Highlights
- Uses Jev 1.13.0 as the case study model for structured System 1 decision making on time-series tasks.
- Covers time-series classification, event type prediction, oil temperature direction, and stock movement prediction.
- Continuous forecasting targets are converted into discrete decisions to fit the model interface.
- Reports stronger performance on selected explicit temporal patterns and on event type prediction.
- Finds near-chance discrimination on many numerical sequence classification tasks and stock movement prediction.
Questions about this entry
Short answers drawn from the linked project or page.
It evaluates Jev 1.13.0, treated as a structured System 1 model that directly outputs answers and their probabilities, on time-series decision tasks, using a unified framework scored with accuracy and AUC.
Four settings: time-series classification, event type prediction, oil temperature direction, and stock movement prediction.
A unified evaluation framework reports accuracy and AUC, and some datasets also reveal a gap between ranking quality and final decision accuracy.
Continuous forecasting targets are converted into discrete decisions so they fit the model interface, which outputs an answer together with its probability.
Results show stronger performance on selected explicit temporal patterns and on event type prediction.
It shows near-chance discrimination on many numerical sequence classification tasks and on stock movement prediction, which the authors attribute to open issues in temporal representation, domain adaptation, and decision-score alignment.
Yes. Standardized sample construction, model calls, and result recording are set up so the evaluation can be extended to future models.
