plot_olden

The plot_olden() function generates specialized bar plots for visualizing Olden method results, which provide
importance measures specific to neural networks based on connection weight analysis. This method offers insights
into how input variables influence predictions through the network's synaptic connections.

A minimalistic library specifically designed to make the estimation of Machine
Learning (ML) techniques as easy and accessible as possible, particularly within the framework
of the Knowledge Discovery in Databases (KDD) process in data mining. The package provides
all the essential tools needed to efficiently structure and execute each stage of a predictive
or classification modeling workflow, aligning closely with the fundamental steps of the KDD
methodology, from data selection and preparation, through model building and tuning, to the
interpretation and evaluation of results using Sensitivity Analysis. The 'MLwrap' workflow is
organized into four core steps; preprocessing(), build_model(), fine_tuning(), and
sensitivity_analysis(). These steps correspond, respectively, to data preparation and
transformation, model construction, hyperparameter optimization, and sensitivity analysis.
The user can access comprehensive model evaluation results including fit assessment metrics,
plots, predictions, and performance diagnostics for ML models implemented through Neural Networks,
Random Forest, XGBoost, and Support Vector Machines algorithms. By streamlining these phases,
'MLwrap' aims to simplify the implementation of ML techniques, allowing analysts and data
scientists to focus on extracting actionable insights and meaningful patterns from large datasets,
in line with the objectives of the KDD process. Inspired by James et al. (2021) "An Introduction
