    Learning as filtering: Implications for spike-based plasticity. by Jannes Jegminat, Simone Carlo Surace, Jean-Pascal Pfister

    Published 2022-02-01
    “…Most normative models in computational neuroscience describe the task of learning as the optimisation of a cost function with respect to a set of parameters. However, learning as optimisation fails to account for a time-varying environment during the learning process and the resulting point estimate in parameter space does not account for uncertainty. …”
