Пример создания
class classname:
def fit(self, features, target):
self.value = target_train.mean()
def predict(self, new_features):
new_prediction = pd.Series(self.value, index=new_features.index)
return new_prediction
Пример использования
model = classname()
model.fit(features, target)
new_predictions = model.predict(features_test)
print(new_predictions)
