  2. Elements of AI - Wikipedia

    en.wikipedia.org/wiki/Elements_of_AI

    The course, originally launched in 2018, is designed and organized by the University of Helsinki and learning technology company MinnaLearn. [2] The course includes modules on machine learning , neural networks , the philosophy of artificial intelligence, and using artificial intelligence to solve problems.

  3. Neural network - Wikipedia

    en.wikipedia.org/wiki/Neural_network

    While early artificial neural networks were physical machines, [3] today they are almost always implemented in software. Neurons in an artificial neural network are usually arranged into layers, with information passing from the first layer (the input layer) through one or more intermediate layers ( the hidden layers ) to the final layer (the ...

  4. Neural network (machine learning) - Wikipedia

    en.wikipedia.org/wiki/Neural_network_(machine...

    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.

  5. Types of artificial neural networks - Wikipedia

    en.wikipedia.org/wiki/Types_of_artificial_neural...

    Artificial neural networks are computational models inspired by biological neural networks, and are used to approximate functions that are generally unknown. Particularly, they are inspired by the behaviour of neurons and the electrical signals they convey between input (such as from the eyes or nerve endings in the hand), processing, and ...

  6. Activation function - Wikipedia

    en.wikipedia.org/wiki/Activation_function

    The activation function of a node in an artificial neural network is a function that calculates the output of the node based on its individual inputs and their weights. Nontrivial problems can be solved using only a few nodes if the activation function is nonlinear . [ 1 ]

  7. Geoffrey Hinton - Wikipedia

    en.wikipedia.org/wiki/Geoffrey_Hinton

    Hinton taught a free online course on Neural Networks on the education platform Coursera in 2012. [47] He joined Google in March 2013 when his company, DNNresearch Inc., was acquired, and was at that time planning to "divide his time between his university research and his work at Google".

  8. Andrej Karpathy - Wikipedia

    en.wikipedia.org/wiki/Andrej_Karpathy

    Karpathy is a founding member of the artificial intelligence research group OpenAI, [19] [20] where he was a research scientist from 2015 to 2017. [18] In June 2017 he became Tesla's director of artificial intelligence and reported to Elon Musk. [21] [7] [22] He was named one of MIT Technology Review's Innovators Under 35 for 2020. [23]

  9. Computational neurogenetic modeling - Wikipedia

    en.wikipedia.org/wiki/Computational_neurogenetic...

    An example of an artificial neural network that uses supervised learning is a multilayer perceptron (MLP). In unsupervised learning, an artificial neural network is trained using only inputs. Unsupervised learning is the learning mechanism by which a type of artificial neural network known as a self-organizing map (SOM) learns. Some types of ...
