RecSim NG stands as an elegant solution for modeling uncertainty in recommender ecosystems. Crafted with flexibility and scalability in mind, it allows researchers and practitioners to simulate multi-agent recommender systems seamlessly. This user-friendly guide will take you through the essentials of installing and utilizing RecSim NG effectively.

Installation: Getting RecSim NG Up and Running

Embarking on your journey with RecSim NG requires a simple installation process. Follow these steps to set it up:

• Use pip to install RecSim NG directly from PyPI:

pip install recsim_ng

• Clone the RecSim NG repository:

git clone https://github.com/google-research/recsim_ng

• Navigating into the application:

cd recsim_ng/recsim_ng/applications/

• And finally, run the demo simulation:

python ecosystem_simulation_demo.py

Understanding RecSim NG Through Analogy

Think of RecSim NG as a sophisticated theater stage, where various actors (agents) play their roles in a narrative (recommender system) that unfolds dynamically. Each actor (agent) possesses unique behaviors and stories (recommendations) that contribute to the overall plot of user engagement and interaction. The platform’s ability to model these interactions using probabilities is akin to a director refining each scene based on audience reactions, ensuring that the performances resonate well and adaptively respond to uncertainties, just like in real life.
