%description
Implements forecasting methods for individual electricity load curves,
including Kernel Wavelet Functional (KWF), clustered KWF, Generalized
Additive Models (GAM), Multivariate Adaptive Regression Splines (MARS),
and Long Short-Term Memory (LSTM) models. Provides normalized dataset
adapters for iFlex, StoreNet, Smart-Grid Smart-City, Low Carbon London,
and REFIT; download and read support for IDEAL and GX; explicit Python
backend selection for TensorFlow-based LSTM fits; helpers for daily
segmentation and rolling-origin benchmarking; and compact shipped example
panels and benchmark-result datasets.
