Mechanism diagram · CNN / TCN
How it works
BITCN runs two TCN stacks in parallel — one causal (sees only past), one reverse-causal (sees only future within the lookback window).
The two streams are fused before the forecast head — bidirectional information without breaking the lookback boundary.
Dilated convolutions expand the receptive field exponentially with depth.
Pros and cons on this universe
Pros
- Campaign-best BNB long (+0.298) and ETH long (+0.239) per-coin IC.
- Not in the literature top-20 — a useful counter-example to literature priors.
- Rank #11 IC.
Cons / failure modes
- Pairwise IC ρ = +0.999 with StemGNN — almost perfectly redundant.
- No dossier in the research base.
- Bidirectional design slightly more expensive than causal TCN.
