The paper introduces STeP-TS, a compact one‑layer convolutional model for multivariate time‑series forecasting that learns a shared bank of multi‑scale temporal filters for each variable. Lightweight variable‑specific scalar weights modulate the contribution of each filter, allowing the model to capture both shared temporal patterns and variable‑specific dynamics. The learned weights and filter‑output energy are used for structured pruning, reducing computational complexity with minimal loss in performance, and an amplitude‑adaptive normalization preserves variable‑dependent temporal amplitudes.

Timer‑M1 is a pretrained multivariate time‑series foundation model that learns with primitives for zero‑shot forecasting. It uses a primitive‑based data synthesis and pretraining pipeline to generate series with shared temporal and relational patterns, assembling them into multivariate samples with distinct channel roles. The model employs gated two‑dimensional Transformer blocks that dynamically allocate cross‑variate attention, achieving top performance on several large‑scale forecasting benchmarks.
