TemplateTensorflowModel

Template file for a prediction model based on TensorflowModel
class easypheno.model._template_tensorflow_model.TemplateTensorflowModel(task, optuna_trial, encoding=None, n_outputs=1, n_features=None, width_onehot=None, batch_size=None, n_epochs=None, early_stopping_point=None)

Bases: easypheno.model._tensorflow_model.TensorflowModel

Template file for a prediction model based on TensorflowModel

See BaseModel and TensorflowModel for more information on the attributes.

Steps you have to do to add your own model:

  1. Copy this template file and rename it according to your model (will be the name to call it later on on the command line)

  2. Rename the class and add it to easypheno.model.__init__.py

  3. Adjust the class attributes if necessary

  4. Define your model in define_model()

  5. Define the hyperparameters and ranges you want to use for optimization in define_hyperparams_to_tune().

    CAUTION: Some hyperparameters are already defined in common_hyperparams(), which you can directly use here. Some of them are already suggested in TensorflowModel.

  6. Test your new prediction model using toy data

Parameters

  • task (str) –

  • optuna_trial (optuna.trial.Trial) –

  • encoding (str) –

  • n_outputs (int) –

  • n_features (int) –

  • width_onehot (int) –

  • batch_size (int) –

  • n_epochs (int) –

  • early_stopping_point (int) –

standard_encoding = Ellipsis
possible_encodings = [Ellipsis]
define_model(self)

Definition of the actual prediction model.

Use param = self.suggest_hyperparam_to_optuna(PARAM_NAME_IN_DEFINE_HYPERPARAMS_TO_TUNE) if you want to use the value of a hyperparameter that should be optimized. The function needs to return the model object.

See BaseModel for more information.

define_hyperparams_to_tune(self)

Define the hyperparameters and ranges you want to optimize. Caution: they will only be optimized if you add them via self.suggest_hyperparam_to_optuna(PARAM_NAME) in define_model()

See BaseModel for more information on the format and options.

Check TensorflowModel for already defined (and for some cases also suggested) hyperparameters.
