  2. Concept drift - Wikipedia

    en.wikipedia.org/wiki/Concept_drift

    When concept drift is detected, the current model is no longer up-to-date and must be replaced by a new one to restore prediction accuracy. [11] [12] A shortcoming of reactive approaches is that performance may decay until the change is detected. Tracking solutions seek to track the changes in the concept by continually updating the model.

  3. Time delay neural network - Wikipedia

    en.wikipedia.org/wiki/Time_delay_neural_network

    Time delay neural network (TDNN) [1] is a multilayer artificial neural network architecture whose purpose is to 1) classify patterns with shift-invariance, and 2) model context at each layer of the network. Shift-invariant classification means that the classifier does not require explicit segmentation prior to classification.

  4. Soar (cognitive architecture) - Wikipedia

    en.wikipedia.org/wiki/Soar_(cognitive_architecture)

    Soar [1] is a cognitive architecture, [2] originally created by John Laird, Allen Newell, and Paul Rosenbloom at Carnegie Mellon University.. The goal of the Soar project is to develop the fixed computational building blocks necessary for general intelligent agents – agents that can perform a wide range of tasks and encode, use, and learn all types of knowledge to realize the full range of ...

  5. Recurrent neural network - Wikipedia

    en.wikipedia.org/wiki/Recurrent_neural_network

    Recurrent neural networks (RNNs) are a class of artificial neural network commonly used for sequential data processing. Unlike feedforward neural networks, which process data in a single pass, RNNs process data across multiple time steps, making them well-adapted for modelling and processing text, speech, and time series.

  6. Diffusion map - Wikipedia

    en.wikipedia.org/wiki/Diffusion_map

    To describe the long-term behavior of the point distribution of a system of stochastic differential equations, we can use = and the resulting Markov chain approximates the Fokker–Planck diffusion. With α = 0 {\displaystyle \alpha =0} , it reduces to the classical graph Laplacian normalization.

  7. Actor model - Wikipedia

    en.wikipedia.org/wiki/Actor_model

    The actor model in computer science is a mathematical model of concurrent computation that treats an actor as the basic building block of concurrent computation. In response to a message it receives, an actor can: make local decisions, create more actors, send more messages, and determine how to respond to the next message received.

  8. Channel state information - Wikipedia

    en.wikipedia.org/wiki/Channel_state_information

    In wireless communications, channel state information (CSI) is the known channel properties of a communication link.This information describes how a signal propagates from the transmitter to the receiver and represents the combined effect of, for example, scattering, fading, and power decay with distance.

  9. Discrete-event simulation - Wikipedia

    en.wikipedia.org/wiki/Discrete-event_simulation

    The simulation must keep track of the current simulation time, in whatever measurement units are suitable for the system being modeled. In discrete-event simulations, as opposed to continuous simulations, time 'hops' because events are instantaneous – the clock skips to the next event start time as the simulation proceeds.
