%description
Neural network framework based on Generalized Additive Models from Hastie
& Tibshirani (1990, ISBN:9780412343902), which trains a different neural
network to estimate the contribution of each feature to the response
variable. The networks are trained independently leveraging the local
scoring and backfitting algorithms to ensure that the Generalized Additive
Model converges and it is additive. The resultant Neural Network is a
highly accurate and interpretable deep learning model, which can be used
for high-risk AI practices where decision-making should be based on
accountable and interpretable algorithms.
