Researchers have developed GALA, a novel two-stage approach for generating time series data from natural language descriptions. This method first aligns a pre-trained text encoder with a time-series foundation model using contrastive learning and an auxiliary generative loss. The aligned embeddings then drive a flow-matching generator, improving the adherence of generated time series to textual prompts. GALA significantly outperforms existing methods on the TSFragment-600K dataset across various metrics, demonstrating its effectiveness in controllable time series synthesis. AI
