Researchers have developed PaCTS, a novel method to enhance time-series foundation models (TSFMs) by using learned token embeddings as compact context surrogates. This approach generates instance-adaptive latent prompts, conditioned on visible context, which capture both global statistics and local temporal variations. PaCTS significantly improves forecasting accuracy across various context lengths and model architectures, outperforming models with longer input contexts while requiring less computational power. It also demonstrates superior improvements and out-of-distribution generalization compared to existing weight-space adaptation methods. AI
