Model Model¶
Model subclasses are responsible for training themselves on records, making predictions about the value of a feature in the record, and assessing their prediction accuracy.
- class dffml.model.model.Model(config)[source]¶
Abstract base class which should be derived from and implemented using various machine learning frameworks or concepts.
- CONFIG¶
alias of
ModelConfig
- class dffml.model.model.ModelConfig(location: str, features: dffml.feature.feature.Features, location_save: dffml.df.types.DataFlow, location_load: dffml.df.types.DataFlow)[source]¶
- no_enforce_immutable()¶
By default, all properties of a config object are immutable. If you would like to mutate immutable properties, you must explicitly call this method using it as a context manager.
Examples
>>> from dffml import config >>> >>> @config ... class MyConfig: ... C: int >>> >>> config = MyConfig(C=2) >>> with config.no_enforce_immutable(): ... config.C = 1
- class dffml.model.model.ModelContext(parent: Model)[source]¶
Abstract base class which should be derived from and implemented using various machine learning frameworks or concepts.
- abstract async predict(sources: SourcesContext) AsyncIterator[Record] [source]¶
Uses trained data to make a prediction about the quality of a record.
- class dffml.model.model.SimpleModel(config: BaseConfig)[source]¶
- CONTEXT¶
alias of
SimpleModelNoContext
- disk_path(extention: Optional[str] = None)[source]¶
We do this for convenience of the user so they can usually just use the default location and if they train models with different parameters this method transparently to the user creates a filename unique the that configuration of the model where data is saved and loaded.
- property parent¶
Simple models are both the parent and the context. This property is used to fake out anything attempting to access the model context’s parent.
