  2. Convolutional neural network - Wikipedia

    en.wikipedia.org/wiki/Convolutional_neural_network

    A convolutional neural network (CNN) is a regularized type of feed-forward neural network that learns features by itself via filter (or kernel) optimization. This type of deep learning network has been applied to process and make predictions from many different types of data including text, images and audio. [1]

  3. Converse (logic) - Wikipedia

    en.wikipedia.org/wiki/Converse_(logic)

    Let S be a statement of the form P implies Q (P → Q). Then the converse of S is the statement Q implies P (Q → P). In general, the truth of S says nothing about the truth of its converse, [2] unless the antecedent P and the consequent Q are logically equivalent. For example, consider the true statement "If I am a human, then I am mortal."

  4. Elementary cellular automaton - Wikipedia

    en.wikipedia.org/wiki/Elementary_cellular_automaton

    Class 4: Cellular automata which form areas of repetitive or stable states, but also form structures that interact with each other in complicated ways. An example is rule 110. Rule 110 has been shown to be capable of universal computation. [5]

    The normal equations can be derived directly from a matrix representation of the problem as follows. The objective is to minimize = ‖ ‖ = () = +.Here () = has the dimension 1x1 (the number of columns of ), so it is a scalar and equal to its own transpose, hence = and the quantity to minimize becomes

  6. Polyhedral combinatorics - Wikipedia

    en.wikipedia.org/wiki/Polyhedral_combinatorics

    This is in sharp contrast with (non-simple) neighborly polytopes whose graph is a complete graph; there can be many different neighborly polytopes for the same graph. Another proof of this theorem based on unique sink orientations was given by Kalai (1988) , and Friedman (2009) showed how to use this theorem to derive a polynomial time ...

    Related titles should be described in Simple linear regression, while unrelated titles should be moved to Simple linear regression (disambiguation). ( May 2019 ) Line fitting is the process of constructing a straight line that has the best fit to a series of data points.

  8. Complex random variable - Wikipedia

    en.wikipedia.org/wiki/Complex_random_variable

    Another example of a complex random variable is the uniform distribution over the filled unit circle, i.e. the set {| |}.This random variable is an example of a complex random variable for which the probability density function is defined.

  9. Reservoir computing - Wikipedia

    en.wikipedia.org/wiki/Reservoir_computing

    The first examples of reservoir neural networks demonstrated that randomly connected recurrent neural networks could be used for simple forms of interval and speech discrimination [3] [4]. In these early models the memory in the network took the form of both short-term synaptic plasticity and activity mediated by recurrent connections.
