  2. Contrastive Language-Image Pre-training - Wikipedia

    en.wikipedia.org/wiki/Contrastive_Language-Image...

    CLIP has been used as a component in multimodal learning. For example, during the training of Google DeepMind's Flamingo (2022), [33] the authors trained a CLIP pair, with BERT as the text encoder and NormalizerFree ResNet F6 [34] as the image encoder. The image encoder of the CLIP pair was taken with parameters frozen and the text encoder was ...

  3. Self-supervised learning - Wikipedia

    en.wikipedia.org/wiki/Self-supervised_learning

    Contrastive self-supervised learning uses both positive and negative examples. The loss function in contrastive learning is used to minimize the distance between positive sample pairs, while maximizing the distance between negative sample pairs. [9] An early example uses a pair of 1-dimensional convolutional neural networks to process a pair of ...

  4. Contrastive Hebbian learning - Wikipedia

    en.wikipedia.org/wiki/Contrastive_Hebbian_learning

    Contrastive Hebbian learning is a biologically plausible form of Hebbian learning. It is based on the contrastive divergence algorithm, which has been used to train a variety of energy-based latent variable models. [1] In 2003, contrastive Hebbian learning was shown to be equivalent in power to the backpropagation algorithms commonly used in ...

    Hence, more tailor-made language design can be adopted; examples include awareness raising teaching method and hierarchical learning teaching curriculum. Second language learning: Awareness raising is the major contribution of CA in second language learning. This includes CA's abilities to explain observed errors and to outline the differences ...

  6. Large language model - Wikipedia

    en.wikipedia.org/wiki/Large_language_model

    A large language model (LLM) is a type of machine learning model designed for natural language processing tasks such as language generation.LLMs are language models with many parameters, and are trained with self-supervised learning on a vast amount of text.

  7. Restricted Boltzmann machine - Wikipedia

    en.wikipedia.org/wiki/Restricted_Boltzmann_machine

    Diagram of a restricted Boltzmann machine with three visible units and four hidden units (no bias units) A restricted Boltzmann machine (RBM) (also called a restricted Sherrington–Kirkpatrick model with external field or restricted stochastic Ising–Lenz–Little model) is a generative stochastic artificial neural network that can learn a probability distribution over its set of inputs.

  8. Unsupervised learning - Wikipedia

    en.wikipedia.org/wiki/Unsupervised_learning

    Unsupervised learning is a framework in machine learning where, in contrast to supervised learning, algorithms learn patterns exclusively from unlabeled data. [1] Other frameworks in the spectrum of supervisions include weak- or semi-supervision , where a small portion of the data is tagged, and self-supervision .

  9. Siamese neural network - Wikipedia

    en.wikipedia.org/wiki/Siamese_neural_network

    Learning in twin networks can be done with triplet loss or contrastive loss. For learning by triplet loss a baseline vector (anchor image) is compared against a positive vector (truthy image) and a negative vector (falsy image). The negative vector will force learning in the network, while the positive vector will act like a regularizer.
