Researchers have introduced DAGFormer, a novel Transformer architecture that enhances efficiency by predicting cross-layer connections globally. This approach, which differs from layer-by-layer routing methods, allows for direct connections from earlier to later layers, with the strength of each connection dynamically controlled based on input tokens. DAGFormer has demonstrated significant improvements in perplexity on benchmarks like WikiText-2 and has shown better performance on downstream tasks and instruction tuning compared to vanilla Transformers and other routing architectures.
