Reality Gap

The reality gap refers to the discrepancies between the behavior of simulated models and their real-world counterparts, particularly in the context of robotics and AI. This gap arises due to simplifications and assumptions made during the modeling process, which may not accurately capture the complexities of real-world physics, sensor noise, and environmental variability. Mathematically, the reality gap can be analyzed through the lens of model validation and uncertainty quantification, where the fidelity of the simulation is assessed against empirical data. Techniques to mitigate the reality gap include enhanced modeling approaches, such as using high-fidelity simulations and incorporating real-world data into the training process. Addressing the reality gap is essential for ensuring that AI systems perform reliably when deployed in practical applications.
