arXiv:2607.07500v1 Announce Type: new Abstract: Time series classification (TSC) is dominated by a two-stage paradigm: train a feature encoder -- either from scratch on the target dataset or via pretraining on large corpora -- and then fit a task-specific classifier on top. While effective, this decoupling optimizes representation learning independently of the classification objective, requires per-dataset training, and prevents the model from exploiting label information during inference. We introduce TimEE, a 4.5M-parameter foundation model for end-to-end TSC via in-context learning. Given a
The development of TimEE capitalizes on the broader trend of foundation models and in-context learning being applied to specialized data types, seeking to overcome limitations of traditional two-stage time series classification.
A 4.5M-parameter foundation model for time series classification could significantly advance AI's capability to understand and predict dynamic systems across various industries, creating more efficient and autonomous operations.
The shift from a two-stage paradigm (feature encoding + classifier) to an end-to-end foundation model for time series classification could streamline development, improve accuracy, and enable more flexible model deployment without per-dataset retraining.
