Most-Recent Anchoring with Recurrent Ordering for Time Series Forecasting
Jung Min Choi, Ngoc Son Le, Ibram Abdelmalak +2
Long-term forecasting models commonly process all patches in a look-back window using the same fixed stack. Older contextual patches and recent evidence therefore receive the same…

Dual-Context Analog Retrieval for Time Series Forecasting
Jung Min Choi, Ngoc Son Le, Ibram Abdelmalak +2
Most long-term time-series forecasting models map the look-back window directly to the full horizon in a single pass. While efficient, this design does not explicitly identify whic…

Channel Dependence, Limited Lookback Windows, and the Simplicity of Datasets: How Biased is Time Series Forecasting?
Ibram Abdelmalak, Kiran Madhusudhanan, Jungmin Choi +4
In Long-term Time Series Forecasting (LTSF), the lookback window is a critical hyperparameter often set arbitrarily, undermining the validity of model evaluations. We argue that th…
