Memristors and SIRENs: This work is built on two key innovations. Memristors are emerging non-volatile memory devices used for "in-memory computing," drastically reducing data movement and energy consumption. SIRENs (Sinusoidal Representation Networks) are a class of neural networks using periodic sine activation functions, which this research shows are highly effective for representing complex physical signals like trajectories and density fields on memristor hardware.
Hardware Non-Idealities: The promise of memristive computing is tempered by real-world hardware challenges. Devices suffer from conductance drift (losing their programmed value over time), read/write noise (stochastic variations during operation), and device faults (devices getting stuck). These non-idealities can severely degrade AI model performance, making them unsuitable for mission-critical tasks without effective mitigation.
Advanced Mitigation Strategies: The research proves that performance can be restored through a combination of software and hardware techniques. Temporal Averaging involves running a network layer multiple times and averaging the output to cancel out random noise. Bit-Slicing uses multiple physical memristor devices to represent a single, higher-precision weight, increasing robustness. Together, these methods make memristor-based AI viable.
97.7%
Reduction in Task Error
For the complex task of learning an asteroid's gravitational field (geodesy), the proposed mitigation techniques reduced the final error loss from a non-functional 0.3 to a highly competitive 0.007, demonstrating a near-complete recovery of performance on noisy hardware.

Case Study: Asteroid Geodesy (geodesyNets)
A key test for this technology was to perform geodesy—learning the shape and mass distribution of the asteroid Eros using only simulated gravitational measurements. Without mitigation, the memristor-based model was unable to learn any discernible structure, resulting in a random cloud of points. After applying temporal averaging and bit-slicing, the same model successfully reconstructed the distinct, elongated shape of Eros from scratch. This result proves the system's ability to handle complex, on-board scientific analysis, transforming a noisy hardware platform into a viable tool for autonomous space exploration.
