%description
It offers a sophisticated and versatile tool for creating and evaluating
artificial intelligence based neural network models tailored for
regression analysis on datasets with continuous target variables.
Leveraging the power of neural networks, it allows users to experiment
with various hidden neuron configurations across two layers, optimizing
model performance through "5 fold"" or "10 fold"" cross validation. The
package normalizes input data to ensure efficient training and assesses
model accuracy using key metrics such as R squared (R2), Root Mean Square
Error (RMSE), Mean Absolute Error (MAE), and Percentage Error (PER). By
storing and visualizing the best performing models, it provides a
comprehensive solution for precise and efficient regression modeling
making it an invaluable tool for data scientists and researchers aiming to
harness AI for predictive analytics.
