Researchers have developed HART, a novel time series foundation model that combines attention and RWKV blocks to improve long-horizon forecasting. The model addresses the degradation observed in pure RWKV models when predicting far into the future without new data, a phenomenon they term Placeholder Idling Decay (PID). Experiments on GIFT-Eval and TIME-Benchmark demonstrate that HART outperforms pure RWKV and matches the performance of a much larger Transformer model on certain metrics, while using significantly fewer parameters.
