A Closer Look at In-Distribution vs. Out-of-Distribution Accuracy for Open-Set Test-time Adaptation
Three new research papers explore the nuances of test-time adaptation (TTA) in machine learning. One paper investigates the trade-off between recognizing in-distribution data and detecting out-of-distribution data, finding current methods struggle to balance both. Another introduces a framework called Tempora to evaluate TTA under time constraints, revealing that standard performance rankings do not hold when latency is a factor. The third paper systematically studies different masking strategies in continual TTA, suggesting that spatial masking is more stable for certain architectures while frequency masking can be competitive for others.
