TimeNet addresses a critical bottleneck in Temporal Foundation Model development by providing a unified infrastructure that decouples raw time-series data from specific task definitions. This approach allows researchers to combine heterogeneous datasets for large-scale joint training, resulting in a demonstrated 14% improvement in F1 scores across diverse tasks like forecasting and generation. By standardizing how temporal signals are represented, the project significantly lowers the barrier to building generalizable models that operate across multiple domains and modalities.
TimeNet: An Extensible Unified Data Infrastructure for Next-Generation Temporal Foundation Models
arXiv:2610.04407v1 Announce Type: new Abstract: Temporal Foundation Models (TFMs) aim to generalize across domains, datasets, and tasks. Yet, their development remains constrained by fragmented, task-specific data formats, annotations, and processing pipelines. We introduce TimeNet, an open-source data standard and scalable infrastructure that decouples temporal data from task definitions and represents signals, metadata, annotations, and supervision in a shared, extensible data model. TimeNet supports multimodal signals with regular, irregular, or ordinal time axes and expresses different task families (including classification, forecasting, temporal localization, question answering, generation, and editing) as reusable views over the same recordings. This shared representation enables heterogeneous time-series datasets to be combined for large-scale model training across domains, modalities, and tasks. We demonstrate TimeNet by transcoding datasets with 1.5M task instances spanning diverse domains, modalities, temporal scales, and forms of supervision, while retaining practical I/O performance relative to native formats. TimeNet enables an existing TFN training pipeline to support joint training on a configurable number of heterogeneous datasets through configuration changes alone. We show this capability by training TFM across multiple datasets and tasks, obtaining a 14% F1 score improvement compared with models trained on individual datasets. These results show that TimeNet provides the data and systems foundation needed to move beyond task- and dataset-specific TFMs toward models that can learn jointly across heterogeneous domains, modalities, temporal scales, and forms of supervision from a common data model.
