  2. Group dynamics - Wikipedia

    en.wikipedia.org/wiki/Group_dynamics

    Group dynamics is a system of behaviors and psychological processes occurring within a social group (intragroup dynamics), or between social groups (intergroup dynamics). The study of group dynamics can be useful in understanding decision-making behaviour, tracking the spread of diseases in society, creating effective therapy techniques, and ...

  3. Dynamic range - Wikipedia

    en.wikipedia.org/wiki/Dynamic_range

    Audio engineers use dynamic range to describe the ratio of the amplitude of the loudest possible undistorted signal to the noise floor, say of a microphone or loudspeaker. [18] Dynamic range is therefore the signal-to-noise ratio (SNR) for the case where the signal is the loudest possible for the system. For example, if the ceiling of a device ...

    en.wikipedia.org/wiki/Systems-centered_therapy

    Systems-centered therapy (SCT) is a particular form of group therapy based on the Theory of Living Human Systems developed by Yvonne Agazarian.The theory postulates that living human systems survive, develop, and transform from simple to complex through discriminating and integrating information.

  5. Random dynamical system - Wikipedia

    en.wikipedia.org/wiki/Random_dynamical_system

    In the mathematical field of dynamical systems, a random dynamical system is a dynamical system in which the equations of motion have an element of randomness to them. Random dynamical systems are characterized by a state space S, a set of maps from S into itself that can be thought of as the set of all possible equations of motion, and a probability distribution Q on the set that represents ...

  6. Metastability in the brain - Wikipedia

    en.wikipedia.org/wiki/Metastability_in_the_brain

    The dynamic core hypothesis (DCH) reflects the use and disuse of interconnected neuronal networks during stimulation of this region. A computer model of 65,000 spiking neurons [8] shows that neuronal groups existing in the cortex and thalamus interact in the form of synchronous oscillation. The interaction between distinct neuronal groups forms ...

  8. Partially observable Markov decision process - Wikipedia

    en.wikipedia.org/wiki/Partially_observable...

    A POMDP models an agent decision process in which it is assumed that the system dynamics are determined by an MDP, but the agent cannot directly observe the underlying state. Instead, it must maintain a sensor model (the probability distribution of different observations given the underlying state) and the underlying MDP. Unlike the policy ...
