ChorusTIC

A support-conditioned foundation model for training-free univariate and multivariate time series classification.

Using ChorusTIC for time series classification

A support-conditioned foundation model for training-free univariate and multivariate time series classification.

In this benchmark, ChorusTIC is evaluated using training-free in-context classification. Checkpoint information: ChorusTIC.ckpt (step 6000). Check the results below for the settings and dataset scopes with published scores.

Evaluated configurations

Native in-context inference

Classifier heads are grouped under their shared pretrained model here. They remain separate leaderboard entries because they are different experimental configurations.

Organization: GDUT · Huawei Noah’s Ark Lab · Université Paris Cité · MBZUAI · Shantou University
Parameters: Not reported by authors
Checkpoint used: ChorusTIC.ckpt (step 6000)
Input Type: Univariate + multivariate time series
Inference: Training-free in-context classification

ChorusTIC classification benchmark results

Compare accuracy and average rank only within the same evaluation setting and dataset scope. Standard uses the official training splits; 5-shot and 10-shot use different budget-feasible subsets. Rank and average rank include other models in the full comparison set. Scores are not averaged across configurations.

For comparisons with other backbones, open the foundation model classification leaderboard and use the same setting and scope. The few-shot evaluation protocol explains the label budgets.
