brainpy.nn.runners.OnlineTrainer#

class brainpy.nn.runners.OnlineTrainer(target, fit_method=None, **kwargs)[source]#

Online trainer for models with recurrent dynamics.

Parameters

  • target (Node) – The target model to train.

  • fit_method (OnlineAlgorithm, Callable, dict, str) –

    The fitting method applied to the target model. - It can be a string, which specify the shortcut name of the training algorithm.

    Like, fit_method='ridge' means using the RLS method. All supported fitting methods can be obtained through brainpy.nn.runners.get_supported_online_methods()

    • It can be a dict, whose “name” item specifies the name of the training algorithm, and the others parameters specify the initialization parameters of the algorithm. For example, fit_method={'name': 'ridge', 'beta': 1e-4}.

    • It can be an instance of brainpy.nn.runners.OnlineAlgorithm. For example, fit_meth=bp.nn.runners.RLS(alpha=1e-5).

    • It can also be a callable function.

  • **kwargs – The other general parameters for RNN running initialization.
