Attention Residuals
Learned, attention-style weights over earlier layer outputs replace the plain residual sum.
A standard residual connection adds every earlier update with weight one. AttnRes lets each layer attend over earlier layer outputs and weight their contributions.
Full and block variants exist; Kimi Linear already used the idea. Reported gains are consistent but modest, for a few percent extra training and inference cost.
