How it works
N-HiTS extends N-BEATS with multi-rate sampling: different stacks operate at different temporal scales.
Each stack uses MLP blocks with downsampling/interpolation basis functions.
Stacks are summed hierarchically — coarse-to-fine — to produce the multi-horizon forecast.
Pros and cons on this universe
Pros
- 50× cheaper than equivalent Transformers in the original paper.
- Mid-tier 918-paper rank.
- Confirmation arm to N-BEATS in our zoo.
Cons / failure modes
- Rank #17 IC — beaten by BITCN, TiDE, and most of the mixer cluster.
- RMSE-optimised; directional Sharpe is a separate question.
- Cluster-redundant with N-BEATS.
