  2. Quantum efficiency - Wikipedia

    en.wikipedia.org/wiki/Quantum_efficiency

    A graph showing variation of quantum efficiency with wavelength of a CCD chip from Wide Field and Planetary Camera 2, formerly installed on the Hubble Space Telescope.. The term quantum efficiency (QE) may apply to incident photon to converted electron (IPCE) ratio [1] of a photosensitive device, or it may refer to the TMR effect of a magnetic tunnel junction.

  3. Dixon's Q test - Wikipedia

    en.wikipedia.org/wiki/Dixon's_Q_test

    To apply a Q test for bad data, arrange the data in order of increasing values and calculate Q as defined: Q = gap range {\displaystyle Q={\frac {\text{gap}}{\text{range}}}} Where gap is the absolute difference between the outlier in question and the closest number to it.

  4. Rayleigh–Ritz method - Wikipedia

    en.wikipedia.org/wiki/Rayleigh–Ritz_method

    For example, in the case of beam deflection problems it is wise to use a deformed shape that is analytically similar to the expected solution. A quartic may fit most of the easy problems of simply linked beams even if the order of the deformed solution may be lower.

  5. Knapsack problem - Wikipedia

    en.wikipedia.org/wiki/Knapsack_problem

    The most common problem being solved is the 0-1 knapsack problem, which restricts the number of copies of each kind of item to zero or one. Given a set of items numbered from 1 up to , each with a weight and a value , along with a maximum weight capacity ,

  6. Quantum machine learning - Wikipedia

    en.wikipedia.org/wiki/Quantum_machine_learning

    For example, some mathematical and numerical techniques from quantum physics are applicable to classical deep learning and vice versa. [ 23 ] [ 24 ] [ 25 ] Furthermore, researchers investigate more abstract notions of learning theory with respect to quantum information, sometimes referred to as "quantum learning theory".

  7. Signal-to-quantization-noise ratio - Wikipedia

    en.wikipedia.org/wiki/Signal-to-quantization...

    Signal-to-quantization-noise ratio (SQNR or SN q R) is widely used quality measure in analysing digitizing schemes such as pulse-code modulation (PCM).

  8. Sequential probability ratio test - Wikipedia

    en.wikipedia.org/wiki/Sequential_probability...

    The SPRT is currently the predominant method of classifying examinees in a variable-length computerized classification test (CCT) [citation needed].The two parameters are p 1 and p 2 are specified by determining a cutscore (threshold) for examinees on the proportion correct metric, and selecting a point above and below that cutscore.

  9. Mills ratio - Wikipedia

    en.wikipedia.org/wiki/Mills_ratio

    The inverse Mills ratio is the ratio of the probability density function to the complementary cumulative distribution function of a distribution. Its use is often motivated by the following property of the truncated normal distribution. If X is a random variable having a normal distribution with mean μ and variance σ 2, then
