    In particular, three data sets are commonly used in different stages of the creation of the model: training, validation, and test sets. The model is initially fit on a training data set, [3] which is a set of examples used to fit the parameters (e.g. weights of connections between neurons in artificial neural networks) of the model. [4]

    In machine learning, a neural network (also artificial neural network or neural net, abbreviated ANN or NN) is a model inspired by the structure and function of biological neural networks in animal brains. [1] [2] An ANN consists of connected units or nodes called artificial neurons, which loosely model the neurons in the brain. Artificial ...

    en.wikipedia.org/wiki/Winograd_schema_challenge

    The Winograd schema challenge (WSC) is a test of machine intelligence proposed in 2012 by Hector Levesque, a computer scientist at the University of Toronto.Designed to be an improvement on the Turing test, it is a multiple-choice test that employs questions of a very specific structure: they are instances of what are called Winograd schemas, named after Terry Winograd, professor of computer ...

  7. Learning rule - Wikipedia

    en.wikipedia.org/wiki/Learning_rule

    Depending on the complexity of the model being simulated, the learning rule of the network can be as simple as an XOR gate or mean squared error, or as complex as the result of a system of differential equations. The learning rule is one of the factors which decides how fast or how accurately the neural network can be developed.

    Sample images from MNIST test dataset The MNIST database ( Modified National Institute of Standards and Technology database [ 1 ] ) is a large database of handwritten digits that is commonly used for training various image processing systems.

  9. Bootstrap aggregating - Wikipedia

    Bagging leads to "improvements for unstable procedures", [2] which include, for example, artificial neural networks, classification and regression trees, and subset selection in linear regression. [3] Bagging was shown to improve preimage learning.
