Robust Mean Teacher for Continual and Gradual Test-Time Adaptation. (arXiv:2211.13081v1 [cs.CV])

Since experiencing domain shifts during test-time is inevitable in practice,
test-time adaption (TTA) continues to adapt the model during deployment.
Recently, the area of continual and gradual test-time adaptation (TTA) emerged.
In contrast to standard TTA, continual TTA considers not only a single domain
shift, but a sequence of shifts. Gradual TTA further exploits the property that
some shifts evolve gradually over time. Since in both settings long test
sequences are present, error accumulation needs to be addressed for methods …
