex objective functions, shown here to be a sum of Gaussians. Stochastic gradient Langevin dynamics (SGLD) is an optimization and sampling technique composed of characteristics from Stochastic gradient descent, a Robbins–Monro optimization algorithm, and Langevin dynamics, a mathematical extension of molecular dynamics models.

  7. Fuse (electrical) - Wikipedia

    en.wikipedia.org/wiki/Fuse_(electrical)

    A time-delay fuse (also known as an anti-surge or slow-blow fuse) is designed to allow a current which is above the rated value of the fuse to flow for a short period of time without the fuse blowing. These types of fuse are used on equipment such as motors, which can draw larger than normal currents for up to several seconds while coming up to ...

  8. Resettable fuse - Wikipedia

    en.wikipedia.org/wiki/Resettable_fuse

    A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits. The device is also known as a multifuse or polyfuse or polyswitch .

  9. 807 (vacuum tube) - Wikipedia

    en.wikipedia.org/wiki/807_(vacuum_tube)

    The screen voltage is the same, at 300, but its dissipation rises to 3.5 watts. 37 watts of R.F. power is produced from 220 mW of drive but only a 50% duty cycle is allowed. The maximum allowable negative control grid, g1 excursion allowable is -200 volts and average control grid current is 5mA in both A.M. and CW modes. [ 1 ]
