Automated Time Series Forecasting
Project description
AutoTS
Model Selection for Multiple Time Series
Simple package for comparing and predicting with open-source time series implementations.
For other time series needs, check out the list here.
Features
- Twenty available model classes, with tens of thousands of possible hyperparameter configurations
- Finds optimal time series models by genetic programming
- Handles univariate and multivariate/parallel time series
- Point and probabilistic forecasts
- Ability to handle messy data by learning optimal NaN imputation and outlier removal
- Ability to add external known-in-advance regressor
- Allows automatic ensembling of best models
- Multiple cross validation options
- Subsetting and weighting to improve search on many multivariate series
- Option to use one or a combination of metrics for model selection
- Import and export of templates allowing greater user customization
Installation
pip install autots
This includes dependencies for basic models, but additonal packages are required for some models and methods.
Basic Use
Input data is expected to come in either a long or a wide format:
- The wide format is a
pandas.DataFrame
with apandas.DatetimeIndex
and each column a distinct series. - The long format has three columns:
- Date (ideally already in pd.DateTime format)
- Series ID. For a single time series, series_id can be
= None
. - Value
- For long data, the column name for each of these is passed to .fit() as
date_col
,id_col
, andvalue_col
. No parameters are needed for wide data.
# also: _hourly, _daily, _weekly, or _yearly
from autots.datasets import load_monthly
df_long = load_monthly()
from autots import AutoTS
model = AutoTS(
forecast_length=3,
frequency='infer',
prediction_interval=0.9,
ensemble='all',
model_list='superfast',
max_generations=5,
num_validations=2,
validation_method='even',
)
model = model.fit(df_long, date_col='datetime', value_col='value', id_col='series_id')
# Print the details of the best model
print(model)
prediction = model.predict()
# point forecasts dataframe
forecasts_df = prediction.forecast
# accuracy of all tried model results
model_results = model.results()
# and aggregated from cross validation
validation_results = model.results("validation")
