Aspect-based Forecasting Accuracy

Model Radar 🎯

A framework for aspect-based evaluation of time series forecasting models based on Nixtla's ecosystem.

Overview

Model Radar introduces a novel aspect-based forecasting evaluation approach that goes beyond traditional aggregate metrics. Our framework enables:

• Fine-grained performance analysis across different forecasting aspects
• Better understanding of model behavior in varying conditions
• More informed model selection based on specific use case requirements

🚀 Getting Started

Check the notebooks folder for usage examples and tutorials.

Check ModelRadar-Experiments repository for a thorough application of ModelRadar.

Installation

You can install modelradar using pip:

pip install modelradar

[Optional] Installation from source

To install modelradar from source, clone the repository and run the following command:

git clone https://github.com/vcerqueira/modelradar
pip install -e modelradar

Prerequisites

Required dependencies:

utilsforecast==0.2.11
numpy==1.26.4
plotnine==0.14.5

Examples

Besides the examples in the notebooks folder, here's some outputs you can get from modelradar:

• Spider chart with overview on several dimensions:

• Parallel coordinates chart with overview on several dimensions:

• Barplot chart controlling for a given variable (in this case, anomaly status):

• Grouped bar plot showing win/draw/loss ratios wrt different models:
