|
|
|
94 Predicts a categorical sample metadata column using a supervised learning
|
|
|
95 classifier. Uses nested stratified k-fold cross validation for automated
|
|
|
96 hyperparameter optimization and sample prediction. Outputs predicted values
|
|
|
97 for each input sample, and relative importance of each feature for model
|
|
|
98 accuracy.

|
|
100 Parameters
|
|
|
101 ----------
|
|
|
102 table : FeatureTable[Frequency]
|
|
|
103 Feature table containing all features that should be used for target
|
|
|
104 prediction.
|
|
|
105 metadata : MetadataColumn[Categorical]
|
|
|
106 Categorical metadata column to use as prediction target.
|
|
|
107 cv : Int % Range(1, None), optional
|
|
|
108 Number of k-fold cross-validations to perform.
|
|
|
109 random_state : Int, optional
|
|
|
110 Seed used by random number generator.
|
|
|
111 n_estimators : Int % Range(1, None), optional
|
|
|
112 Number of trees to grow for estimation. More trees will improve
|
|
|
113 predictive accuracy up to a threshold level, but will also increase
|
|
|
114 time and memory requirements. This parameter only affects ensemble
|
|
|
115 estimators, such as Random Forest, AdaBoost, ExtraTrees, and
|
|
|
116 GradientBoosting.
|
|
|
117 estimator : Str % Choices('RandomForestClassifier', 'ExtraTreesClassifier', 'GradientBoostingClassifier', 'AdaBoostClassifier', 'KNeighborsClassifier', 'LinearSVC', 'SVC'), optional
|
|
|
118 Estimator method to use for sample prediction.
|
|
|
119 parameter_tuning : Bool, optional
|
|
|
120 Automatically tune hyperparameters using random grid search.
|
|
|
121 missing_samples : Str % Choices('error', 'ignore'), optional
|
|
|
122 How to handle missing samples in metadata. "error" will fail if missing
|
|
|
123 samples are detected. "ignore" will cause the feature table and
|
|
|
124 metadata to be filtered, so that only samples found in both files are
|
|
|
125 retained.
|
|
|
126
|
|
|
127 Returns
|
|
|
128 -------
|
|
|
129 predictions : SampleData[ClassifierPredictions]
|
|
|
130 Predicted target values for each input sample.
|
|
|
131 feature_importance : FeatureData[Importance]
|
|
|
132 Importance of each input feature to model accuracy.
|
|
9
|
133 probabilities : SampleData[Probabilities]
|
|
|
134 Predicted class probabilities for each input sample.
