Generative models of brain dynamics
WebHere, we suggest that the RNN approach may be made computationally more powerful by its fusion with Bayesian inference techniques for nonlinear dynamical systems. In this scheme, we use an RNN as a generative model of dynamic input caused by the environment, e.g. of speech or kinematics.

WebThese were all generative models whose properties were explored by simulations. The first estimation of model parameters from data within an inferential framework in the late 1990s was closely followed by work with dynamical causal modelling (DCM). In parallel, the neural field models were developed.
WebApr 10, 2024 · In the comparison of MAPE values, the two methods based on generative adversarial network models are also better than MF and PF, as shown in Table 7 and Figure 6b. Comparing the cases of missing rates of 10% and 20%, the RMSE and MAPE changes in WFGAIN-GP and GAIN are small, indicating that generative adversarial …
WebGenerative models that evolve continuous time or discrete time likely coexist in the brain, mirroring the processes generating sensory data. While, at the level of sensory receptors, data arrive in continuous time, they may be generated in a sequential, categorical manner at a deeper level of hierarchical structure.
