  2. Mixture of experts - Wikipedia

    en.wikipedia.org/wiki/Mixture_of_experts

    The mixture of experts, being similar to the gaussian mixture model, can also be trained by the expectation-maximization algorithm, just like gaussian mixture models. Specifically, during the expectation step, the "burden" for explaining each data point is assigned over the experts, and during the maximization step, the experts are trained to ...

  3. Filter and refine - Wikipedia

    en.wikipedia.org/wiki/Filter_and_refine

    The mixture of experts (MoE) is a machine learning paradigm that incorporates FRP by dividing a complex problem into simpler, manageable sub-tasks, each handled by a specialized expert. [8] In the filtering stage, a gating mechanism—acting as a filter that determines the most suitable expert for each specific part of the input data based on ...

  4. Committee machine - Wikipedia

    en.wikipedia.org/wiki/Committee_machine

    Mixture of experts; In mixture of experts, the individual responses of the experts are non-linearly combined by means of a single gating network. Hierarchical mixture of experts; In hierarchical mixture of experts, the individual responses of the individual experts are non-linearly combined by means of several gating networks arranged in a ...

    en.wikipedia.org/wiki/DBRX

    DBRX is an open-sourced large language model (LLM) developed by Mosaic ML team at Databricks, released on March 27, 2024. [1] [2] [3] It is a mixture-of-experts transformer model, with 132 billion parameters in total. 36 billion parameters (4 out of 16 experts) are active for each token. [4]

  6. Mamba (deep learning architecture) - Wikipedia

    en.wikipedia.org/wiki/Mamba_(deep_learning...

    MoE Mamba represents a pioneering integration of the Mixture of Experts (MoE) technique with the Mamba architecture, enhancing the efficiency and scalability of State Space Models (SSMs) in language modeling.

  7. Product of experts - Wikipedia

    en.wikipedia.org/wiki/Product_of_Experts

    Product of experts (PoE) is a machine learning technique. It models a probability distribution by combining the output from several simpler distributions. It was proposed by Geoffrey Hinton in 1999, [1] along with an algorithm for training the parameters of such a system.

  8. Dirichlet process - Wikipedia

    en.wikipedia.org/wiki/Dirichlet_process

    For instance, mixtures of Gaussian process experts, where the number of required experts must be inferred from the data. [8] [9] As draws from a Dirichlet process are discrete, an important use is as a prior probability in infinite mixture models. In this case, is the parametric set of component distributions. The generative process is ...

  9. Mixture - Wikipedia

    en.wikipedia.org/wiki/Mixture

    [8] [9] Mixtures differ from chemical compounds in the following ways: The substances in a mixture can be separated using physical methods such as filtration, freezing, and distillation. There is little or no energy change when a mixture forms (see Enthalpy of mixing). The substances in a mixture keep their separate properties.
