The class structure and details algorithmic overview is depicted in the following diagram:

As shown, there are three distinct objects comprising `FreqAI`:
|
|
|
|
* IFreqaiModel
|
|
* Singular persistent object containing all the necessary logic to collect data, store data, process data, engineer features, run training, and inference models.
|
|
* FreqaiDataKitchen
|
|
* A non-persistent object which is created uniquely for each unique asset/model. Beyond metadata, it also contains a variety of data processing tools.
|
|
* FreqaiDataDrawer
|
|
* Singular persistent object containing all the historical predictions, models, and save/load methods.
|
|
|
|
There are a variety of built-in prediction models which inherit directly from `IFreqaiModel` including:
|
|
|
|
* CatboostRegressor
|
|
* CatboostRegressorMultiTarget
|
|
* CatboostClassifier
|
|
* LightGBMRegressor
|
|
* LightGBMRegressorMultiTarget
|
|
* LightGBMClassifier
|
|
* XGBoostRegressor
|
|
* XGBoostRegressorMultiTarget
|
|
* XGBoostClassifier
|
|
|
|
Each of these have full access to all methods in `IFreqaiModel`. And can therefore, override any of those functions at will. However, advanced users will likely stick to overriding `fit()`, `train()`, `predict()`, and `data_cleaning_train/predict()`. |
