AutoML - Time Series Forecast
Prerequisites
Install the [ts_forecast] option.
pip install "flaml[ts_forecast]"
Simple NumPy Example
import numpy as np
from flaml import AutoML
X_train = np.arange('2014-01', '2022-01', dtype='datetime64[M]')
y_train = np.random.random(size=84)
automl = AutoML()
automl.fit(X_train=X_train[:84], # a single column of timestamp
y_train=y_train, # value for each timestamp
period=12, # time horizon to forecast, e.g., 12 months
task='ts_forecast', time_budget=15, # time budget in seconds
log_file_name="ts_forecast.log",
eval_method="holdout",
)
print(automl.predict(X_train[84:]))
