  • get_best_model for Lazy* classes (see updated docs)
  • bring LazyMTS back
  • add Exponential Smoothing, ARIMA and Theta models to ClassicalMTS and Lazy*MTS
  • add RandomForest and XGBoost to Lazy*Classifier and Lazy*Regressor as baselines
  • Add MedianVotingRegressor: using the median of predictions from an ensemble of regressors

version 0.24.5

  • Update LazyDeepMTS: No more LazyMTS class, instead, you can use LazyDeepMTS with n_layers=1
  • Specify forecasting horizon in LazyDeepMTS (see updated docs and examples/lazy_mts_horizon.py)
  • New class ClassicalMTS for classsical models (for now VAR and VECM adapted from statsmodels) in multivariate time series forecasting
  • partial_fit for CustomClassifier and CustomRegressor

version 0.23.1

  • Copula simulation for time series residuals in classes MTS and DeepMTS
    • based on copulas of in-sample residuals: vine-tll (default), vine-bb1, vine-bb6, vine-bb7, vine-bb8, vine-clayton, vine-frank, vine-gaussian, vine-gumbel, vine-indep, vine-joe, vine-student
    • scp-vine-tll (default), scp-vine-bb1, scp-vine-bb6, scp-vine-bb7, scp-vine-bb8, scp-vine-clayton, scp-vine-frank, scp-vine-gaussian, scp-vine-gumbel, scp-vine-indep, scp-vine-joe, scp-vine-student
    • scp2-vine-tll, scp2-vine-bb1, scp2-vine-bb6, scp2-vine-bb7, scp2-vine-bb8, scp2-vine-clayton, scp2-vine-frank, scp2-vine-gaussian, scp2-vine-gumbel, scp2-vine-indep, scp2-vine-joe, scp2-vine-student
  • cross_val_score: time series cross-validation for MTS and DeepMTS Technical:
  • Do not scale sparse matrices before training
  • Add MaxAbsScaler

version 0.22.7

  • Implement new types of predictive simulation intervals (type_pis): independent bootstrap, block bootstrap, 2 variants of split conformal prediction in class MTS (see updated docs)
  • Gaussian prediction intervals type_pi == "gaussian" in class MTS
  • Implement Winkler score in LazyMTS and LazyDeepMTS for probabilistic forecasts
  • Use conformalized Estimators in MTS (see examples/mts_conformal_not_sims.py)
  • Include block_size for block bootstrapping methods for *MTS classes

version 0.20.6

Technical:

  • Import all_estimators from sklearn.utils
  • Use both sparse and sparse_output in OneHotEncoder (for compatibility with older versions of sklearn)

version 0.18.0

version 0.17.2

  • self.n_classes_ = len(np.unique(y)) # for compatibility with sklearn

version 0.17.1

  • preprocessing for all LazyDeep*

version 0.17.0

  • Attribute estimators (a list of Estimator's as strings) for LazyClassifier, LazyRegressor, LazyDeepClassifier, LazyDeepRegressor, LazyMTS, and LazyDeepMTS
  • New documentation for the package, using pdoc (not pdoc3)
  • Remove external regressors xreg at inference time for MTS and DeepMTS
  • New class Downloader: querying the R universe API for datasets (see https://thierrymoudiki.github.io/blog/2023/12/25/python/r/misc/mlsauce/runiverse-api2 for similar example in mlsauce)
  • Add custom metric to Lazy*
  • Rename Deep regressors and classifiers to Deep* in Lazy*
  • Add attribute sort_by to Lazy* -- sort the data frame output by a given metric
  • Add attribute classes_ to classifiers (ensure consistency with sklearn)

version 0.16.8

  • plot method for MTS objects

version 0.12.1

  • Begin residuals simulation

  • less dependencies in setup

version 0.11.0

  • Implement RandomBagRegressor
  • Use of a DataFrame in MTS

version 0.10.0

  • rename attributes with underscore
  • add more examples to documentation

version 0.9.6

  • Fix numbers' simulations

version 0.9.4

  • Remove memoize from Simulator

version 0.9.2

  • loosen the range of Python packages versions

version 0.9.0

  • Add Poisson and Laplace regressions to GLMRegressor
