    en.wikipedia.org/wiki/Conditional_probability_table

    In statistics, the conditional probability table (CPT) is defined for a set of discrete and mutually dependent random variables to display conditional probabilities of a single variable with respect to the others (i.e., the probability of each possible value of one variable if we know the values taken on by the other variables).

    To briefly interrupt your fighting: Murphy (Machine Learning: A Probabilistic Perspective, 2012) does not require variance -> 0. He shows an equivalence of k-means to "hard EM" with arbitrary but fixed variance. See 11.4.2.5. --Chire 12:00, 3 December 2019 (UTC) @Chire: True, and thanks for the constructive contribution.

  6. Categorical distribution - Wikipedia

    en.wikipedia.org/wiki/Categorical_distribution

    The K-dimensional categorical distribution is the most general distribution over a K-way event; any other discrete distribution over a size-K sample space is a special case. The parameters specifying the probabilities of each possible outcome are constrained only by the fact that each must be in the range 0 to 1, and all must sum to 1.

    The theory makes it clear that when a learning rate of is used, the correct formula for retrieving the posterior probability is now = (()). In conclusion, by choosing a loss function with larger margin (smaller γ {\displaystyle \gamma } ) we increase regularization and improve our estimates of the posterior probability which in turn improves ...

  8. Learning rate - Wikipedia

    en.wikipedia.org/wiki/Learning_rate

    In the adaptive control literature, the learning rate is commonly referred to as gain. [2] In setting a learning rate, there is a trade-off between the rate of convergence and overshooting. While the descent direction is usually determined from the gradient of the loss function, the learning rate determines how big a step is taken in that ...

  9. Stochastic gradient descent - Wikipedia

    The step size is denoted by (sometimes called the learning rate in machine learning) and here ":=" denotes the update of a variable in the algorithm. In many cases, the summand functions have a simple form that enables inexpensive evaluations of the sum-function and the sum gradient.
