XGBoostClassification

class XGBoostClassification(max_depth=3, num_round=300, eta=0.3, gpu=-1)

Class for the XGBoost Decoder

Parameters:

• max_depth (integer, optional, default 3) – the maximum depth of the trees

• num_round (integer, optional, default 300) – the number of trees that are fit

• eta (float, optional, default 0.3) – the learning rate

• gpu (integer, optional, default -1) – if the gpu version of xgboost is installed, this can be used to select which gpu to use for negative values (default), the gpu is not used

fit(X_flat_train, y_train)

Train XGBoost Decoder

Parameters:

• X_flat_train (numpy 2d array of shape [n_samples,n_features]) – This is the neural data. See example file for an example of how to format the neural data correctly

• y_train (numpy 1d array of shape (n_samples), with integers) –

  representing classes or 2d array of shape [n_samples, n_outputs] in

  1-hot form. This is the outputs that are being predicted

predict(X_flat_test)

Predict outcomes using trained XGBoost Decoder

Parameters:

X_flat_test (numpy 2d array of shape [n_samples,n_features]) – This is the neural data being used to predict outputs.

Returns:

y_test_predicted – The predicted outputs

Return type:

numpy 1d array with integers as classes
