Abstract

One quality that makes biological systems appear intelligent is their robustness to difficult circumstances. Robustness is crucial to intelligent behavior and important to AI research. We distinguish between ante-failure and post-failure robustness for causal tasks. Ante-failure robust systems resist failure, whereas post-failure systems incorporate the ability to recover from failure once it happens. We point out the power of post-failure robustness in AI problems, closely examining one example in visual motion tracking. Finally, we raise theoretical issues and argue for greater effort towards building post-failure robust systems.
